Before the sketch master can export cad drawings, you need to set styles. In the edge style, you don't want to display any contour endpoints, just display the edges. Sketch master will export cad according to your current settings. Note that some components are hidden by edges, and these hidden lines will not be exported. Regarding deformation, ensure that the model is accurate and the viewing angle is positive. I've never encountered deformation. They are all vector software. Computers don't have brain cells that can deform, do they?
