I’ve been learning Inkscape by tracing a bathymetric map of Lake Murray in South Carolina, so I was ready when I got my Glowforge on Thursday. The top couple layers are Proofgrade Medium Maple Plywood, and the rest are Home Depot 1/4 inch plywood, b/c they are supposed to represent a bigger drop in depth (nothing to do with it being dirt cheap…)
I’m working on similar layered designs, and to keep track of the “floating” pieces I figured out I would just score numbers or letters on to them (except for the top layer) and, if needed for really complicated designs where accuracy matters, cut additional locating holes in those lower layers, that will just fit a toothpick.
That looks beautiful!
I ran into some trouble painting on my birch ply (also non proofgrade), did you have to seal your’s first? Or did you spray paint them? Are all the blue the same color and looks darker cuz of the layering?
No idea on why the svg isn’t showing, but would you mind sharing where you obtained the original map? No shortage of topo data but bathymetric seems hard to find…
Your upload shows as an SVG – I was able to download it and open it in Inkscape. The document setup was clipping the preview in Discourse (the forum), so here’s a version on a 20x12 artboard:
Fun story, I couldn’t find a decent bathymetric Lake Murray anywhere online, but I did stumble on this picture of someone else’s laser etched version. I wish I could give them credit, but I can’t seem to find it again on google.
