    I've never used Archicad, but you can link a cad drawing and trace over it, snapping to endpoints and intersections and such. Is that what you are referring to?

    You have to export the ArchiCAD views to DWG then import the DWG's into Revit from the Insert Tab, then Link CAD...

    And yes, Revit can do everything that ArchiCAD can do and more/less... The only feature I still like on ArchiCAD vs Revit is you can "Unlink" a detail or section view from the model. While this works great in the CD phase, if you unlink before CD's and the model changes its a pita to start over or re-update the link. Because of this unlink function and the explode to 2D capability I have never had a project stay in 3D through CD's. (The Architect's always over-rule me in that decision)

    Oh...and the walkthru feature in AC kicks Revit's butt too...if your a gamer you know exactly how to navigate the model....(WASD & mouse)

    In the ribbon, under the insert tab, there is a button to link a dwg file. Just click on the button, browse to the file, and select ok. It's now in your model.

    Can you link in a DWG and trace it? Yes. Should you? Nope!

    To add to Aarons responce. The reason why you shouldn't is because the unit conversion from other drawing formats can sometimes cause in accuracies with in Revit. IE the wall that in .dwg format is 30'-0" when drawn on top of in Revit will turn into 30'-0 7/256" NOT FUN!!!!

    One more notch for never using other programs. Revit = Better anyways

    Use the "pick line" tool when creating geometry from a linked cad file. Then clean up that geometry with other Revit tools.

    Okay, I have a question please if someone could answer I would appreciate. I have linked a cad file and I am using it similar to an X-Ref in Autocad. I work for a mechanical construction company and I use the engineer cad file to create my model by basically tracing the engineers design. Until recently I did this using Autocad MEP where I created a 3D model from the X-ref 2D cad file. Usually I would leave in notations, symbols, etc. and delete the remainder of the lines and text. To make a long story short, is there a way to edit the linked cad file inside of revit mep 2012? Or am I going to have to open the cad file in autocad mep, edit it there and reload the file in revit? Look forward to hearing a response and thanks in advance.

    Revit does not have a way to edit a linked DWG file inside of Revit. To make edits to the DWG file you will have to open it in AutoCAD (or AutoCAD MEP), make your edits and then reload the file in Revit.

    If you are just looing to make small modifications you could create Revit elements from the DWG underlay and then turn off the visibility of that layer/layers in the DWG in the visibility and graphics dialog.
