scroller2149,
If you have the BMX module, this is pretty easy. You will want to create an analysis feature that measures the distance between the two parts of interest (if you accept the default names, this will come out to be DISTANCE:FID_ANALYSIS1). Then, I would create a second analysis feature that is relation to calculate an error function (ERROR = DISTANCE:FID_ANALYSIS1 - 3). Then you can use a mechanism analysis feature and pass the ERROR:FID_ANALYSIS2 parameter through it. The mechanism analysis feature can output the minimum value of the simulation. You can now have the clearance parameterized as the design evolves.
Hope this helps!
Best regards,
Matthew Ian Loew
