Re: TechDraw: Why do dimensions have to be manually linked for isometric views?
TechDraw uses the OpenCascade function HLRBRep_Algo() , which is called 'hidden line removal algorithm', to project the 3D geometry to the 2D drawing. On many other functions OCC supports a "history" so you have knowledge of how your output shapes relate to the input shapes. Unfortunately,...

Re: Missing edge in projection
With the help of https://forum.freecadweb.org/viewtopic.php?f=10&t=47017 and the offical OCCT documentation, I was able to compile OCCT 7.4.1-devel and start env.bat vc14 64 debug and then DRAWEXE.exe. (The "debug" is necessary otherwise it will not set the correct path to the debug bi...

Re: Missing edge in projection
Thank you for your nice explanation and work-around! I still wanted to file a bug for OCC. I think OCC also wants a minimal example of the bug, so I had to find out with what parameters OCC functions are called. So I set up a build environment an succeeded in 2 hours to compile a debug version of Fr...

Re: Missing edge in projection
I simplified the file down to a minimal example of the problem, so a bug could be filed for this. I think this is a shortcoming in FreeCAD that can drive new users crazy. I don't want to sound too negative, but I think it's a cardinal sin for a CAD program to require the user to change his mechanica...

Re: scaling issue for balloon and leaderline
[...] You can try to reset the configuration [...]. Another possibility is to delete your config files [..]. Thank you, that fixed problem #1. I feel a little humbled, because i should though have about that myself first. Dragging the balloon text moves the bubble, ctrl + drag on the label moves th...

Re: Import ACIS .sat files into FreeCAD?
I found this project that that says "SAT and SAB files can also be imported into FreeCAD", but it seems only in Inventor files. So maybe this could be adapted to read just the bare .sat files. https://github.com/jmplonka/InventorLoader (I know, this is an old thread, but it's still the fir...

Re: scaling issue for balloon and leaderline
Let me hijack this thread for my issue: The defaults for the balloon tip are broken for me. The balloon tip is larger than a A4 page size in my test. Step to reproduce: Start a new document. Part Design: create new sketch and draw a circle and constrain it to 10 mm. Exit sketch and pad to 10 mm. Cre...

Re: Geometric Dimensioning & Tolerancing
I don't know if you are aware that there is an older GD&T toolbox. Maybe you can use some code from the other toolbox to make your life easier.
