There was a bug in the beta with scales of 3D models. We have fixed it in codes.
We plan to add scale factor for VRML output. We export 3D models in millimeters now, but some CADs read VRML file in meters. So scale factor will fix the problem.
We planed to implement export to STEP but it is very complex format and we haven't enough documentations. Then we decided to implement export to VRML because it is easier and supported by many CADs. But we may add export to STEP later.
Thank you. I'll wait for the next beta with these bug fixed (if you need an active betatester, i'm here!).
Good bye and good work!
p.s. i know i asked you before, but what do you think adding resize to libraries toolbar, and an option to schematic to be able to link a wire to net with an arrow (same as "add to net" of components' pin) ?
