Aux Alignment option is used when defining custom beam paths. You need to have civil alignments representing the beam paths.
You must have at least two supportlines.
A beam layout is used to specify the general girder geometry for a slab and girder bridge. This procedure is used for concrete and steel girder bridges.
Procedure:
-
On the Home ribbon tab, select the Beam Layout tool in the Superstructure group:
or
Key in BMGEOM BEAM PLACECORRIDOR
- (Optional) Type a Name for the beam layout in the Place Beam Layout tool settings dialog.
- To specify the layout limits, do the following in the view window:
- data point on the first supportline to use as the start limit line
- data point on the second supportline to use as the end limit line
- data point a third time to accept
The Beam Layout dialog opens. - Select the Placement Method: Simple or Continuous.
- Select the spans to which the current layout will apply
- Click on Add and select the first civil alignment that represents the first girder.
- repeat the process to add aux alignments for other girders:
- Set the number of beams according to the layout.
- Set the Spacing for all beams to zero as we are using Aux Alignment
- Change the Spacing Reference to Aux Alignment and select corresponding civil alignment
- Validate the layout and click on Save.
