Place Approach Slab
To place an Approach Slab at the start or end of a bridge use the following procedure.
You must use an existing deck template. Your model must have Approach Reference Lines defined before placing an Approach Slab.
- On the Home ribbon tab, select the Place Approach Slab tool in the Approach Slab group.
- Location, select either start or end of bridge.
- (Optional) Sync with Deck, uses the same template as deck and aligns all offsets.
- In the Place Approach Slab tool settings dialog, select the template to use.
- (Optional) Specify additional settings such as Start or End Station Offsets.
- (Optional) Horizontal Offset, transverse offset if any.
- (Optional) Vertical Offset Deck, input offset at the deck end of the approach slab.
- (Optional) Vertical Offset Sleeper Slab, input offset at the free or sleeper slab end of the approach slab.
- (Optional) Clear the Add Constraints check box if no additional placement constraints are required.
- (Optional) Sleeper Slab, check this box if a sleeper slab placement dialog should be shown following the data point.
- In the view window, data
point to accept, and see the approach slab solid placed.
If you checked the Add Constraints option, then the Solid Constraints Definition dialog opens.
- (Optional) Specify any necessary point or variable constraints along the deck and then click Apply.
- If variable constraints are being specified, the template tab shows the effect of the variations defined at user defined distance (use the slider or enter cross section distance).
While a 3D Approach Slab object is placed following the vertical profile elevation, a 2D deck layout (decoration) is placed at elevation 0 in the model. This 2D layout is updated whenever the Approach Slab object is changed, and the line work has the necessary features associated to place it on a separate Level.
