Whenever I create a 3d-solid model in autocad (2007), export it to 3ds and import it in Ecotect v560, the import goes alright but I get shading "anomalies". I don't understand why those "anomalies" occur.
I've attached an example. I've noticed this strange behaviour with several different 3d-autocad-models. In some models it's a lot worse compared to the attached example. Even to the point of being unusable.
I've tried converting the solidmodel to faces and import it through a dxf-file to no avail. I tried different Autocad-versions, tried a real 3ds-model, etc. One of my collegues confirmed this behaviour and told me that it doesn't occur when the model is made in Ecotect itself.
I have used te model on a pc with an good graphic-card (GF 8600M GT with 256 mb).
Anybody else noticed this too? I would like to know if I can do anything to prevent these "anomalies".
