Hi, About 10 years I am solved this problem, but looks must use any other tool in this problem. Or... anyone can help? When make laser-cutted part, need 2D. It is, I make product "sandwich" and all parts are really 2D. But, reason of easy desing, must make 3D. So, I make geometry. Then subcontractor take stainless steel plate. Or, plastic. Or. Or. And cut this geometry. Sometimes subcontrator use low-energy-laser-cutter, "120 watt" and cut plastic. He open my dwg in Corel or any other vector graphig program. Problem is, dwg/dxf is 3D. "Burst". "Layoutmode, export". Make all what you want, effect is same. Open it dwg/dxf in vector graphic program: You can see, there is many lines: You can see one line, but when you start cutting, it laser cutter make several lines... SO: IT IS NO ANY WAY EXPORT PURE FLATTEN 2D DWG/DXF!!!! How I solve this problem today? Layer "partxyz_2D", and Layer "partxyz_3D". First I make this 2D, then copy it to 3D. With this 3D I can build product, test, make modeling etc etc. But, simultaneouslly, manually I update this "2D" reason I can cut it. Is this truth? In Kc there is no any way export PURE flat 2D? Notify: LAYOUT MODE DXF/DWG EXPORT IS REALLY NOT FLATTEN. It is "bursted". So, still, again, from years to years: How I can export pure, clear, as hand-draw-2D????
