MDX/MDO motion analysis feature: learn mechanism collision position from results parameters?

Hi,

I have an assembly containing a mechanism and its environment and I want to create a motion analysis study using the MDX/MDO features which allows me to automically detect a collision during a certain kinematic analysis. I created position-type measures on my motion axes in the mechanism module which tell me the positions of my bodies and I've enabled the collision detection settings with the option "stop when colliding" on. My idea was to use the measures in the motion analysis study to tell me at what position the interference is occuring but the problem is that the study is not stopping at the collision (but it is detecting it!). Because it is not stopping I'm not able to lean this position from the model. Does anybody have experience with such a study? When I enable collision detection the study creates a new parameter called "COLLISIONS_DETECTED:MDX" and "COLLIDED_PARTS_LIST:MDX" and these parameters work indeed even if the study continues after the collision.

Sam, you may be interested in voting on the following product enhacement idea

Mechanism Clearance Check with Spatial Field Point Reporting (highlight on/in parts where clearance needs to be added & how much needs to be added)

Which does basicly the same thing your trying to do but for multiple postions where contact may occur or a specified distance  between parts is violated. The results of this enhancement could be used in a optimization analysis too.
