Need bigger pipes

[dave.redding]

Is there any way to get larger than 12" pipes to show up in the piping pull down? (I need 20").

The xml file shows up to 24"...but it does not show up elsewhere.

Any hep would be appreciated.

In the properties dialog for piping, change the material type to steel. This will allow you to select piping up to 24"

Hmmm. Now the piping seems to be of the "ultra-short radius elbow" variety.

Any thoughts?

What do you mean by "short radius"?

The the default elbows in revit have connection points right where the radius starts. Do you need an extension from the radius start? Like in the attached picture?
