Step-by-step how-tos for builders and engineers. In this article we walk through what we have learned on real projects, with numbers you can use.
Common mistakes
Mixing units
A model drawn in centimetres and exported as millimetres produces frames ten times too small. Check the export settings every time.
Ignoring services
Plumbing and electrical runs need pre-punched holes in the right place. Add them to the model, not with a drill on site.
Skipping the test panel
Form one panel and dry-fit it. Ten minutes of checking saves a day of re-forming.
The checklist
Geometry
- All walls are closed polylines with consistent thickness.
- Openings are real voids, not just symbols on a drawing.
- Levels and datums are named and match the structural drawings.
Profiles and gauge
- One profile family per element type (C89, C140, U-track).
- Gauge assigned per wall, not guessed by the detailer.
- Lip and web sizes match the tooling on your machine.
Connections
- Pick a connection rule per junction: L, T and X.
- Confirm screw and bolt hole positions with the fabricator.
- Export a test panel before releasing the whole job.
