Approach 3

Sweep Cut


21/78


Approach 3

SWEEP CUT STRATEGY

P. 21

Create a new surface which is to be"SWEPT" down a newly defined line

Use the "SWEEP" function with the "CUT"option to remove the desired material


22/78


SWEEP - CUT

P. 22

Assume you want to cut off the corner as shown,

but do not want to affect the portion protruding

to the right of the object below. Using a work

plane and the split will cut into that protrusion

since the work plane "goes to infinity".


23/78


P. 23

Define plane to sweep

1.) Create a new sketch plane

on the top of object

2.) Draw 3 line segments to

create a closed surface and

properly place the end pointsusing dimensioning

You now have defined the closed

surface that you are going to

"Sweep"


24/78


Define path of the sweep

P. 24

3.) Create a new sketch plane

on the front of object

4.) Draw a line which is coincident

with the end point of the surface

to be swept and terminates atthe boundary of the protrusion.

You may use either project

geometry and a coincident

constraint or dimension the line

to correct position.

You now have defined the paththat you are going to "Sweep"

5.) Finish sketch


25/78


7.) Select the profile

which is to be swept

SWEEP - CUT

6.) Click on Sweep

8.) Highlighting will now move

from the "Profile" button to

the "Path" button

P. 61

Changing ISOMETRIC ORIENTATION

PROBLEM:

Your Inventor Part is not ORIENTED as

desired either because you started yourinitial sketch on a less than optimal plane or

the orientation was accidently changed

during the design process


62/78


P. 62


You hit F6 and get

this orientationThe reoriented view

Then right click

on ViewCube

and select SetCurrent View

as Home-Fit to

View

Left click on upper right

corner of ViewCube

Use the View Face feature in the

Navigation Bar to select the

desired FRONT face

Right click on ViewCube

and select Set Current

View as Front


63/78


P. 63


NOTE: If you have reoriented your object and that

reorientation is different from you initial assignment

and you leave the object in the ISOMETRIC VIEW

before you create the BASE VIEW in the DRAWING by

using the FRONT (XY), your object will be oriented as

it was ORIGINALLY CREATED. This is illustrated on

the following slide as well as a method to get the

desired NEW orientation into your DRAWING.


64/78


P. 64


Original Orientation Reoriented

FRONT &

HOME VIEWA

ssume you leaveyour Reoriented Part

in the ISOMETRIC

VIEW as shown to the

to the left and then

create a BASE VIEW

in your DRAWING

using the FRONT(XY)

selection

Then you will produce aDRAWING oriented as

shown to the right with

the triangle at the top

(matches the Original

Orientation)

as shown in previous slides


65/78


P. 65


But if you leave your

Part in the FRONT

VIEW as shown to the

to the right and then

create a BASE VIEW

in your DRAWINGusing the CURRENT

selection

Then you will

produce aDRAWING oriented

as shown to the right

with the triangle at

the side

and thePROJECTED

VIEWS will have

the triangle

oriented to the

side!

Restoring Lost Geometric ConstraintsPROBLEM:

You notice that INVENTOR is no longer applyinggeometric constraints AUTOMATICALLY to yoursketch. This has probably happened just afteryou attempted to apply either a "Coincident" or"Parallel" or "Tangent" constraint and youaccidently clicked on either the adjacent"Constraint Inference" or the adjacent"Constraint Persistence" box. ( next slide )

P. 75

Fi t Y E i i P


76/78


Restoring Lost Geometric Constraints

P. 76

The default state for both ConstraintInference and Constraint Persistence is

"ON" so that, while sketching, geometric

constraints are AUTOMATICALLY applied

by INVENTOR. "ON" is indicated by the

BLUE background color as shown below.

In this default state, turning on "Show All

Constraints", the applied constraints are

displayed as shown below.

Fi t Y E i i P


77/78



P. 77

If the default state for both Constraint Inferenceand Constraint Persistence is changed to

"OFF" , no constraints will be AUTOMATICALLY

applied by INVENTOR. "OFF" is indicated by the

WHITE background color as shown below.

In this "OFF" state, turning on "Show All

Constraints", there are NO applied

constraints to be displayed as shown

below.

Fi t Y E i i P


78/78


INVENTOR will then AUTOMATICALLYapply geometric constraints on any new

sketch features ( note boxes color change ).

One should then remove any portion of the

sketch without constraints ( this is the

easiest solution ) or apply geometric

constraints manually.


P. 78

To restore INVENTOR to it's default state,

left click on Constraint Persistence as

shown below.
