Everything a small practice actually draws.
Fourteen element types with their own dialogs, IFC classes, quantities and 2D symbols — and the documentation pipeline that turns them into a drawing set.
Elements.
Walls & openings
Draw a chain, and the corners mitre themselves and stay mitred. Windows and doors live in the wall as parameters, so nothing breaks when the wall moves.
Roofs
Not just rectangles. An L, a U, a plan with a wing — the hips, valleys and ridges are computed from the outline, so complicated roofs stop being a modelling exercise.
Floors & stairs
The parts of a building that are tedious to model and easy to get subtly wrong. Draw the walking line and the treads, landings, soffit and the opening in the slab above follow.
Structure
IPE, HEA, HEB, UPE, angles and hollow sections from the catalogue — with joints cut to follow the profile, not sliced flat.
Services
Ten systems, product catalogues, bends and tees that appear where they belong, and connection ports that snap to the fixtures.
Output.
Documentation
Plans per storey, named sections, hatching by material at your drawing scale, schedules, and a LayOut file at the end of it. This is where the SketchUp ecosystem stops.
IFC
Material layers, openings linked to their fills, quantities computed from the geometry — and a check that stops two elements collapsing into one in the viewer.
