Pro/ENGINEER Wildfire for Designers Introduction

Pro/ENGINEER Wildfire 3.0To make the designing process simple and quick, Pro/ENGINEER Wildfire 3.0 has divided the steps of designing into different modules. This means that each step of designing is completed in a different module. For example, generally a design process consists of the following steps:

• Sketching using the basic sketch entities.

• Converting the sketch into features and parts.

• Assembling different parts and analyzing them.

• Documenting parts and the assembly in terms of drawings views.

• Manufacturing the final part and assembly.






Feature-Based Nature

Figure A Model displaying the counterbore holes

ExampleFigure A shows a part consisting of a counterbore hole at the center and six counterbore holes around it at some Bolt Circle Diameter (BCD).

Now, consider a case where you have to change all the outer counterbore holes to drill holes keeping the central counterbore hole and the BCD for the outer holes same. You also, have to change the number of holes from six to eight.

• A feature is defined as the smallest building block and any solid model created in Pro/ENGINEER Wildfire 3.0 is an integration of a number of these building blocks.

• Each feature can be edited individually to bring in any change in the solid model.






Pro/ENGINEER Wildfire 3.0 allows you to make this modification by just modifying some values in the same part, see Figure B. This shows that the solid parts created in Pro/ENGINEER Wildfire 3.0 are a combination of various features that can be modified individually at any time.

Figure B Model after making the modifications






There is a bi-directional associativity between all modes of Pro/ENGINEER Wildfire 3.0. The bi-directional associative nature of a software package is defined as its ability to ensure that if any modification is made in a particular model in one mode, the modification is reflected in the same model in other modes also.

Figure C shows the drawing views of the part shown in Figure A. The views show that the part consists of a counterbore hole at the center and six counterbore holes around it.

Bidirectional Associative Property

Figure C Drawing views of the model before modifications






Figure D Drawing views of the model after modifications

Now, when the part is modified in the Part mode, the modifications are automatically reflected in the Drawing mode, as shown in Figure D.






Figure E Diameter of the hole and the bolt

Figure E shows the Crosshead assembly. It is clear from the assembly that the diameter of the hole is more than what is required (shown using dotted lines). In an ideal case, the diameter of the hole should be equal to the diameter of the bolt.






Figure F Figure after modifying the diameter of the hole

Similarly, if you change the dimensions of the model in the Drawing mode, the modifications will be automatically reflected in the Part mode. This shows that all the modes are related to each other.

The diameter of the hole can be easily changed by opening the file in the Part mode and making the necessary modifications in the part. This modification is reflected in the assembly shown in Figure F. This is due to the bi-directional associative nature of Pro/ENGINEER Wildfire 3.0.






Parametric NatureThe parametric nature of Pro/ENGINEER Wildfire 3.0 means that the features of a part become interrelated if they are drawn by referencing each other. You can redefine the dimensions or the attributes of a feature at any time. The changes will propagate automatically throughout the model. Thus, they develop a relationship among themselves. This relationship is known as the parent-child relationship.

Some important terms that will be used while working with Pro/ENGINEER Wildfire 3.0 are discussed next.

Important Terms and Definitions

• EntityAn element of a section geometry is called an entity. The entity can be an arc, line, circle, point, conic, coordinate system, and so on.

• DimensionIt is the measurement of one or more entities.

• ConstraintConstraints are the logical operations that are performed on the selected geometry to make it more accurate in defining its position and size with respect to the other geometry.






• ParameterIt is defined as a numeric value or any definition that defines a feature. For example, all the dimensions in a sketch are parameters. The parameters can be modified at any time.

• RelationA relation is an equation that relates two entities.

• Weak Dimensions and Weak ConstraintsWeak dimensions and weak constraints are temporary dimensions or constraints that appear in gray color. These are automatically applied to the sketch when it is drawn using the Intent Manager.

• Strong Dimensions and Strong ConstraintsStrong dimensions and strong constraints appear in yellow color. These dimensions and constraints are not removed automatically.






The options that are displayed when you choose File from the menu bar, are discussed next.

