Use the grid
Set a visual reference spacing and decide whether drawing gestures snap to it.
Grid visibility and grid snapping are separate. Showing grid lines does not require Grid snapping to be on, and hiding the lines does not itself disable snapping. Check the snap palette’s state before relying on a placement.
Show the grid and set its spacing
Open Display in the canvas menu bar. Turn on the grid where the current editor offers it, then choose Grid Size. The choices are formatted for the project’s measurement system. Do not assume the same numeric default or spacing in metric and imperial projects.
Choose how grid lines are drawn
Grid Visuals offers Adaptive and Fixed. Adaptive adjusts the visible density as you zoom; Fixed displays the chosen visual spacing. This visual choice is not a change to an object’s geometry.
Enable Grid snapping
Show the snap palette through Panels where necessary. Turn on the snapping master and Grid there. Shift+S toggles the shared snapping state. The available snap controls depend on the active editor.
Combine the grid with geometry snaps
Grid, object-point and direction constraints can be active together. Watch the active snap marker and its label to see which candidate is being used. Do not assume every gesture must choose a grid intersection when another applicable snap wins.
Temporarily suppress snapping deliberately
Use the palette’s Snapping off for next gesture action for one gesture, or hold Ctrl for Snapping off while held, as shown in snap help. Rest on a point or edge for 0.6 seconds by default to pick it up as a reference; rest again to drop it. Esc clears picked-up references.
