Has anyone found a solution to this problem. We're only just starting to look at using Impression for our rendering however have hit the same snag importing drawings. The program is not much use if you can't import drawings. We've been using Corel Draw for year to render drawings (vector based program) but thought Autodesk could have a better solution. Seems a shame that they look as thought they are not supporting this product properly or helping develop it further to reach it's full potential. It has the potential to be a powerful tool.
