Changelog
12 November 2026

- Precast floors say their size in the legend.
- A counter batten arrives as deep as its size.
- In Revit, a colleague's drawing that is shared with you can be reloaded like your own.
- In Revit, a project folder on a cloud drive is found on every colleague's computer.

11 November 2026

- When someone takes over editing, you stay on your drawing, which turns read only.
Library
- Switzerland's materials, in Swiss German and in French, with the sizes sold there.
New features
- Switzerland is a region: draw in Switzerland and print the drawing in German or in French, picked from the flag.
- One Swiss flag in the flag list, with its German and French beside it under the hand.

- Drawing tips for Swiss timber walls and pitched roofs.
- The Revit plugin lists the drawings shared with you, in a folder of their own.
- Shared drawings show who last edited each element, in a colour per person, with a small list of names and how long ago; hover a name to see that person's work in colour.
- A request to edit your drawing now appears in the middle of the screen over a softly blurred drawing.
- Read-only drawings show a white sheet with grey boxes, the editor's two tones turned round.
- A small pen marks the names you can edit, on an analysis vector and a component.
- A component picked whole has its own card: rename it in place, edit it, store it in your library, explode it, switch its outline on, and see what is in it.
- The component's bar floats over the drawing, with its name on a soft blur.
- Notes come in five sizes, XS to XL.
- A note can be Normal, Warning or Mute, or No print: shown on the screen and left out of every export.
- On shared drawings one panel lists who changed what and who is editing, with a Request edit button under the names.
- Hovering a name half-tones the rest of the drawing and draws that person's work a little heavier.
- Invited editors get drawing tips too, and the components drawer fits the components it holds.
