Most Efficient CAD Format

Hello there!

Can someone provide some input on which CAD file format would allow for most efficient use of processing time? (If it makes a difference at all?)

Our CAD files are usually in SolidWorks, however we are wondering if it’s better to upload as STEP for example.

SimScale support a lot of CAD formats like IGES and STEP, but STEP/STP format is most compatible and recommended. if you are in Architectural Engineering and Construction industry (AEC) you can use STL format since its widely used in AEC industry. and also you can import directly from native CAD format like Onshape, Autodesk and Rhino.




In addition to what @Anware said it is also possible to upload assemblies in compressed archives (*.zip, *.tar.gz). Find a list of the supported file extensions below:

*.sldprt SolidWorks part
*.sldasm SolidWorks assembly (in compressed archive)
*.ipt Autodesk Inventor part
*.iam Autodesk Inventor assembly (in compressed archive)
*.3dm Rhino part