File Menu Options

• Working DirectoryA working directory is a directory on your system where you can save the work done in the current session of Pro/ENGINEER Wildfire 3.0. You can set any directory existing on your system as the working directory. Before starting work in Pro/ENGINEER Wildfire 3.0, it is important to specify the working directory, which can be done in two ways.

Creating a Reference Coordinate System

• Creating a Spline

• Splines are curved entities that pass through an infinite number of intermediate points.

• Generally, splines are used to define the outer surface of a model.

• This is because the splines can provide different shapes to curves and the flexibility to modify the surfaces that result from the splines.

Working With Splines

• The Create reference coordinate system button in the Sketcher Toolstoolbar is used to create a coordinate system and add it to the created sketch.

• The coordinate system acts as reference for dimensioning.

To draw a spline, choose the Create a spline curve button from the Sketcher Tools toolbar.






A spline can be dimensioned manually in the following ways:• Dimensioning Splines

• Dimensioning the endpoints

Endpoint dimensioning

• Choose the Create defining dimension button from the Sketcher Tools toolbar.

• Select the two endpoints of the spline and place the horizontal or vertical dimension by pressing the middle mouse button.

• Dimensioning the Endpoints

• Radius of Curvature Dimensioning

• Tangency or Angular Dimensioning

• Coordinate Dimensioning

• Dimensioning the Interpolation Points






• Radius of Curvature Dimensioning

Radius of curvature dimensioning

• The radius of curvature of a spline can be dimensioned only if its tangency is defined.

• In other words, radius of curvature of a spline can be dimensioned only if the spline is tangent to an entity.

• A spline can be dimensioned tangentially.

• This type of dimensioning is also called angular dimensioning.

• Tangency or Angular Dimensioning

• Coordinate DimensioningThe spline can be dimensioned with respect to a user-defined coordinate system.






• Modifying a SplineA spline can be modified in the following ways:

• Dimensioning the Interpolation Points• A spline can be dimensioned by dimensioning its interpolation points or vertices.

• This type of dimensioning is used when the designer wants the spline to be standard for all designs.

• Moving the interpolation points of the spline.

• Adding points to a spline.

• Deleting points of a spline.

• Creating a control polygon and moving its control points.

• Modifying the dimensions of the spline.

• To invoke this button, select the sketch and then choose the arrow on the right of the Mirror selected entities button.

• Choose the Make a copy of selected entities button from the flyout that is displayed.

• The Scale Rotate dialog box is displayed.

• Using this dialog box, you can simultaneously copy and rotate the selected entities.






• The two-dimensional (2D) drawings, when opened in the sketcher environment, can be saved in the .sec format.

• The .sec file can then be converted to a solid model.

• The Data from file option in the Sketch menu in the menu bar is used to import the 2D sketches.

• This option saves time in drawing the same or similar section again.

• The file formats from which the data can be imported are shown in Figure A.

• When you choose Sketch > Data from file > File System from the menu bar, theOpen dialog box will be displayed, as shown in Figure B on the next slide.

• Every model created in Pro/ENGINEER is composed of features that in some way or the other are related to other features in the model.

• The feature that occurs first in the Model Tree is called the parent feature, and any feature(s) that is related to this feature is called the child feature(s).

Parent Child Relationship

This type of relationship exists when the two features are related through equations. These equations are formed using relations.

• Implicit Relationship

• Explicit Relationship• The explicit relationship is developed when a feature is used as a reference to

create another feature.

• For example, one of the planar surfaces of a feature is used to create another feature, or an edge of a feature is used to dimension the other feature.

• In this case, the first feature is called the parent feature and the second feature is called the child feature of the first feature.






• If more than one closed loop is drawn, one inside the other in the sketch of a single feature, it is called nesting of sketches.

• These sketches are drawn in the sketcher environment.

• Figure A shows a sketch in which the two circles are created on the base profile. The resulting solid model is shown in Figure B.

Nesting of Sketches

Figure A Nested sketch Figure B Solid model of the sketch






• Disadvantages of Nesting Sketches• In nesting, since the two features on the model are combined into one feature,

therefore there is no flexibility in editing the features of a model.

