Bridge Box Girder 2

C3D BridgeBoxGirder2 — multi-cell box girder with two hollow cells

At a glance

KindSubassembly (composed into an assembly)
DomainBridge
Civil 3D equivalentBridgeBoxGirder2
Geometry37 points, 37 links, 3 shapes
Conditional geometry12 of the points are created inside a branch — which ones appear depends on the parameters and the target surface

Parameters

Defaults are the metric values the palette inserts. Every parameter can be driven by an expression or a target.

Points

Point codes are what feature lines, styles and quantity take-off match on — they are the contract this subassembly publishes.
