alt Hacker NewsNo decent engineering firm is going to want to work with FBX or Blender files. In fact they probably wouldn't even know what to do with them. Even proper model formats such as STEP files don't give you the details that are on a drawing that you actually need to do anything useful with these.
I’ve only dabbled with cad for 3d modelling in Onshape. It seems that there all kinds of ways to add measurements in the render files. Not sure about blender.
