Features

InterFab is made up of modules that cover the whole of prefabricated steel structure production. Each module works on its own, and together they share the same model.

Available

3D Drawing Engine

Model prefabricated steel structures in the browser.

A floor-by-floor drawing environment that tracks every structural element by its own identity. Walls are handled as whole units, and doors and windows follow the life cycle of their wall. Measuring, cut planes, exploded views and walkthrough navigation are built in.

Highlights

  • Editing that preserves the identity of columns, beams, walls and anchors
  • Cut planes, exploded view and walkthrough camera
  • Shortcut schemes for hands used to AutoCAD and SketchUp
Available

Drafting & Output

Produce the technical drawings that go to the shop floor.

Drafting sets work with viewports that hold independent camera state, a title block defined as a set-level template, and model references that update atomically. Automated and manual dimensions have separate ownership models, so a dimension you placed by hand is not lost when the model updates.

Highlights

  • Independent camera and view state per viewport
  • Set-level title block templates
  • Separate handling of automated and manual dimensions
Available

Take-off & Bill of Materials

See the bill of materials the drawing produces, live.

The bill of materials is not a separate table that reads the drawing — it is a view derived from the model itself. Profile sections, connection elements and cladding areas are aggregated per element and can be compared across revisions.

Highlights

  • A take-off that updates itself as the model changes
  • Breakdown by profile section, connection element and surface
  • Handed to costing and quoting as an immutable snapshot
Available

Quoting & Costing

Price the take-off and turn it into a commercial document.

On the costing side you get material items, operations and recipes with multi-currency price management. On the quoting side, commercial terms, service scope and the customer snapshot are frozen independently of the drawing: changing the model after a quote is sent does not alter the document you already sent.

Highlights

  • Costing based on materials, operations and recipes
  • Multi-currency pricing and exchange rate handling
  • Quotes frozen with a customer snapshot

Visualisation

Produce client-facing imagery from the same model.

Generate presentation imagery without exporting the model to separate visualisation software. With the augmented reality viewer, your client can see the structure at scale on their own site.

Highlights

  • Background render queue for presentation imagery
  • Augmented reality viewer on mobile devices
  • Imagery exported straight into the quote attachment
Coming soon

Production & CNC

Connect the take-off to shop orders and CNC output.

A module covering factory work orders, cutting optimisation and CNC/CAM export. Still in development — talk to us about the roadmap or joining the pilot.

Highlights

  • Cutting lists and offcut optimisation
  • Factory work order tracking
  • CNC/CAM machine output

It speaks the language of the trade

InterFab is not a general-purpose CAD program. Concepts such as anchor, profile section, structural element, drafting set and quote project exist as real definitions inside the software. That is why, when you move a column, the software knows what that does to the take-off, the connections and the cost.

Let's run it on your own project

In about half an hour we model one of your real projects in InterFab and produce its take-off and cost together with you. No preparation needed on your side.
