dwg file transfer

[matt_vinoir]

dwg file transfer problems from vectorworks.

when i import into viz 4 the planes of a wall for example appear to have interpollation issues.

This is only noticable when radioisty is on and i think only with daylight lighting. ( as its an external shot i need daylight system sods law!)

Also the gi solution shows up black in the viewport eventhough when i renderthere is reasonable light levels. Im confused. I can model in archicad and export the 3ds if that is better but i like modelling in vectorworks
