    3D AutoCAD pline into a sweep - can it be done?

    Looking to do what appear to be simple, as very hard to do in Revit. How can I import a 3D Polyline as a DWG from AutoCAD, and use it as a Sweep in Revit?
    I am bothered that I am constrained to sweep to a path that is on one plane – man this bites.
    This also need to happen in a family that I can publish.

    PS - I think it is funny that this forums dictionary sees Revit as a misspelled word....

    You can accomplish this in the Conceptual Massing environment, using reference points, spline thru points, and adding profiles along the spline path to create the sweep. Dictionaries generally do not know "brand names"--type in "Levi's" or "Kleenex" or "Coca Cola".......LOL

      Hey Cliff..... I AGREE! =)

      Sweeps and Splines can go in all sorts of planes, and can even be curved in more than one plane at a time.

          Cliff - can you publish Conceptual Massing environments as insert-able families - say on Seek?

          Aaron - how did you do it? If you could tell me how to do that compound curve wave on the front - that would be helpful...

            Well now the plot thickens, doesnt it? What exactly are you trying to model, and for what purpose?

            If its a piece of equipment, or something similar (Toilet, sink, light fixture, equipment rack, office equipment, etc), i wouldnt model it in the CME at all. Even without the CME, Sweeps in the Family editor CAN have paths that are on more than one plane. There is Pick Path, and then there is Pick Line which is WITHIN Sketch path. The latter is single plane only. The Former can turn in 3D along complex paths.

            I'll tell you this though:

            If youre making content for Seek, and there is Imported CAD "anything" inside it, smart Revit users will add you to a list of content builders to never download content from. As for publishing, i have no idea. I have Seek blocked through IT here.

              Yes--they are just .rfa files, so they should upload to content sites--however, file size may be a limitation of the website.

                I have no intention to import from CAD - native Revit all the way - yahooo!!!!
                Family category is furniture. I would like to keep my specific product not the focus, but the struggle I am having modeling a path the sweeping a simple circle along that 3d path. I attached 4 JPG’s. Do you think Sweep-Wish-4 is possible? Or even simple? Handle is not important, just the wire.
                Please excuse my ignorance, what is CME?
                I do appreciate you help, this forum has been extremely helpful and motivating to push my skills further.
                Thank you and look forward to you reply,
                Ken

                  CME = Conceptual Massing Environment. It is intended for creation of overall building form ( think organic buildings by Frank Ghery, Zaha Hadid, etc. )

                  For your small-scale objects, use the Family editor, and use sweeps, blends, extrusions, etc.

                    You can still use Pick Path for a sweep, which is NOT the same as going *sketch path* and then using *pick lines*.

                    Pick Path will let you pick 3D lines. So make model lines in 3D that follow the 3D path you want.
