This is kind of a hint/tip, but I can’t post there, so I’m putting it here.
I kept noticing that the sizes of things I drew in Inkscape would change over time, just by a few hundredths of an inch, usually, but it bothered me because I couldn’t figure out why it was happening. I finally figured it out.
Turns out that Inkscape apparently takes stroke width into account when calculating object sizes. If I draw a 1.5" square at stroke width 0.002", then change the stroke width to 0.01", the measurements of the square change to 1.510" in the top bar.
I guess this makes sense, in a way, but also in a way it doesn’t. Which is usually a good indication that I need more coffee…
I haven’t fully comprehended the ramifications yet, other than that since GlowForge ignores stroke width, it’s going to screw with drawing accuracy.
Maybe there’s a way to leverage it when working with kerfs…I can’t decide for sure.
Time for coffee.
