Rounded object looks choppy in the svg

So two things to play with:

https://github.com/IfcOpenShell/IfcOpenShell/blob/v0.7.0/src/ifcopenshell-python/ifcopenshell/draw.py#L121 and more importantly setUseHlrPoly(False).

By default we use Polygonal HLR because anyway both svgfill nor shapely can deal with curved SVG elements (I guess...).

The other thing to try is:

s = ifcopenshell.geom.settings()
s.set_deflection_tolerance(0.0001)

Thanks @aothms

Reporting back.

When using setUseHlrPoly(False) the following is svg is output. Neither 'Calculate Shapely Surfaces' or 'Calculate SVGFills Surfaces' is enabled.

...

Dumb question, where do I add the following?

s = ifcopenshell.geom.settings()
s.set_deflection_tolerance(0.0001)
