Trims and skirting

Rooms can have skirting boards, dado rails (two-tone walls above and below), cornices and floor dividers; every opening can have an architrave.

Select a room (its Trims section) or an opening (its Architrave section) and choose a style from the grid of cards in Properties. You can also drag a trim card from the Assets window onto a room in the view. Trims follow the walls round corners, arcs, platforms and flights, and run through openings.

To paint the band under a dado rail, use the Paint tool with Alt+click (see Painting).

A cornice follows the top of each wall. Where a wall has a height of its own (sloped, raised, lowered, or fitted to a roof) the cornice hangs from that top edge, climbing and falling with it and changing slope where the wall does (up and over a ridge), and meets the cornice of the next wall at the corner. Doors and windows that reach it stop it.

A profile is the cross-section of a trim, drawn as points in millimetres. Open the Trim profile editor with Window > Trim profiles, or double-click a trim card in the Assets window.

Action What it does
Drag a point Move it (1 mm / 5 mm steps; Shift is free)
Double-click a line Add a point
Delete Remove the selected point

The editor also has a table of the points, Mirror, Reverse and Scale, and a picture of the profile swept round a room corner as you edit.

Kind Origin and axes
Skirting Origin at the floor and wall corner, x out of the wall, y up.
Dado rail Origin on the wall at the rail height, y up or down.
Cornice Origin at the ceiling and wall corner, x out, y down.
Architrave Origin at the opening’s edge on the wall face; negative x goes into the reveal.

A profile that crosses itself, lies behind the wall or has fewer than two points is not built; the room says so in Problems.

A profile is a portable .ietrim text file. The project keeps them in Assets/Trims/. Import, Save as a file and Save to my library move them between projects and people. The built-in styles are listed as read-only cards to Duplicate and start from.

A room’s skirting, dado or cornice (and a door’s or window’s architrave) picks a custom profile from the same style grid, with a Scale % row.
