Exercise 2
Previous: Chapter 8 | Next: Chapter 9
This exercise teaches how to assign materials. You will also learn how to create a custom material and save it to a custom material database.
Ensure units are set to mm on the Geometry branch of the Design Study Bar.
Autodesk® Inventor, PTC Creo, and Solidworks:
Units should already be mm. No action required.
UGNX:
Right click on the Geometry branch.
Select mm.
Click Materials on the Setup tab:
