On Win7, using 3.2.21 with stl files used previously (below) in V 21.08 without scaling now requires scaling by 100000%.
@Thad Thank you for the report, and sorry to hear about the issue.
Attempting to duplicate here, it appears there may be an issue with the automatic "scale small models" option. Checking on it, it also looks like it is working on our 2.6 branch, and may have been an issue when merging 3.2 from upstream.
We will look into it, and see what we can do to get it fixed up for future releases.
