Hi Rado, the parallel viewport in MoI will use what is called an orthographic projection, but it seems that the kind of thing that you want does not fit under the category of orthographic projections.

I'm not sure if you will be able to find a CAD program that would automatically generate that kind of projection that you are looking for, since I think it will produce a lot of distortion in any curved pieces.

I think that usually drawings like that are done with 2D drawing tools only, rather than taking 3D model data as input.
