Is there a simple way to Trace/Scan a gasket into CAD
There are softwares like Inkscape will trace a high contrast edge as a vector and then you can export them as .dwg usually. This will work with most of the CAD softwares or directly to laser/water cutters. You need to know atleast a hole dimension to be able to scale the picture. The longer the reference dimension, the smaller the error will be in the end result.
