Is there another easier way to do it ?

I design this box with Autodesk Inventor, then export all the parts to dwg format.

Open the parts of dwg format using AutoCAD, save as them as dxf format of R12 vision.

Then import them with Inkscape, save all the parts as pdf format.

Then laser each parts and assemble them.

ohhhh, so diffcult step what I had done.
