Sweep along complex 3d edge

[spm8C88E]

Hello, I'm trying to create a sweep along a 3d polyline from ACAD. Here's what I've tried:

Link the DWG and create an in place sweep. try to select the linked DWG as the 3D edge but am not allowed.

Insert the DWG into a family and explode the file. When i do this the lines are no longer 3D so that doesn't work.

Insert the DWG into a conceptual mass file and try to draw points on the line but cannot snap to the DWG. 

I tried even doing to the sweep in autocad but it does not work with my profile. If i break the curve and make multiple sweeps it looks like I can do that with a circle but not my profile.

Opened the DWG in Rhino and tried to sweep along it. This sort of works but has all kinds of messy edges. I was hoping i could use rhino.inside or some how use use this model to select 3D edges when making an in-place sweep but it's proving to be messy and hard to make a continuous sweep....

Anyone have any tricks to do this type of thing in Revit before I go back to Rhino. DWG with line and profile attached. 

thanks!

Are you asking how to make those dwg lines used in revit to pick edges for the sweeps path? or what exactly?

I'm looking for a way to create a void with the profile swept along that path (both in the dwg file). It would be ideal to make it in revit either to use the dwg path or convert the dwg lines to something usable in revit. So far I can't find a way so I'm open to other suggestions, such as creating it in rhino and importing using rhino.inside. Possibly even a sweep in civil3d. Rhino is the most promising but seems like a lot of work to make a decent sweep.

Some background: This path is the path of an underground utility. There is a certain exclusion zone around this utility that cannot be touched. I would like to show this relationship with reasonable accuracy in section to detail the landscape around it. Any suggestions are welcome 🙂

Revit does not support polylines so you would need convert that to something which Revit can use. For instance, you can use Dynamo to get the curves and to generate model lines which you can use as a path for the sweep

You can also do it in Rhino then syn that into Revit as a solid rather than a void. You can cut using solids by jusing Join Geometry then hiding the solids (either by element or by filter ...)
