Could you please provide guidance on how to import an SVG file into
openSCAD and represent it as a list of points?
Thank you,

Using base OpenSCAD, you can't. You can import an SVG file as a
polygon, but you cannot extract the list of points.
However, it happens that I just saw something using the Pathbuilder
library that consumes SVG path text and returns points. See
https://openscad.org/libraries.html#pathbuilder .
The documentation says that it accepts the full SVG syntax, but I think
that's a little misleading. It looks like it accepts the SVG path
syntax. That's important for two reasons: (1) SVG per se is an
XML-based format of which paths are only one part, and (2) not all SVG
shapes are represented as paths. I just created a test file and
happened to draw an ellipse; it's represented in the SVG with the
<ellipse> element, not as a path.
Anyhow, if you convert everything into paths then you might be able to
copy-and-paste the path strings out of the SVG and into OpenSCAD source,
and use Pathbuilder to process them.
You can use search and replace in a text editor to convert an SVG file
to an OpenSCAD polygon format. Then, if you want to do it a number of
times, then get ChatGPT to write a python script to do the same.

Hi Jordan and Raymond,
Thanks for your insights. It sounds like the method I've been using is
indeed the way to go:
- Create a drawing in Aspire.
- Export it as an SVG.
- Use UltraEdit to extract only the path information.
- Copy and paste the path data into OpenSCAD as a string variable.
- Utilize Pathbuilder's
svgPoints()function to create the list of
points. - Finally, use BOSL2's
deduplicate()function to ensure a clean list.
Thanks again for confirming this approach.
Best,
Joe

There are a few Inkscape plugins that automate much of this - basically
letting you copy/paste from Inkscape into Openscad point lists. I don't
remember much of the details, and I have my own plugin that also copies
curve date in various formats to the clipboard, so I sometimes mix and
match depending on what exactly I'm doing. But it's worth looking into
existing plugins, manually copying and fixing up gets old fast.
Cheers

I don't do these things, but it sure feels as if this comes up
repeatedly. Maybe a Wiki page or similar?
