I asked NeTraverse Support about IntelliCAD/AutoCAD. This is the answer I got: " We have a number of customers running AutoCAD under Win4Lin. We have not had any reports either way regarding IntelliCAD, but so long as it does not require anything Win4Lin does not support (DirectX, etc), then I expect it would work as well as AutoCAD does. Win4Lin currently only supports Windows 95, 98 and ME. " I do not know what really is the direct-x and do I need it? (I haven't studied that M$-language) But I know that I need to work with 3D. -maRia
