Creo Parametric - Assembly Mechanisms - Motion Envelopes

[@rorybowcott]

Are you able to replace a sub-assembly in a top level assy with the motion envelope? I know you can replace sub-assemblies with an envelope but I can't figure out how to get the motion envelope.

Hey Dave, have you ever heard or scene any issues with CREO 8 and, Mechanism 3D Contact surfaces? I am trying to animate a chain and sprocket. I created contacts between the sprocket surface and the roller surface. The sprocket and chain are sync for a second then, the sprocket keeps moving without taking the chain with it. Thanks.

I have not. But I haven’t used 3D Contacts in years. (Only because I have not had a need.) I recommend contacting PTC Tech Support.

not related to the motion envelopes, but to mechanisms in general, how would you properly make Bender to move one arm 360 deg with a certain velocity/acceleration profile and when that motion is finished, a second arm would move 360 deg (one motion after another)? Thanks!

In analysis menu, you have the option to change start and stop time of motors 1 and 2. Use thay.. run the first motor arm from start to 10 seconds and for next motor arm give 10 at start and then End.
