Torsional constant for DXF shapes

[jessebluestein]

FIrst of all, thanks for creating this awesome package! It's super impressive. I am trying to use it to analyze a complex shape that I'm importing from a DXF file. It looks like it's running successfully and I am able to print out the section properties just fine. However, the torsional properties are not listed. When I call the get_j() method, it returns None for j. Is this a limitation of sections imported from DXF geometry?

Figured it out! Just needed to call sec.calculate_warping_properties()

Now it's working - thanks!