• If at a later stage, you need to convert the circular holes into elliptical holes with depth as half the depth of extrusion of the base feature, it consumes a lot of time to edit the model.

• Advantages of Nesting Sketches• One of the advantages of nesting of sketches is that the number of features used

to create a model is reduced.

• There is no parent-child relationship that exists in a nested sketch.

• The depth of the hole is equal to the depth of extrusion of the base feature.

• This is because the two circles and the base profile are part of the same sketch.

• This depends on the whether you want to use the nested sketch to create a part.

Learning Objectives:• Understand the three default datum planes.

• Understand selection methods in Pro/ENGINEER Wildfire 3.0.

• Create the datum planes using different constraints available.

• Create embedded datum planes.

• Create datum axes using the different constraints available.

• Create the datum points.

• Create extrude and revolve cuts.






Datums• Datums are imaginary features with no mass or volume and are

available to help you in creating a model.

• They act as reference for sketching a feature, orienting the model, assembling components, and so on.

• When you enter the Part mode or the Assembly mode, the three datum planes are by default displayed in the drawing area.

• These datum planes are mutually perpendicular to each other.

• These planes are known as the default datum planes.

• To change the names, choose Edit > Setup, the PART SETUPmenu will be displayed, as shown in Figure A.

• Choose the Name option from this menu.

• You are prompted to select a feature to change the name.

• Select the datum plane you want to rename.

• Default Datum Planes

Figure A The PART SETUP menu






Need for Datums in Modeling• Generally, most of the engineering components or designs consist of more than

one feature.

• First the base feature of the model is created and then the other features of the model are added.

• Since all the features of a model cannot be drawn on a single plane, therefore, to draw the rest of the features, sometimes, additional planes have to be created or selected.

• Also, most of the times, the three default datum planes are not enough to create a complex model having many features.

Model having two extruded features

Base feature of the model






The selection method in Pro/ENGINEER 3.0 Wildfire is divided into two types:• Selection Methods in Pro/ENGINEER Wildfire 3.0

• Selection• In Pro/ENGINEER Wildfire 3.0, selection refers to the action,in which you first

select the entities like edge, plane, face, axis, coordinate system, and so on, and then invoke a feature creation tool.

• To make your selection process easier, filters are available in Pro/ENGINEER Wildfire 3.0.

Plane selected for the base feature

Plane selected for the second feature






The Selected Items dialog box

• Filters are the options that are available in the Filter drop-down list located at the lower right corner of the main window in the Status bar.

The Filter drop-down list

• As you select the entities on the model, the number of selected entities appear to the left of the Filter drop-down list in the Status bar.

• When you double-click on the number, the Selected Itemsdialog box will be displayed.

The DATUM PLANE dialog box with the Properties tab selected• Creating Datum Planes

• When you create a datum plane, the constraints are applied automatically based on the selection you make on the model.

• These constraints appear in the DATUM PLANE dialog box.

• Sometimes, while applying constraints to define a datum plane, a single constraint is enough to define the datum plane and sometimes you need more than one constraint to do the same.






Datum plane constraint combinations using the Through constraint

• Through constraint• The Through constraint is used to create a datum plane through any specified axis,

edge, curve, point/vertex, plane, cylinder, or coordinate system.

• This constraint can be used in combination with other constraints that are available in the DATUM PLANE dialog box.

• Properties OptionThis option displays the properties of the hole that you create.

• Preview the HoleThe Feature Preview button is used to preview the hole created before confirming its creation.






Important Points to Remember While Creating a Hole• While drawing the sketch of a hole, the sketch should have an axis of revolution

and at least one entity normal to it.• While creating a hole, the primary reference for the placement of hole can be

selected without choosing any option from the Hole dashboard. However, when you need to specify the secondary references, then you have to choose the Placement tab from the Hole dashboard.

• It is recommended that if you are creating a Standard hole then the units of the model should be in mm.

