Drop a guide

Guides are infinite horizontal or vertical reference lines you drop on the canvas. The drawing tools snap to them, so they're the right way to commit a known reference (a property line, a centreline, an existing wall location captured from a site measurement) before drawing the geometry that lines up with it.

Drop a guide on desktop

Right-click empty canvas and pick either Add Horizontal Guide here or Add Vertical Guide here. The guide drops at the right-click position and extends infinitely in its axis. See the canvas context menu for the full list of entries that menu can show.

Drop a guide on mobile

Guides on mobile are dropped through the Tape Measure tool's precision pad:

1. Tap the Tape Measure icon in the left toolbar.
2. Tap roughly where you want the guide. The endpoint adjust pad opens with a crosshair.
3. Nudge the crosshair onto the exact position you want.
4. Tap the H Guide chip (with a + icon) to drop a horizontal guide at the crosshair's Y position, or the V Guide chip to drop a vertical guide at the crosshair's X position.

The H Guide and V Guide chips only appear on the precision pad while the Tape Measure tool is active. They're hidden in other flows (the wall tool's precision pad doesn't offer them).

What guides do

• Drawing tools snap their cursor to nearby guides. The default snap distance for guides is intentionally tighter than other targets, so infinite lines don't grab your cursor from across the room.
• Guides feed alignment hints to other entities. When you're drawing a wall whose endpoint aligns with a guide, the alignment indicator appears.
• Guides persist with the project. Save and reopen the file and your guides come back where you left them.

Hide or show guides

Toggle Guides in the Layers section of the entity panel (desktop right rail or mobile info button) to hide guides without deleting them. Useful for a clean review pass or a print of just the geometry.

Tips

• A guide is a planning aid — it shouldn't end up in the printed plan. Toggle the Guides layer off before printing if you don't want them on the page.
• For a one-off measurement reference rather than an infinite snap target, drop a measurement mark via Tape Measure instead. Measurement marks are points, not lines.
• To delete a guide, right-click it on desktop or long-press it on mobile. See Guide context menu.
• On mobile, after a guide is placed, tap it to open the guide edit panel for delete and (when the guide has an origin) distance editing.
• The active placement flow produces horizontal or vertical guides. Pin guides — single-point guides that render as a small marker — show up in the entity panel and snap registry but don't have an active create path in v1; if you see one, it most likely came from an imported or older project.
