Depends if you're interested in the Revit systems aspect, but to model that you could use an in-place sweep family to create the top elbow (setting the category to duct fittings and adding a connector to the end) and another in-place family for the straight fitting with a normal transition duct fitting at the end of it. (See Revit screenshot)
How would you draw this? What fittings do you use?
I start with big purple R --> new -> family and categorize it as a duct fitting (multi-port). Then I model it. I never use in-place families.
Ahh..So thats how you do it. I was going crazy looking for duct fittings. Thank you guys!
Cwclose. if the file is not too big. can you please attached that model so that I can study it.
The file is too big for the Autodesk discussion groups. I can send you the file via email or ftp. That said, I agree with Sandleaz, if you can use a regular duct fitting family vs. in-place--do so. However, if you're only needing the geometry (as is the objective of many MEP design and construction firms) and you aren't using the air flow data then modeling in-place might be quicker for unique circumstaces.
