**Elevation view with levels **
### ICDAS REVIT BRIDGE create also automatically levels at all hangers at the arch in all elevation views. It can be### used to compare with Z-Coordinate in Lusas model directly. Note that in Revit Annotate tab, Dimension panel,### one can use Spot Elevation, Spot Coordinate and Spot Slope to document elevations, coordinates and slopes at### any point/line on the bridge.

**The arch of line-segment and the beams intersection at steel frame deck** The ellipse arch is created by multi straight line-segments at the points where the hangers are attached (clickto enlarge the figure below). At the steel frame deck there are spaces at intersection of the longitudinal, transverse and the diagonal beams. It is reserved to Revit structural connections.

### Input He control shape of the arch & free height above the deck The 4th point of the arch is reduced in height by 321mm and 103mm when He increase to 200m and 300m from 100m, respectively, 19373-19052; 19052-18949; The 1st point above the deck is reduced in height by 334 and 95mm, similarly, 5351-5017 and 5017-4922 The 1st case the height of the 1st point above the beam deck point is 5351-1598=3753m. To obtain a free height 4630, the deck need to move 4630-3753+250+300=1427mm down. If not possible, then raise the Hs% (the case the longitudinal profile of the road is fixed)
