Issue: STL parts in an assembly separate when 3D printed I have made several models in Creo supporting our FIRST Robotics team. I've noticed on many occasions, that when I print these (Fusion F306 printer or others), the models often separate along the intersection boundaries of where one part has been placed inside another for the combined Assembly. For example, in the Panda bear screenshot below, the legs will print as posed, but separate easily along their original part lines when the model is handled. I believe the cause is that the triangles defining each part don't merge into one another for a true solid model assembly.For a better assembly, I would love to apply a fillet or other material, or perform some operation that "merges" or stitches these parts into 1 solid mass. We are certainly getting good parts, using the "solidify" command during creation, and passing the model inspection tools. When I print parts alone (not assemblies), they come out just fine, even when they involve several intersected primitives
