Inserting Trimmed Elbows
You can insert trimmed elbows after converting elbows to the required trimmed elbows.
Using the Insert Fitting functionality in Spec-driven Piping mode, you can:
Specify a selection name during fitting insertion and insert a trimmed elbow at the specified vertex location.
Insert a trimmed elbow based on the automatically determined selection name of the nearest standard elbow fitting (for example, an elbow fitting with an angle closest to the vertex angle).
Insert trimmed elbows at all vertices of a pipeline by automatically determining the appropriate elbow fitting selection names based on the vertex angle of the various vertices.
To Convert Elbows to Trimmed Elbows
You must convert elbows to trimmed elbows before you can insert trimmed elbows.
1. Copy the original elbow part to <original elbow part name>_TRIM.PRT.
2. Change the angle dimension symbol from ANGLE to TRIMMED_ANGLE.
3. For each instance in the generic, that is, for each size, create instances of different angles. For example, you can create instances using an incremental value of 1.
 
* Nested instances must not be used.
4. Ensure that the ports align properly with the inlet and outlet of the elbow in the trimmed instances so that the fittings can be inserted.
