Numerous ways. Search and ye shall find.

1. Consider IFC export to a Revit IFC Import.

2. Link CAD through Revit (slows Revit down a bit)

3. (My way) Save file as separate copy, explode CADduct objects, create generic model Revit Family, insert cad, load family. Be mindful of origin points in both files.

If you are just interested in being able to view the CADduct file without intelligence, you can save your working DWG file as a seperate name, go to your Main Database, Take-off TAB, CAD Settings & on the far right column within the "General" Area say "Yes" to "Save Graphics with DWG".......CAUTION: This setting will make the subject DWG 4x the original size BUT is better than utilizing IFCexport.

Final note: be sure to change the setting back to "No" after you have closed the renamed Subject DWG file so that the other projects are not affected.

I have been asked to do just this today...

IFC is OUT of the question... on this floor plan I am working on the file was a whooping 1.6 Gigs in size...

Other option to save graphics made the file size down to 15 MEGS, while still huge, is more manageable than 1.6 GIGs...

All solutions we have tried (all of the above) still render the Revit drawing crap when plotting. We still need to have a solution for getting native Revit objects into the .rvt files from CAD because drawing in Revit is still a LONG way off.
I know there are solutions but they cost $$$$$.

The solution is in Australia. Ask Jim Reis when it'll be in America.

I heard the same thing, that they are testing a BETA version of an Object Enabler for REVIT in Australia...

Just finished running (ruining? LOL) a test and the file size is still huge at around 75 Megs, the load into Revit took forever and all of our objects are made of lines so they do not shade.... looks horrible...

The objects need to be exploded and brought into a generic model family for 3D Faces to be created.

This is the method that I've used in the past, and it works well with less complicated geometry, or smaller files. The issue we've had is coordinating with CADduct users after the models grow in complexity. Once we're talking about linking in all the MEP on an entire building floor, all of these methods fail.

I'm on a pretty decent PC here. I7 clocked over 4ghz, 12gigs ram, nvidia 480gtx, etc....
Even on a healthy machine, the CADduct files, exported to .dwg become unusable when exploded.

Hey Santos, small internet huh?

I'm still up the creek getting the .dwg's into any format I can coordinate with. I've been in touch with TSI about the Aussie plugin, but that still seems to be a ways off.
