Snapping Overview
Snapping constrains the cursor to specific positions while drawing and editing. When a snap candidate is found, the cursor jumps to it and a visual indicator appears. Multiple snap modes can be active simultaneously — the closest candidate wins.
The snap toolbar is in the top toolbar. The master Snap toggle enables or disables all snapping at once. Individual mode buttons toggle each snap type independently. A mode button glows when that mode is actively snapping the current cursor position.
Snap Modes
| Mode | Icon | Description |
|---|---|---|
| Snap (master) | Enables or disables all snapping at once. | |
| Grid | Snaps to the grid increment defined in the Grid settings. The snap increment can be finer than the visible minor grid lines. | |
| Point | Snaps to the control points (vertices) of existing features, tabs, and clamps. | |
| Line | Snaps to the nearest point on any line segment of existing features. | |
| Midpoint | Snaps to the midpoint of line segments. | |
| Center | Snaps to the center of circles and arcs, and to the bounding box center of other features. | |
| Perpendicular | Snaps to the point on a line segment that is perpendicular to the cursor's current position. |
Grid Settings
Select the Grid node in the feature tree to edit grid settings in the properties panel.
| Setting | Description |
|---|---|
| Grid Extent | The total size of the visible grid area. Increase this if your stock is larger than the default grid. |
| Major Lines | Spacing between the heavier grid lines. Typically set to a round number like 10 mm or 1 inch. |
| Minor Lines | Spacing between the lighter subdivision lines. Must be less than or equal to the major spacing. |
| Snap Increment | The grid snap resolution. Can be finer than the minor line spacing — for example, 0.125 in snap with 0.25 in minor lines. |
| Visible | Toggles grid line visibility. Snapping still works when the grid is hidden. |
Axis Lock
While drawing or moving, press Alt / Option to cycle the axis lock: first press locks to the X axis, second press locks to the Y axis, third press releases the lock. The current lock state is shown as a visual indicator on the canvas.
