I am amateur at CAD, shapr3D is the first and only tool I can use, now I need to make 2D perspectives but I have to work this out in other CAD software, as a Mac OS user this is not easy for me. So it would be very amazing if I can do this directly in Shapr3D!
There’s a workaround until we implement dxf export for bodies in the current view.
When you are done with your design, create construction planes around it. Try to position them in a way like their normal vector would be your camera vector. Now, go to project tool. Project your body into these construction planes. Now you have those perspective 2D sketches. These can be exported to dxf/dwg format. I hope it helps 
It works for me! Thanks
