I’m quite a Sketchup novice and would appreciate guidance from the more experienced users here. I am attempting to model scratches on the surface of a metal object, in this case a chisel, for use as a demonstration of a sharp edge. I suspect that this can be done using either the push/pull or the follow me tools. The scratches would in real life be very shallow but still visible to the human eye. Ideally, I would like to be able to magnify or minimize them by zooming in and out, to illustrate the effects of magnification during the sharpening process.
I have downloaded from the 3D warehouse a model of a chisel, so I do not need to create that model from scratch. I just need to place small scratches (as would be left by abrasives) into the surface.
Thanks for any and all help!
