![]() ![]() Millions of users download 3D and 2D CAD files everyday. Have been using Cadence orCAD/Allegro for ages even before Cadence introduced STEP-file mappings and display but I have not encountered STEP-files that are several hundreds of MB in size. Dassault Systmes 3D ContentCentral is a free library of thousands of high quality 3D CAD models. It was a 58MiB Step file, I opened it, concluded it looked nice and then deleted it again. I once wanted to add a 3D model of an RJ-45 connector. End quote - I made a variant that doesn't have all the small parts, and export that. There should be a way to optimise a STEP file but I never found a tool that could. Even Solid Works can't handle a 600MB step file. It produces huge step files even without including the PCB traces. I have a similar problem with Orcad Allegro. Their expensive tools took hours to open and process the STEP files that came from Altium. ![]() But I had similar feedback of exported PCBs from other Mech. Though I was only opening STEP files that are maybe 50MB or less.
