Warren/Pratt Truss Bridge

Act as a structural design engineer. Create a 3D solid CAD model of a scale Warren/Pratt truss bridge in millimeters. Units: Millimeters (mm) Overall Dimensions: - Bridge Span (Length): 500 mm - Overall Height: 100 mm - Bridge Deck Width: 120 mm - Topology: Two identical parallel vertical side trusses connected by top and bottom transverse cross-members. Structural Member Profiles: - Main Members: 10 mm x 10 mm solid square bars for all top chords, bottom chords, vertical posts, diagonal braces, and cross-beams. Truss Geometry (Each Side): - Bottom Chord: Continuous 500 mm horizontal beam at base level. - Top Chord: Parallel horizontal beam, 300 mm long, centered above the bottom chord at 100 mm height. - End Posts: Sloped end members angling down at 45 degrees to connect the ends of the top chord to the ends of the bottom chord. - Web Members: Divide the span into 4 equal bay segments. Add vertical posts at each node and alternating diagonal braces connecting top and bottom nodes to form a rigid triangulation network. Cross-Bracing & Deck Framing: - Bottom Cross-Beams: Add 10 mm x 10 mm transverse beams connecting the bottom nodes of the left and right trusses (5 transverse members total). - Top Cross-Beams: Add 10 mm x 10 mm transverse beams connecting the top nodes of the left and right trusses (4 transverse members total). Manufacturing & Output Intent: - All intersecting structural members must be cleanly merged/fused into a unified B-Rep solid model.
