Construction modules
The trade, built into the modeler.
Seven optional modules that know a trade's products, rules and machines. Each adds tools to the rail, a page of its own, its lists and its export formats — and every one of its operations is an action an agent can call.

Wood
Timber and what is built on it.
Timber is the base: CLT, Timber frame, Stairs and Roofing build on its elements, joints, lists and BTLx export, and need it.

Light-gauge steelHow you buy them
Once, per seat. Yours for good.
- One-time: a module is bought once per seat and does not expire — whichever way you pay for Kozorosa.
- Tried first: every module is in the 5-day trial.
- Where they run: in Foundry today; in Kozorosa for Mac with the desktop release that brings them, free to those who own them.
Honest limits
What the modules do not do.
They pre-size and check; they do not replace a structural engineer's calculation. IFC export is geometry and the elements' classes — there are no storeys or property sets yet. Some rule sets carry their publishers' licences; each library says where its numbers come from.
