Conversion

Ink threshold 200
Minimum wall length 24 px
Room label prefix (used by Number rooms)
Surveyor name (appears on the report)
Imports are stripped to pure black and white before conversion. The converter currently detects horizontal and vertical walls only; diagonals must be drawn by hand.

Amending a converted plan

The converter commits: every wall it is confident enough to keep is drawn as a wall, in one ink. Nothing is left amber for you to approve. Where it has got something wrong, tap the wall and drag, shorten or delete it, or pick Wall and draw the one it missed \u2014 Ctrl+Z undoes anything.

Preferences

Interface
Automatic picks the tablet interface on a touch screen and the desktop one everywhere else. Override it if your machine is both.
