for posting letters!!! hehhehe sorry could'nt resist






an example of it would be to consider a square block moving around in a circle. the motion envolope would be a ring.



you use motion envolope's in mechanism.

basically once you have your mechanism and want to see the exact(
approximated actually ) path of travel then u create a motion envolope
of that part. you can then adjust for clearances and what
have you. for simple shapes you can just use you brain and come up with
a motion envolope in your mind. but for complex 3d geometry it really
helps.



you can save this envolope as a part. and give it to someone working on
a assembly and then tell them to keep that volume clear of any
obsticals.



hope this helps.

Not only,envelopes are part of Top-Down design methodology in Pro/ENGINEER.


They great tool for large assembly management. You can use then to simplify and lighten your large assembly and you use them in simplified reps ...
