Measurements & properties

Read wall lengths, areas and room labels; set units and precision; and fill in the title-block drawing properties.

Every drawing carries real-world dimensions. This page covers the measurements shown on the canvas and the title-block metadata that turns a sketch into a document.

Wall length labels

Each wall shows its length on the outside of the room, in your chosen unit:

• The label is rotated to align with the wall, but never drawn upside-down — it flips so it always reads left-to-right or top-to-bottom.
• It sits just outside the wall’s outer face, with a small fixed gap, and stays a constant size as you zoom (only its distance from the wall scales).
• It always shows the full wall length, even when the wall has a door or window — a 4 m wall with a 1 m door is still 4 m.
• The “outside” is found per wall by testing which side falls outside the room boundary, so it’s correct even on concave (L-shaped) rooms.

Areas, perimeters and room labels

• Area and perimeter are computed automatically from each room’s boundary.
• Room labels (the room name, in uppercase) are drawn at the room’s area-weighted centroid, so the label lands inside even an L-shaped room. Room labels are a setting (off by default).

Units & precision

Set in Settings:

Geometry is always stored in metres; units only change the display. See Coordinate system & units.

Ceiling height

Each room has a ceiling height, used for volume, heat-load and the 3D engine. Set it per room where they differ — a vaulted living room versus standard bedrooms.

Drawing properties (title block)

Open Menu → Properties to fill in the title block that appears on exports:

Edits are buffered — Save commits them, and closing with unsaved changes prompts you first, so you never lose a half-finished title block. Complete title blocks make exported PDFs look professional and keep revisions traceable.
