How To Place Cantilever Supports Using Stretch Mode

The following example was created in the Support Model.dgn file, which is included with the sample BESM_Imperial project.

From the Support Frames toolbox, select the Braced Cantilever icon.
Double click the pipe segment to be supported.
When prompted to select a steel component, right-click to reject this option.
When the Properties Dialog displays, click in the Frame Type field and select one of the options from the grid.
Note: For this example, we selected type 1C, a flush mount with a 4-bolt plate.
Make sure in the Options section, the Placement Mode is set to Stretch.
Set a value for the Extension (Ext) Length. This is the length the cantilever beam will extend past the pipe it is supporting.
Click OK.
Use the mouse to move the cantilever image to the correct location along the pipe segment and left-click to accept.
Note: You can also use the Path Placement dialog to enter a distance if desired.
Next, stretch the cantilever from the centerline of the pipe to the snap point on the structure it will be attached to. In this case, the cantilever will be attached to a supporting wall as shown below:
Left-click to accept the placement location and complete the placement.
