I am just getting back into flatbed CNC after a long hiatus. I wanted to brush up on, and catch up on, the latest techniques in using SketchUp (CAD) and VCarve/Aspire (CAM). I notice all the cool people on Youtube, at least the ones that haven’t moved to Fusion360, are making a clone of their SketchUp projects in a flattened state, or explode the components, or a variety of other tricks rather than the more traditional components with faces & edges on layers.
What is the reasoning behind this? I looked at a number of videos and tutorials and they are all doing this so I am wondering; is this the more efficient way of doing the SketchUp CAD to VCarve CAM these days? I tried it, and found it slower and far more fiddly, so I am probably missing something fundamental, a key trick that is assumed by all the tutorials that I don’t have in my workflow.
