Selection

The default and most-used tool — it selects a piece to view or edit its properties, moves it around the canvas, and groups objects together so you can align, merge or mirror several of them at once.

How to select

1. Click the "Selection" button on the left panel or press V — it's also the tool active when the app opens.
2. Clicking an object selects it alone, clearing the previous selection.
3. Clicking empty space and dragging draws a marquee that grabs everything fully inside it: in the screenshot above, a single drag selected both the rectangle and the circle.
4. Dragging an already-selected object moves it around the canvas, snapping to the grid and to nearby pieces' key points.
5. Delete or Backspace removes the selection — the second key is there for Mac, which has no dedicated forward-delete key.

With several objects selected

In the screenshot above, two objects are selected at once — the "2 objects selected" heading unlocks a set of operations not available for a single object:

"Merge"

Builds a single contour from the overlapping area of several pieces — works if at least two selected shapes (circle, rectangle or polyline) actually overlap, not just touch at an edge.

"Group"

Links the objects into a group — from then on it's selected and moved as one, until ungrouped. See the Group article for details.

Alignment — left / center ↔ / right / top / center ↕ / bottom

The anchor piece — whichever was selected first — doesn't move; the rest line up against it along the chosen side or axis.

Visibility, Lock

Quick toggles for all selected objects at once — hide them from the canvas or protect them from accidental moves.

Handy keyboard shortcuts

Some commands for selected objects are faster from the keyboard than hunting through the UI:

Ctrl+C / Ctrl+V / Ctrl+D

Copy, paste, duplicate the selection in place.

Ctrl+A

Select every object on the canvas.

Ctrl+M / Ctrl+Shift+M

Mirror the selection horizontally / vertically — see the Mirror article for details.

Ctrl+] / Ctrl+[

Move the object one layer up / down in draw order. Add Shift to jump straight to the top or bottom.

Ctrl+Shift+T / R / K

Dialogs for moving, rotating and scaling the selection by exact numbers instead of by eye with the mouse.

Ctrl+Shift+D

Array copy — repeat the selection in a row with a set X/Y step.

Ctrl+Shift+U

Same as the "Merge" button in the properties panel.

While dragging, the cursor snaps not just to the grid but to nodes and edges of other pieces too — handy when assembling a multi-piece item where parts need to meet with no gap.
