I have some oval duct in my model and the fitting seem to work except for perhaps the most important one... the mitered oval elbow. When I model a simple duct run it works fine, but when I try to go vertical (drop or rise) I get the following message...


"The routing solution failed because there is no default fitting type specified or the fitting cannot be found in the project. Ensure the fitting is loaded in the project and try again."

My not-so-efficient work around is to model in the horizontal and then rotate the fitting accordingly.

Any suggestions would be greatly appreciated!

Thanks!
