Truss
Pitch
Truss is a web app that quickly creates standard concert stage truss segments, the aluminum truss that holds up concert lights. It includes variations and options, and download buttons for a 3D model, a mesh, or a layout file.
How it works
The workbench has a 3D preview you can orbit by dragging and zoom with the scroll wheel. Focus stage, Inspect lights, and Overview icon buttons reframe the camera. If 3D rendering is unavailable, the profile dimensions and the layout export still work.
A live triangle count shows the entire scene, plus separate counts for truss and supports, room and audience, and equipment, along with the truss module count and the profile envelope. The count covers model geometry only. Helpers are excluded. A maximum count is also shown at the highest mesh detail.
Profiles and views
Three truss profiles: Box, Triangle, and Ladder. They use the common 290 mm professional profile family as a dimensional reference: 50 mm main tubes and 20 mm braces. Tube wall thickness is not modeled. Brace spacing, connector collars and corner nodes are visual proposals, not exact product replicas.
Four preview layouts: Venue, Single piece, Snap a run, and Stage frame.
- Venue: Club, Theater, or Arena, in Small (10 x 12 m), Medium (18 x 20 m), or Large (28 x 32 m), and Indoor or Outdoor. Roof crossbars range from 0 to 6, and start at 1. Indoor venues can use rear-wall ties. Outdoor venues can use a canopy.
- Single piece: one module of the selected profile.
- Snap a run: a row of snapped pieces, from 1 to 6 (default 3), whose matching end sockets attach exactly, without a gap.
- Stage frame: the stage structure, with optional equipment. Module length is locked in this view, and the light count is limited to 4.
Options
- Module length: 0.5, 1, 1.5, 2, 2.5, or 3 m. The default is 2 m.
- Finish: Aluminium or Black. The default is Aluminium.
- Mesh detail: Near (8-sided chords), Middle (6-sided chords), or Far (4-sided chords). The default is Near.
- Equipment, on Venue and Stage frame: Lights on or off, as a moving-head wash or a moving-head spot, in counts of 0, 4, 8, 12, 16, or 24 (default 4). Audio and Screen can each be turned on or off.
- Show snap sockets can be turned on or off.
This is a digital game-art tool, not a physical rigging or load calculator. Fixture, speaker and venue models are original simplified artwork, not manufacturer CAD or branded replicas.
UI
Truss uses the Hexapuss Drip look from the UI app preset, with title tracking of -0.05em. The Hexapuss Drip font is used on the TRUSS title only: 48px on a phone up to 72px on desktop, uppercase, line height 1.05, in white with a purple glow. Everything else is Oswald. Number readouts use tabular digits, not a monospaced font.
The selected profile card is orange. The selected view and finish segments are purple. Toggles are green when on. The dropdown focus ring is white (--sgu-focus), because red is for recording only.
Controls in the app:
- Dropdown
- Segmented buttons
- Toggle switch
- Stepper (- n +)
- Profile card picker
- Icon button
- Primary and secondary action buttons
- Section label
- Collapsible references section
- Stat rows
Export
Current downloads:
- Download 3D model, as a GLB file. This is the primary action button.
- Universal mesh, as an OBJ file.
- Save layout, as a JSON file.
Planned, not current: FBX, a separate glTF file (.gltf), STL, and 3MF.
The current 3D and mesh files are named from the app version, the profile, and the view, for example truss_v004_box_venue.glb. The layout file is named truss_v004_layout.json. Layout changes stay in the browser unless they are downloaded.
