Is there a way to read an SVG file or to convert an SVG path to generate a usable points array?

No but there is an OpenSCAD exporter plugin for InkScape so you can read an SVG and export an OpenSCAD file that has a point list in it. Also there is a Python library that will read SVGs and it would be easy to write a script that outputs a point list in OpenSCAD format if you know Python.

If you're an Inkscape user and and if the starting shape is a single loop and if it's a one-time exercise (so a manual process isn't too much of a burden) : If your starting shape in Inkscape has bezier curves, use 'Flatten Beziers' to convert the shape to have only straight segments. Open the XML editor, and select the desired path. Make sure 'Show Attributes' is turned on. Copy the d attribute and paste to something like MS Word. You'll have a leading and trailing control symbol, such M and Z, which should be deleted. That should leave a list of point coordinates with a space between each point and a comma between the x and y values. Then use Replace All to adjust the layout as required. The method is a bit of a kludge, but it has worked for me a few times.

Thanks Steve This is actually the way I have been doing it except I use UltraEdit instead of MS Word for replacements within the Inkscape path. Also, when I do the Extensions -> Modify Path -> Flatten Beziers each point gets separated by the " L " (line to) svg command. By replacing these with "],[" it works great.

There is the pathbuilder library which says: function svgPoints(s) // // Processes a SVG path string and returns a 2D point list. Sounds like it does what the original poster wants? https://github.com/dinther/pathbuilder On Thu, Feb 2, 2023 at 1:18 PM Joe Weinpert <joe.weinpert@gmail.com> wrote: > Thanks Steve > > This is actually the way I have been doing it except I use UltraEdit > instead of MS Word for replacements within the Inkscape path. > > Also, when I do the Extensions -> Modify Path -> Flatten Beziers each > point gets separated by the " L " (line to) svg command.
