I was trying to print two overlapping stll files in Simplify3D, but only one file came out the slicer.
Did I do something wrong or is it not possible to combine stl files within Simplify3D?
If not, any suggestion how it could be done is welcome.
This is not strictly true, and I think Carl has forgotten the new Separate Connected Surfaces option (on Mesh dropdown) that was introduced in v3. I have the issue of separate meshes in the same stl file all the time as my 3D CAD package is not that good at Boolean logic. Using the option actually separates the meshes out and creates multiple models from them. And S3D does the rest by merging the meshes before slicing.What you cannot do is have 2 meshes that are shoved together into the SAME single STL file with lots of overlapping and self-intersecting surfaces. That won't work, because you have told the software that is a single model, but in reality, it is not.
