I'm using Solidworks to design parts to be 3d-printed.
I've noticed that if I'm making an assembly, where one part has features that touch other parts, then when I try to save that assembly as an STL for printing, I'll get a dialog from Solidworks saying "This assembly has coincident or interfering geometry that may be unsuitable for some rapid prototyping systems." If I save it, then this STL later causes problems when trying to print it.
What can I do? I'd like to be able to print my assemblies.
Here is a very simple example assembly where you can see this phenomenon. Part 1 is just a simple cube, and part 2 is another simple cube that is flush with part 1.
