I have been using 3MF and seriously considering STEP format as from what I see and understand, rounded surfaces are cleaner when printed. Sadly I find less people are downloading my files when they are on that format compared to STL. I find different and sometimes conflicting informations about those file formats. Some stating malicious G code can be inserted in 3MF. So I’m really having a hard time finding the right information in clarifying it so explain the why of the benefits of 3MF and STEP aside from the file sizes and quality advantages.

Is it true of those malicious codes can be inserted of is it a myth. I design 3D terrain for tabletop gaming, self taught, so I don’t have the benefit of proper education on the technical file format technical aspect.

Hey I have stl files can they be converted into stp files

A .stp or .step does not contain full parametric CAD data, as there will be NO individual features upon import!!! Although it will contain complete surfaces such as a hole will not be segmented into lines and facets.
