Light and fast.
Moves the way you expect.

Light enough to run the moment it opens. The only gesture to learn: grab and move.

Recording: a canvas card is dragged onto a 3D wall, an outline shows where it goes, and it hangs there

Drag it into the view.

Pick up a card and an outline shows where it will go. On a wall or on the floor, just drop it.

Recording: moving a work on the wall shows guide lines to other works and snaps into line

Recording: several works are selected, and the align-height and even-spacing buttons line them up

Guides appear. It snaps into line.

Centers, tops, bottoms and even spacing show guide lines and snap. Select several and even out the gaps with one button.

Recording: a plinth is resized with its corner handles and turned with the round handle

Grab to resize and rotate.

Corner handles change the size, the round handle turns it. Dimensions show as you go.

Split view recording: 3D and plan side by side; moving a plinth in one moves it in the other

Move it in 2D, 3D follows.

Put the plan and 3D side by side and edit in either. Move something in one and it moves in the other.

Recording: a floor plan image is loaded, scaled from two points of a dimension, and traced into a room

From a photo of a plan to a room.

Place, scale, trace. Just follow the steps. Common lengths are one tap away.

Recording: a 3D model is loaded, the rooms to import are chosen, and the walls rise

Walls rise from a 3D model.

Load STL, OBJ, GLB or DXF and the rooms and walls are found automatically. Just tap the rooms to import.

The elevation window: pick a wall on the plan and its elevation appears

The work list, grouped by wall with sizes and hanging heights

Drawings and work lists, ready to use.

Pick a wall on the plan to get its elevation. The work list is grouped by wall, with sizes and hanging heights.

One plan,
everyone at once.

Just send the link. The other person can edit right away.

Three people editing at once: other people’s name tags and cursors move, and guide lines appear as a work is moved — **Names and cursors**See who is working on what, as it happens

Saving and your data

If you do not sign in, plans are saved on this device, inside the browser. Clearing the browser's history or site data deletes them. In a private window they are gone when you close it.
Sign in with Google and plans are auto-saved to the “Gallerydraft” folder in your own Google Drive, so you can pick up where you left off on another device.
Only when you use a share link or co-editing does the plan pass through the cloud. It is deleted when you stop sharing or the link expires.
To keep your own copy, use “Save to file” in the app to export a .json.
