Four-lane composite highway bridge
42 + 60 + 42 m, five welded S355 plate girders under a C35/45 deck; cross girders, bearings, joints, drainage, piers, abutments and bored piles in one multi-sheet project.

Civil Engineering
Model bridges, towers and halls as parametric structures: spans, grids, heights and member sizes are inputs, and plans, sections, position plans and parts lists follow every change. Clients and partners open the model in the browser, without a CAD installation.
Examples
Structures you can open right now
Each model is public and parametric; change spans, grids and member sizes in the browser.
HELIX hyperboloid observation tower
Double-shell space frame on the Shukhov principle with spherical nodes, hexagonal core and spiral stair; radii, segment height and member diameters are inputs.

Capabilities
Rule-based
Grids and spans follow fixed rules, for example a hall width on a 2.5 m grid and frames every 5 m – only buildable variants can be chosen.
Assembly-aware
Girders, columns, bearings, foundations and connections are separate sheets with their own parameters.
Ready for the next step
IFC, STEP, DXF and PDF drawings from the same state; quantities for steel by weight and envelope by area.
Drawings that follow the model
When a span or a grid changes, plans and quantities usually have to be updated by hand. In confBuild the structure is a parametric model: axis grid, spans, heights and member sizes are inputs, and the plan, sections, elevations and the position plan with parts list are derived from it. The video shows a hall growing on its grid while the plan's axes and dimension chains follow.
From structural concept to drawing set
-
01
Set the system
Axis grid, spans, heights, cross-sections and materials as inputs.
-
02
Build the members
Girders, columns, bracing, decks, bearings and foundations as sheets that reference the system.
-
03
Derive the drawings
Floor plan as a horizontal section with axis grid, sections with level marks, elevations and a position plan with parts list.
-
04
Hand over
IFC for BIM coordination, STEP and DXF, parts list and a review link for clients and partners.
Drawings
Position plan
Members numbered and listed with quantities.
Plans and sections
With axis grid, dimension chains and level marks.
Exchange
IFC, STEP, DXF and PDF.
Position plan and parts list from the model
Member positions, quantities and the parts list are read from the same model that the 3D view shows. A changed grid or span updates the drawing, not just the render.
Capabilities
What structural projects use
Steel construction rows
Sections, flat and round bars, cuts and copes, bolt sets with clamping length, end plates, fin plates, base plates and gussets, plus steel stairs.
- Connections as parametric rows
- Position numbers in the parts list
- DSTV-NC export for steel parts
Structural drawing sets
Floor plans, sections, elevations, position and erection plans and shop drawings per member, generated from the declared structural model.
- Axis grid and level marks
- Position plan with parts list
- Vector PDF
Exchange and review
IFC, STEP and DXF for the next tools; a browser link with prepared animations for clients, partners and approvals meetings.
- IFC and STEP
- Erection and exploded animations
What a structural model delivers
A coordinated concept and drawing basis. Structural verification and approval stay with the responsible engineer.
Parametric structure
Grid, spans, sections and connections in one model.
Drawing set
Plans, sections, elevations and position plan.
Quantities
Parts list with weights and areas for costing.
Exchange files
IFC, STEP, DXF and a review link.
Typical uses
- Bridge and tower concepts with variable spans and member sizes
- Steel and system halls with crane runways, platforms and stairs
