Other units than px, % or none (such as mm) should be handled about inkscape-openscad-poly

[martymcguire]

This is an issue that crops up when using this (aging) plugin with recent versions of Inkscape when a document has no units. Try setting the units to px or mm in document settings.

When I set from mm to px, it finally produced a nice SCAD file! When I looked at the source the getLength() supports only 'px', '%' or '' (no units). Nice thing is that I can just modify the python script and it has an immediate effect, no need for building anything. :)

Thanks for help, Marty!

Maybe I could try to fix some other bugs:

• the SCAD file contains some invalid lines at the beginning:

('UNITS:', 1541.312, 'px')
('UNITS:', 1203.1851, 'px')

• when there's a more complex shape, multiple modules are created, instead of a single group
• it should handle other units (such as mm) without a crash

I like more this approach of directly exporting to SCAD rather than to intermediate DXF. Then there's no need to import anything, just include an SCAD file.

Hmm. Not sure where the spurious lines in the OpenSCAD are coming from. Maybe some bad handling of (new?) metadata in the Inkscape SVG file?

Unfortunately, I haven't had time to play with this code in a long time. Any improvements are most welcome!!

See my pull request #5.
And please test it. I only tested it myself so far...
