Comparing the STL files generated by OpenSCAD 2021.09.09.ci8596 to previous versions I have used, nearly all the STLs vertices are slightly different. Usually it is just the last significant digit change by one, but sometimes 2 as in the second vertex of the second loop here. [image: image.png] Is this expected, what has changed?

Linear extrude with twist has seen improvements but I would assume those cases would generate a more different result. ciao, Torsten.

None of my library printed objects include text. The example was just a simple rubber foot created with rotate_extrude(). https://github.com/nophead/NopSCADlib/blob/master/printed/foot.scad#L49 Probably not a big issue but I publish STLs on github, so I notice if any change.