• An application of Sketched hole is a tapered hole. Sketched holes are always blind and have depth in one direction only.

• You cannot select a convex or concave surface as the placement plane.

• To avoid conflict due to the parent-child relationship, other features should not be referenced to the edges created by rounds or to the round surface.

• Points to Remember While Creating Rounds

• Rounds should be added at the last. This means, the rounds should be the last features in any solid model.

• The regeneration time of the model increases if the number of round features is in it are increased.

• Use the shortcut menus extensively while creating rounds to reduce modeling time.






Creating Chamfers• Chamfers are used to bevel the selected edges and corners as per some

specified parameters. Pro/ENGINEER creates two type of chamfers.

• The first is the Corner chamfer and the second is the Edge chamfer. To create a chamfer on a corner, choose Insert > Chamfer > Corner from the menu bar.

• To create a chamfer on an edge, choose Insert > Chamfer > Edge from the menu bar.

• You can also choose the Chamfer Tool button from the Engineering Featurestoolbar to create the edge chamfers.

• The Flip button is used to flip the side where the material should be added.

• This button will be available only when you draw the sketch and exit the sketcher environment.

• This button is available on the Rib dashboard only when the sketch of the rib is drawn and you exit the sketcher environment.

• You have an option to extrude the sketch on either sides of the sketching plane or symmetrically to both sides of the sketching plane.






Editing Features of a Model• Editing is one of the most important aspects of product design.

• Most of the designs require editing during their creation or after they are created.

• As mentioned earlier, Pro/ENGINEER is a parametric and feature-based solid modeling software. Hence the features constituting a model can be individually edited.

• The six counter bore holes are converted into eight countersink holes in the figures shown below.

Six counter bore holes Eight countersink holes






• Editing Definition or Redefining Features• Editing the definition of features allow you to make changes in the parameters

that were used to create it.

• You can also modify the sketches of the sketched features by editing their definition.

• A feature is redefined only when it is completed.

• Reordering Features• Reordering the features is defined as the process of changing the sequence of

feature creation in a model.

• Sometimes after creating a model, it may be required to change the order in which the features of the model were created.

• A feature can be placed before or after another feature.

• For this purpose, the Model Tree or the FEAT menu is used.






The FEAT menu The SELECT FEATsubmenu

The REORDER submenu

Model with pattern Model after creating the shell feature

Model after reordering the features






• Rerouting Features• The References option available in the Edit menu is used to modify the

references of a feature and in turn break the parent-child relation that exists between the selected feature and the other features.

• The rerouting of features is done using the References option.

• Suppressing Features• When you do not want a feature to be displayed in the drawing area or to

show up in the drawing views of a model then that feature can be suppressed.

• Once the feature is suppressed, it will neither be displayed in the drawing area nor in the drawing views.

• Deleting a Feature• The feature that is not required can be deleted from the model.

• Right-click on the feature in the Model Tree or in the drawing area to invoke the shortcut menu.

• From this menu, choose the Delete option.






• Modifying a Feature • Once a feature is created, you can still modify it by modifying its dimensions.

• This editing operation reflects the parametric nature of Pro/ENGINEER.

• Right-click on the feature in the Model Tree or in the drawing area to invoke the shortcut menu.

• From this menu, choose the Edit option.

• The dimensions are displayed in the drawing area. Double click the dimension to be modified and type the required value in the edit box that appears.

• Dynamically Modifying the Sketch of a Feature• If you want to modify the sketch of a feature without entering the sketcher

environment, then you need to modify it dynamically.

• Select the feature in the drawing area using the left mouse button.

• The selected feature is highlighted in red, hold down the right mouse button to invoke the shortcut menu. From this menu, choose the Edit option.

• The selected feature is highlighted in red and the dimensions appear on the feature.

• Use the Mirror option.

• Use the Mirror Tool button.

• Create section of a model.






Creating Feature PatternsPatterns are one or two dimensional incremental array of features created from a single feature called the parent feature or the leader. When a pattern is created, the leader also becomes a part of the pattern.

• Patterns create multiple copies of a feature, and therefore, save time that would otherwise be spent in creating the features individually.

