I am new user of tecnomatix (v13.0.2). This is my fist topic on this community and I hope you will be good to me.
I created a compound resource and created robot and rail system in it. Robot is attached to the carrier of the rail system. Rail system kinematix has a to link (base->carrier). while simulation is being playing, when collision mode on, collisions are taken place between attached objects.
If you open the Collision Viewer, you may observe that you have an option to create "Collision Sets".
Each such set has a "left" and "right" list.
Objects in the same list will not be tested for collision, so you can create a collision set with the robot & rail on the left list, and whatever else you want to check collision with on the right list.
