Hello,

I have a model in which my arm lever should move follows a 3D profile of my rotary cam. If I want to model this in Adams, I believe the best method to use is the point-curve constraint. My model consists of imported parasolids, and I am using Adams Student Edition 2011.

I am having a few issues:

First, when selecting an edge, I can only select one edge. My parasolid consists of several edges all the way around, so my constraint is valid only for a few degrees of revolution before contact with the next edge is needed. Is there a way to concatenate edges or specify multiple continuous edges in a point-edge constraint?

Second, I have 2 edges that define the path of the cam follower. However, to get the correct path, I need the point to follow a curve at the midpoint of the two edges. I have had trouble importing edges defined in Design Modeler and SolidWorks, so I need a way of specifying the center-line path. Have others had issues with importing lines?

Are there any suggestions/preferred methods for using a point-curve constraint (or any other joint/constraint) for a rotary cam and arm lever follower?

Please see my attachment for details...Really need your help!!

Thank you.

Hilmi
