hard to measure slopes and curves |
Anyone reading a CNC blog will be familiar with creating a drawing in CAD but what if the aim is to reproduce an item that's difficult to define with a few caliper measurements ? The picture on the left is part of a toy truck.
It's possible to trace the photo itself in software. It's also possible place a 3D object on a flat bed scanner. In this example a quick trace was was done with fine tip marker. The trace was placed on the scanner and the resulting b+w image opened in Inkscape

The dxf can be imported into CAM software to create the gcode file. Fusion 360 was used for CAM. As mentioned earlier the digital camera image can be imported directly into Fusion for tracing, I am simply more comfortable with the Inkscape tracing features. The picture below is a test cut done in a piece of scrap.
