Scheduling Duct and Pipe Elbows by Angle

A common request we are seeing is the desire to schedule duct and pipe elbows by angle so that they can be scheduled and ordered. As the Angle parameter is a System Family it cannot be scheduled normally.

The help automate this process we have found that creating a Shared Parameter with a formula should pull the angle of the elbow, which in turn can be scheduled.

The process for goes like this:

1. Create a Shared Parameter file.
2. Edit the elbow families and add the Shared Parameter.
3. In the Family Types, set the formula for the Elbow Angle parameter to = Angle.
4. In the project, create a duct or pipe fitting schedule with the Elbow Angle Parameter (along with any other parameters). 

 

You should now have a schedule that shows the Angles. From here, you can filter the information to best suit your needs.

One thing to keep in mind, is that initially the schedule will show all fittings (Tees, Crosses, Transitions, etc.), so filtering by "Elbow Angle > Parameter Exists", should only show the elbow families with the shared parameter.

Here is a video of the process:
