[esp-r] Import of zone geometry from Blender

[Lars O. Grobe]

Hi,

as I got rather used to use Blender (v2.71 used) to create geometry for simulations, I wanted to investigate the possibility to use it with esp-r and tried to import some simple test object (a cube). However, regardless wether I export the surfaces as 3dfaces, polylines or polyfaces, esp-r crashes during the import. I have a fresh install based on yesterday's svn, built using gcc v4.9 on Mac OS X v10.9.5 (Darwin v13.4). The last messages I get:

--

Manually calling ecnv leads to PYDXF files containing no geometry:

Has anyone out there found a way to get geometry from Blender or any other open-source modeling tool into esp-r?

Cheers, Lars.
