Step export file size increases compared to import

Has anyone else noticed this?

I imported a 16mb STEP file.

I then removed a few blocks from it.

When exported from Rhino, the resulting file was 36mb large…

Hi @eobet
Often there’s a lot of other info saved with the Rhino file - things like data from plugins, textures, environment and the main culprit when it comes to files size: render meshes. If you SaveAs and choose Save small and don’t save textures and plugin data, the file size will probably get smaller. Still, there’s a still a big diffrence in just how much the various formats can compress the same geometry. Rhino, I think, is not compressing the data much.

“Save small” doesn’t seem to have an effect on STEP file exports…
