Rhino + enscape + vray

Hello,

I exported a dxf from QGIS with buildings and topography, i saved as a dwg in autocad, then I imported this file .dwg file in Rhino and used a script in grasshopper to extrude the buildings and another one to do the topography. The problem is when I try to render this elements with Enscape or V-ray there is a bug in the objects and everything looks like the photo. (there is not a superpostion of surfaces)

I think there is problem with the file that came from QGIS, because when I draw something in another autocad file everything works. But with this file that came from Qgis there is always this bug. Does somebody know the solution please???

Hello,

It’s likely that your model is too far from the origin. Move the center of your geometry to 0,0,0 and this should solve your problem
