inkscape-openscad-poly's Issues

Curves rendering coarsely when exporting

Great plugin, thank you!

How do we control the number of surfaces when saving as .scad? Here's an example of source and resulting rendering in openscad:

Limiting significant digits

Per Schmarty, "I pushed an update a couple of days ago to have it keep 5 significant digits. Due to how floats are stored, this can sometimes produce weird long numbers due to small float errors."

For most printing purposes 1 significant digit, and at a maximum 2, would be more than adequate. This would mean precision down to 0.01mm, which is about as fine a feature as anyone would need from an Inkscape->OpenSCAD polygon tool. The current setup (as of 2011/10/23) is creating very long significant digit pairs for XY coordinates. Example, "[-11.556710000000001, -0.96667000000000003]". For my purposes, "[-11.6,-1.0]" would be sufficient.

Out-dated installation folder for Mac OS in README.md

Hi Marty,

First of all, thank you for this plug-in, it is fantastic!

Just wanted to let you know that Inkscape installs differently on High Sierra and Mojave.
Official Instructions here

The folder we should copy the src/* is: /opt/local/share/inkscape/extensions

Thanks,

George

Changes for Inkscape 1.0?

Got an email about possible updates to make:

Thank you for providing this extension for Inkscape users!

This is just to let you know that most 3rd party Inkscape extensions,
like the one you made, probably will not work with the upcoming new
Inkscape version, the long-awaited version 1.0.

Here is the info you need to update this extension, so that it will work
with 1.0 and future versions.
https://wiki.inkscape.org/wiki/index.php?title=Updating_your_Extension_for_1.0

If you have further questions, you can contact Inkscape developers via
mailing lists (https://lists.inkscape.org/postorius/lists/?all-lists),
forum (https://inkscape.org/forums/extensions/), or the chatroom
(https://chat.inkscape.org/channel/team_devel)

If you have already updated it, please disregard this message.

Extension does not show up in Inkscape 1.2 for Windows

Running Inkscape 1.2.2 on Windows 10.

Copied the contents of the /src folder to C:\Program Files\Inkscape\share\extensions
Opened a .png file, Shift-Alt-B to "Trace Bitmap". Preview contains what I want. Apply.
Select the object, then go to "Path" menu and choose "Object To Path".
Go to "File" and select "Save a Copy". There is no file type for "OpenSCAD polygons" in the filetype menu. (see attached screenshot),

Got the same results after copying the contents of the /src folder to C:\Users[MyUserName]\AppData\Roaming\inkscape\extensions

support python3

I use this extension for openSCAD to export .scad file.

But it did not work in python 3 env. So I modify some code to let it works now.

Parameters

First off, I really appreciate all of the work that you have put into this. If you could do a little more, it would be greatly appreciated. I see that the output has smoothness hardcoded and the relevant(?) line says subdivide_cubic_path(sp, 0.2) # TODO: smoothness preference. Can you please add that (and anything else helpful) to the interface?
