Hi everyone,

First let me say that I love Gismo, it has completely changed my design workflow. That said, I have encountered an new error when attempting to run OSM3D:

Runtime error (TypeErrorException): unsupported operand type(s) for +: 'NoneType' and 'float'

Traceback:
line 1854, in liftingOSMshapes_from_groundTerrain, "<string>"
line 637, in createThreeDeeShapes, "<string>"
line 805, in script

All the 2D OSM shapes and 3D terrain load just fine, but it breaks when attempting to run OSM3D. If any of you have any ideas of a fix, I'd really appreciate it. I'm not exactly sure what is going wrong.

The same script runs just fine at a different set of coordinates. The site I am trying to construct is in urban Copenhagen, maybe something about OSM's data there is the problem. Thanks for any help that anyone can provide!
