I cannot simulate tracker's 3D scenes built with AutoCAD and plugings like PVCase or VirtuoSolar. With fix structure I was able to solve it by changing the tolerance in the "shading scene construction > tools > orientation management". Most of the scenes I am building are placed in sites where irregular terrain characteristics having NS tilted trackers with tilt angles from -8Dgr to 8Dgr is very common. In my projects computing 3Dscenes under this scenarios is a must specially because I need to use bifacial modules.

	How can I process this type of 3D scenes ? What I am doing wrong ?
