On a planarface of a part that was previously

constructed Look for face selection icon:

Reference PlanesHint

Rename planesto be more

descriptive than

Plane1, etc.

Mechanical Design

1. If you can buy it

dont make it!

2. If you can download it

dont model it!

Complex Lofts

Lofts may have multiple profilesand multiple guide curves

Take advantage of symmetry Half body mirrored about centerplane to form complete body

Extruding Solid Objects

In order of increasing capability/complexity

Boss-extrude

Constant cross-section

Single direction (sketch

plane)

Sweep

Constant cross-section

Single 3D guide curve

Loft


Varying cross-section

Multiple 3D guide curves

All of these features can create cuts

Shell Feature Useful for injection molded plastic parts


1. Modelas solid

2. Cut inhalf

4. Add ribs,swept cuts

3. Shellout half

Deform Features

Flex


Twist

Patterns

Linear or circular patterns simplify creation of

multiple features


Circular Pattern

Linear Pattern


Can pattern in twoorthogonal directions

Building a Complex Model1. Model half groove


2. Mirror about center plane3. Linear pattern 125X4. Add remaining features

Sheet Metal Bends Increase Stiffness

Bending up the edges of this thinplate a small amount increases itsbending stiffness nearly 7 times


Measurement Section propertiesArea, centroid location, area moment of inertia


Measurement Volume, mass properties


Configurations

Allows the creation of families of parts
