Once you have a plan, everything in it is editable. Here's a tour of the tools.
Selecting things
One item — click it. The inspection panel opens on the right with that item's properties.
Several specific items — hold Shift and click each one. Shift-click toggles, so clicking something already selected removes it again.
A whole row of walls, to move them together — hold Cmd (Mac) or Ctrl (Windows) and click a wall. Maket selects that wall plus every wall connected in a straight line with it, and you can drag the whole run as one piece.
This is how you push a long wall out to make a room bigger. Without it, a wall made of several segments has to be dragged a piece at a time, and the pieces come apart.
All the furniture in a room, as a group — hold Cmd or Ctrl and click any piece of furniture. Everything in that room gets selected, so you can move the whole arrangement at once.
Adding a group to what you already have — hold Shift as well as Cmd/Ctrl. On its own, Cmd/Ctrl-click replaces your selection with the new group; add Shift and it joins what's already selected.
Selecting an area — drag across empty canvas to draw a box around everything you want. Hold Shift while you drag to add that box to your existing selection.
Clearing your selection — click any empty part of the canvas.
On the canvas
Resize a room — select it and drag any resize handle to move that section of wall.
Move a wall — click any wall segment to select it, then drag to reposition. Press delete or backspace to remove it.
Drag a corner — corners can be dragged where the shape allows it, which is useful for angled walls and for tidying up after drawing. The handle appears when the wall or room it belongs to is selected, and snaps to nearby corners.
Move doors, windows and furniture — click and drag.
Rotate furniture — select it and use the rotate handle.
Resize furniture — some items resize: kitchen counters and cabinets, sinks, bathroom vanities and staircases. Select one and square handles appear wherever you can drag. The cursor shows which direction each handle moves.
Remove furniture — select it and press delete or backspace.
Top toolbar
2D / 3D — switch between the layout editor and the 3D view.
Floor selector — switch between floors on a multi-floor home.
Settings (the gear) — switch between metric and imperial. Your choice is remembered for that project.
Undo / Redo — step backward or forward through your changes, in both 2D and 3D.
Bottom toolbar
Furniture — add furniture to any room. Use the search bar if you know what you're looking for. Names can differ between similar items, so if "couch" doesn't find it, try "sofa".
Structure — add doors, windows or stairs.
Select — the default mode for clicking and moving things.
Draw wall — draw new walls and create new rooms, including over existing walls. Double-click a node or close a room to finish, then click Select to leave draw mode.
Zoom controls — bottom-right of the canvas.
Inspection panel
Whatever you select, its properties appear on the right.
Floors and rooms
Floor area and dimensions
Room type, and Furnish room once a type is set
Remove a room
Walls
Wall length and dimensions
Wall thickness — including across several walls at once
Remove a wall
Invisible toggle — hides an internal wall while keeping the spaces on either side as separate rooms. Use it for open-plan kitchens, dining and living areas. Only works on internal walls that have no door or window in them.
Doors and windows
A door or window has to be placed in a wall before you can change it. If it isn't properly attached to one, you won't be able to set its size or which way it opens — there's no wall for Maket to fit it into and no room for it to open onto.
Once it's sitting in a wall, select it to adjust:
Width and Height
Which way it opens — flip or rotate it to swing the other way, or onto the other side of the wall
Windows also have linked Distance from ceiling and Distance from floor — change one and the other updates, so the window keeps its size
Furniture
Rotate or flip
On kitchen counters and cabinets, swap finishes — the countertop and the cabinets are controlled separately
Editing in 3D
You aren't limited to 2D. In 3D you can select walls, windows, doors, furniture and rooms, and the inspection panel shows the same properties it does in 2D.
Walkthrough — the room you're standing in is selected by default. Hover and click to select something else; click-and-drag still pans your view.
Isometric — click a room's floor to select and isolate it, then use the back button to return to the full floor.
Massing — click any item on any floor. Selecting something also changes which floor you're on, so you'll land there when you switch back to another view.
