Dear Max, Victor, Thanks a lot for your prompt replies! And yes, your suggestions were both right. With Gmsh 4.3 I can obtain what I want. I was not using the most updated version of Gmsh because my code cannot handle the newest mesh format at the moment, but now I have found I can still use the 2.2 format by setting Mesh.MshFileVersion=2.2.
Thanks again for your help!

Here is an earlier thread about the same issue if you need more info: http://onelab.info/pipermail/gmsh/2019/012965.html Max On Tue, Apr 23, 2019 at 5:24 PM Marco Tiberga <[email protected]<mailto:[email protected]>> wrote: Dear Gmsh developers, I want to create a mesh from a STEP file, loading it from a geo file. The mesh should be in m (as you can see from the step file, line 2916) , but from the numbers I visualize in gmsh, I deduce the lengths are still expressed in mm (the entire domain should be around 2.5m high, but I see 2500). How can I perform the units conversion? I tried with factor = 1.e-3; allpoints[] = Point "*"; Dilate{{0,0,0},{factor,factor,factor}}{Point{allpoints[]};} but it does not seem to work. I attached the .geo and the .stp files I am using. I use Gmsh 3.0.6. Thanks a lot for your help and sorry if the question is stupid, but I have little experience in using gmsh with step files.
