Vectrosity line thickness different with cam zoom.

1. When I'm zooming my camera, 3d line thickness is different, but the lineWidth value is same. I use Draw3DAuto. But I dont need dependence from camera distance. And I cant use Draw3D, because camera at this moment in different place in far from line.

2. And there is second issue: Vectrosity takes into consideration camera distance, but not parent distance.

Im little disappointed of Vectrosity, because I bought it for realise my goals, and now I dont know what to do. Is there any way to fix that? P.S. in Vectrosity there is no Validation/Invalidation, its so poor for me :(