• Uses of Patterns

• All instances in a pattern, including the parent feature, act as a single feature. Therefore, they can be easily suppressed or mirrored.

• All instances in a pattern are related parametrically. Therefore, you can modify the number of instances in a pattern, the spacing between the instances, and other pattern related parameters.

• If the dimensions of the parent feature are modified, then the dimensions of the child features are also modified.






• Creating Patterns

The Drop-down list contains the various types of patterns. There are seven types of patterns that can be created in Pro/ENGINEER.

The Pattern dashboard

• Dimension pattern

Learning Objectives:• Understand the top-down assembly approach.

• Understand the bottom-up assembly approach.

• Assemble the components of the assembly using the assembly constraints.

• Understand packaging of components.

• Create the simplified representation for viewing various components of assembly.

• Use the View Manager.

• Edit the assembly constraints after assembling.

• Modify the components of the assembly within the assembly.

• Create the exploded state of the assembly.

• Add the offset lines to the exploded components.

• Understand the Bill of Material in the assemblies.






Assembly Modeling• An assembly is defined as a design consisting of two or more components bonded

together at their respective working positions using the assembly constraints.

• These assembly designs are created in the Assembly mode of Pro/ENGINEER.

• To proceed to the Assembly mode, choose the Create a new object button from the Top Toolchest.

• The New dialog box will be displayed; select the Assembly radio button from theType area and then select the Design radio button from the Sub-type area.

• Specify the name of the assembly in the Name edit box and choose OK.

Selecting the Assembly mode from the New dialog box






Initial screen appearance of the Assembly mode






Important Terms Related to Assembly Mode• Top-down Approach

This is the method of assembling the components in which the components of the assembly are created in the same assembly file and then assembled using the assembly constraints.

• Bottom-up Approach• This is the method of assembling the components that are created as separate

parts in the Part mode and are saved as .prt files.

• Once all the parts of an assembly have been created, you will create a new assembly file (.asm) and then assemble the parts using the assembly constraints available in the Assembly mode.






• Remember that if any of the assembly component is moved from its original location on the hard disk, the assembly will not open the next time.

• This is because Pro/ENGINEER searches for the assembly component in the folder in which it was originally saved.

• If it does not find the name of the component in that folder, it gives an error while opening the assembly file and the RESOLVE FEAT menu will be displayed.

• Choose the Quick Fix option from this menu, the QUICK FIX submenu will be displayed.

• You can use the options in this submenu to locate the part file.

The RESOLVE FEAT menu

The QUICK FIXmenu






• PackageIt is the state in which the component that is being assembled is not fully constrained and therefore is not rigidly placed at its actual location.

Creating Top-Down Assemblies• As you know, to create components you need the sketcher environment and to

invoke the sketcher environment you need the Part mode.

• You can invoke the Part mode from within the Assembly mode and create components using the tools in the Part mode.

• Placement Constraints• The placement constraints are the constraints that are used to rigidly bind the

components of the assembly to their respective positions in the assembly.

• These constraints are also called the assembly constraints.






• Creating Components in the Assembly Mode

The Component Createdialog box

Creating Bottom-Up AssembliesWhen the first component is inserted in the Assembly mode, its three default datum planes are placed in the same orientation as that of the default datum planes of the Assembly mode.

• In Pro/ENGINEER, you can also create components in the Assembly mode.

• The components that you create in the Assembly mode are saved as separate .prtfiles.

• To create a component in the Assemblymode, choose the Create a component in assembly mode button.

• The Component Create dialog box will be displayed.






• Inserting Components in Assembly

Placement ConstraintsThe placement constraints are also called assembly constraints and are available in the Component Placement dashboard, which is discussed later in this chapter.

• AutomaticWhen you choose this constrain, Pro/ENGINEER assumes the constraint and applies it according to the type of entity selected.

• When you choose the Add component to the assembly button, the Open dialog box will be displayed.

• Select the part that you need to insert in the assembly.

• After the component is displayed on the drawing area in the Assemblymode, you need to specify constraints in order to assemble them.

