The units are clear: Inkscape uses 90 dpi when saving an SVG file. So, in that way it’s a simple conversion to mm or any other absolute length. 25.4mm in the Inkscape GUI is a distance of “90” in the SVG file. The confusion here is why Inkscape does not fix the coordinate system offsets that it writ...

I feel like I must be missing some settings, because the results aren't intuitive. At a high level, I am writing a script to convert an Inkscape file with graphics into a list of drill locations to send to a metal fabricator. So, I parse the XML data from the Inkscape SVG and massage the numbers int...

Thank you for the tips and the detailed explanation! Xav's solution ended up being a big improvement. I had never seen "guides" before. Giving a guide coordinates that are identical to component center coordinates on the circuit board makes something that I can snap the center of a graphic...

I do front panel graphics for electronics using Inkscape, and one part is quite painful. A circuit board, not the graphics, determines where knobs and components go. I then need Inkscape to center graphics to line up with the drill holes in a circuit board. Here is an example... First I make a circu...
