Whenever I finish a design, I go through and copy and paste the faces of each part into a separate area, select them all and use an extension to export them as a dxf. Everything in my model is cut out of plywood on a 3-axis CNC router, so I’m only interested in the 2d faces of the individual components.
Is there a method using SketchUp that would be less sloppy? Like, if I go back and change my original design I have to copy and paste the 2d faces again, which adds time and increases the chances I’ll make some stupid mistake. Is there some way that I can set these up so they dynamically update if I modify the original parts?
Turns out the .dxf export extension I was using didn’t really work all that well with 3d parts, but I found out I can do a top down parallel projection view then export a 2d image as .dxf. This gives me exactly what I need for my CAM software.
Another question: is there a quick way to set all selected parts to the same Z level? Copying and pasting, then doing rotations, then manually moving each part along the Z axis can take some time with a complex model. Anything that can save me some time would be awesome!
