The auto height option sets the extruded height for
a specific polygon based on its description or ID.

If the polygon's ID is in either name_XXX_mm or name_XXXmm
format, then XXX is translated into height in millimeters.
Use . or _ as separator for a decimal number.
Note that all whitespace or comma are saved as '_' in ID.

If the polygon's description contains line like
height: XXX mm
where XXX is any decimal number (use . as separator),
then the height is set to XXX millimeters.
Note that the description has preference over ID.

Otherwise, the height parameter is used.

This extension converts Inkscape paths to
extruded polygons in OpenSCAD.  Before
using, first convert objects to paths
with the "Path &gt; Object to Path"
menu item.

Note that the paths must be polygonal.
Non-polygonal paths will not render well
in OpenSCAD.  Thus, while you can convert
text to a path, letters with closed loops
will not appear as you expect in OpenSCAD
(e.g., the letter "o").

Inkscape's units of pixels are converted
to millimeters using the SVG Standard's
definition of 90 pixels = 1 inch -- since
inkscape 0.92: 96 pixels = 1 inch.
