I am actually wondering just as what I type in the subject "HOW to make part family spin over a certain axis?"
Here is the thing that I want to do,
I want to make two parts in the family, according to the datum coordinate, I want to make another part which is exactly the same part as this is, but it spins 180 degree over Z-axis. Do you guys have ideas on how to work this out?
Solved! Go to Solution.
Define a angle expression. Create new feature using 'Move object' command where you can select the rotation about z axis and use the defined angle expression as it's value. In part family excel use this expression where you can vary it's value to control orientation of geometry in child parts as per your requirement.
Any specific purpose for this requirement? As you will add PF member to an assembly, it can be constrained/oriented the way you want.
