# Deck Slab Elevation CADD and Tables \[SIG]

A deck slab elevation CAD drawing is a technical illustration that depicts the elevation (height) of the bridge deck at various points along its length.\
The Deck Slab Elevation Tables provide corresponding numerical data—such as station numbers, elevation values, and other relevant measurements—in a structured tabular format aligned with the CAD drawings.

## General

**Refinement:** The refinement parameter is used to discretize the bridge along its longitudinal direction. If the curve appears unsmooth in the CAD drawing, increasing this value may enhance its smoothness. Similarly, in the deck slab elevation table, elevation values are reported at the number of stations corresponding to the refinement parameter.

**Enable Default Locations? \[YES/NO]:** This parameter is used to enable or disable the default locations for the CAD drawing and the table. These default locations correspond to the Deck Left Edge, Deck Midpoint, and Deck Right Edge positions.

**Deck List:** This parameter allows the selection of decks for which the Deck Slab Elevation CAD drawing will be created or the Deck Slab Elevation table will be generated.