• Even if you are placing the first component, you need to constraint it using the assembly constrains.






• MateThe Mate placement constraint allows you to make two selected planes, datum planes, faces, or a combination of datum plane and face coplanar with respect to each other.

• If you need to keep the two faces or planes at some distance apart, then you can use the Mate constraint with some offset value.

• Figure A shows the faces that are selected to apply the Mate Offset constraint.

• Figure B shows the component assembled at an offset distance from the selected face.

• Mate Offset

Figure A Components before assembling

Figure B Components after assembling






• The Mate Coincident combination of constraints allow you to make two selected planes or surfaces coplanar to each other.

• Figure A shows the faces that are selected to mate. Figure B shows the components after assembling.

• Mate Coincident








• The Mate Oriented combination of constraints is used when you want to mate two faces or planes or a combination of two and at the same time you want to orient some other faces or planes of the two components to face in the same direction.

• Figure A shows the faces that are selected to mate and Figure B shows the components after assembling.

• Mate Oriented








The Align constraint is used to assemble two components by making the selected faces or planes coplanar such that the aligned faces or planes are facing in the same direction.

• Align

Figure A Components before applying the Align Offset constraint

Figure B Components after applying the Align Offset constraint

• The Align Offset combination of constraints used to align two entities with some offset distance between the aligning entities. The offset value can be positive or negative.

• Figure A shows the faces to align offset and Figure B shows the components after applying the constraints.

• Align Offset






• Align Coincident• The Align Coincident combination of constraints is used to assemble two

components by making the selected faces or planes coplanar such that the aligned faces or planes face in the same direction.

• Figure A shows the faces that are selected to align. Figure B shows the components after assembling.

Figure A Components before applying the Align Coincident constraint

Figure B Components after applying the Align Coincident constraint






• Align Oriented• The Align Oriented combination of constraints makes the two selected faces or

planes or the combination of both, face in the same direction.

• Figure A shows the constraints applied on the two components and Figure Bshows the two components after applying constraint.

Figure A Components before applying the Align Orientedconstraint

Figure B Components after applying the Align Oriented constraints






• The Insert constraint is used to assemble the revolved components.

• Applying this constraint allows the revolved component, holes, or a combination of both to share the same orientation of the central axis.

• Figure A shows the faces to insert and Figure B shows the components after assembling.

• Insert








The Coord Sys constraint aligns the coordinate system of the first component with the coordinate system of the second component.

• Coord Sys

• TangentThe Tangent constraint is used to make the selected circular face tangent to the other selected face or plane and at the same time make them coplanar.

• Pnt On LineThe Pnt On Line constraint is used to align the selected datum point or the vertex on the first part with the selected edge, datum axis, or datum curve on the second part.

• Pnt On SrfThe Pnt On Srf constraint is used to align the selected datum point or vertex on the first part with the selected surface or datum plane on the second part.






The Edge On Srf constraint is used to align the selected edge of the first part with the selected surface or datum plane on the second part.

• Edge On Srf

• Default

• Fix

The Default constraint is used to assemble the component in the assembly by aligning the default coordinate system of the component with the default coordinate system of the assembly.

The Fix component to current position button packs the two components and displays that the two components are fully constrained.






Assembly Datum Planes• When you enter the assembly environment, the three datum planes are

displayed in the drawing area.

• If you do not want the default datum planes in the assembly file, then while opening a new file, you need to clear the Use default template check box that is available in the New dialog box.

• It is recommended that you use the assembly datum planes as the first feature of the assembly and assemble the components of the assembly taking the reference of these assembly datum planes.






Assembling the Components• The components in the assembly can be placed parametrically or non parametrically.

• If the components are placed using the placement constraints, it is called parametric assembly.

• If the components are packaged, it is called nonparametric assembly.

• To assemble the components parametrically, choose the Add component to the assembly button.

• The Open dialog box is displayed.

• Once you select the part to assemble from the Open dialog box, the Component Placement dashboard will be displayed.

• The options in the Component Placement dashboard are discussed next.
