Open discussion Have some feature requests, feedback, cool stuff to share, or want to know where FreeCAD is going?
First post here, I'm rather new to FreeCAD AND Python so this is quite a challenge for me. I am writing a script that takes a 3D model and will generate 2D CAD Views of each part of the model. End goal I want to also add a leader line pointing to the part and annotated with the part name and part #.

If you get the drawings from your friend in some 2D CAD format (dwg, dxf, etc), it'll be fairly easy to model on top of it (check the Arch tutorial). If there is a 3D model already, even in mesh format, it's even better, but be aware that architecture models are not always very precise in their dimensions.
So far, the FreeCad arch workbench tutorials I find on YouTube show people drawing arbitrary structures, not the practical task of drawing a plan from field notes. Often as-is plans need to be correct to the nearest inch or less in order to be useful. There is no guidance on how to accomplish such precision using the gui interface.
So I am fairly new to CAD software, and FreeCAD is the first CAD program I have ever used. I have gotten my model into the part design workbench, and now I want to add the dimensions. I am wondering, though; is there a way to automatically generate and label the dimensions of the model, or do I have to do each one manually with the "Measure ...
Brep “true” reports are non-computable since the machine cannot know the purpose of our drawing. I have looked over a number of different approaches to the problem of deriving x,y, z views from perspective drawings. It’s a fact that FreeCAD and other programs have no difficulty in giving us a perspective view of an x,y, z drawing.
Similar to 2D, where programs like Paint are stunningly easy to use while vector oriented programs don't seem to be that intuitive on first sight, we face a similar situation in 3D. The idea of parametric modeling is - yes, the name suggests it - to manipulate the parameters and everything follows.
A simple test drawing (in the application). I can't get rid of some things: 1) Why does the Report window in FreeCAD always show Check milling spindle number: Txx and Check milling spindle number: Txx, even if TOOL_NUMBER >12 if I put it in the condition: if command in('M6', 'M06'): if TOOL_NUMBER <= 12: #add height offset
IMO, direct modeling for CAD doesn't make since, it's fine for graphic editing programs but not CAD. The goal of CAD is to associate the solids to drawings and the designer is responsible to keep those two things in lock-step. You can waste money and time not mention your job and reputation if the wrong parts are manufactured.
