To place a bridge deck between supportlines, use the following procedure.

1. Either:

   For…	Use the following tool…
   typical slabs	On the Home ribbon tab, select the Place Deck tool in the Superstructure group or key in bmgeom deck placebetweenpierlines
   cast-in-place box bridges	On the Home ribbon tab, select the Place Advanced Deck tool in the Superstructure group or key in bmgeom deck placeadvanceddeck

2. In the Place Deck tool settings dialog, select the deck template to use:
   1. Click […] adjacent to the Template Name setting. The Template Selection dialog opens.
   2. In the Decks list, select template to use.
   3. Click OK.
3. (Optional) Specify additional settings such as offsets and orientation.
4. (Optional) Specify deck breakback offset distances for the left and right sides at start and end of deck. The breakback distance is measured normal to the edge of slab. Deck breakbacks are squared ends at skewed supports.
5. (Optional) In the Place Deck tool settings dialog, clear the Add Constraints check box if no additional placement constraints are required.
6. In the view window, do the following:
   1. Data point (i.e., click) a supportline as the first deck boundary
   2. Data point a different supportline as the second deck boundary
   3. Data point a third time to accept
   If you checked the Add Constraints option, then the Solid Constraints Definition dialog opens.
7. (Optional) Specify any necessary point or variable constraints along the deck and then click Apply.
8. 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).
