The trunnions in the Supports application are template driven. A default set of trunnion templates are supplied with the Supports application.

A trunnion support can be created on the following types of piping component:

• Elbow

• Bend

  A plate is cut from an elbow of the same size and is itemised as extra material on the isometric drawing.

You can create trunnions with a number of associated ancillaries, you are guided by a series of prompts throughout the creation process.

A trunnion is designed to a standard. A trunnion can have associated ancillaries, which are themselves standards.
