I recently received a zip folder containing several file types for a hydraulic hangar door system. I looked up the best ways to convert the step file, sat file and x_t file. Most everything I came across suggesting converting it to an STL file and then importing it into archicad, however importing a step file via FreeCAD and exporting it as a STL file changes the file size from 2MB to 82.7MB. Apparently it causes a lot of issues with archicad and I haven't been able to reduce the file size successfully yet. Is there a way to just import a step file as an object or reduce the STL file without drastically distorting the mesh? I've tried Meshmixer but I can't find a tutorial on how to reduce without breaking the object. Any help would be appreciated!
