I'm new to simscape. We have independently created CAD parts that we'd like to model their interactions in Simscape. We've imported each STEP file but are running into a problem. The interaction works fine if we don't have gravity on. When we add gravity to the model a few parts fall through the main structure. To infinity and beyond it seems. I did not perform the import so I'm not sure exactly how it was accomplished. I do know they original parts came from Inventor.
So even though visually there are constraints we don't seem to have them in the model. The simscape documentation only shows importing a full assembly of parts.
What do we need to do to add the surface constraints to the step file blocks so they don't interset each other.
