i need support for Autodesk revit help me please
There is a public Revit newsgroup (alt.cad.revit), but AFAIK it is only hosted on Revit's own servers. If you go to www.revit.com, there should be a link somewhere to their server where you can find this group. OTOH, I may be wrong, as this was all correct before Autodesk bought Revit, so may have changed now. Matthew
