Change Bends (Siphonic Drainage)

Shows step-by-step how to use the Change bends command to change a 90° bend for two 45° bends, or vice versa.

Before you begin

You want to change a 90° bend for two 45° bends, or vice versa.

Navigate to:

Project tab ➤ Discipline Roof Drainage ➤ 3D - Floor Planning ➤ Create tab ➤ Command group Symbols / Components ➤ Symbols ...

Initial situation:

Change bends Floor planning Linear Solutions AutoCAD

Procedure

Click on the Change bends button .
Use the window technique to select the point in the pipe network where the bends are to be changed.
A context menu with the variants for the bend connection opens.
In the context menu, select the option that should replace the bend.

Results

The bend is then changed.
