Floor Plan Features

Drawing Tools

Gridsnap's wall drawing tool snaps to a configurable grid so every line lands exactly where you intend it. Endpoints auto-connect to adjacent walls, keeping your floor plan watertight with no gaps or overlaps. Doors and windows are placed directly on walls with configurable frame depth and swing position. Smart hit detection lets you select, move, or delete any element without accidentally touching a neighbouring one — ideal for dense plans where walls, doors, and furniture sit close together.

Wall tool with adjustable thickness and snap-to-grid alignment
Single, double, and sliding door types with configurable frame depth and hinge position
Window tool with controllable sill depth and placement along any wall segment
Smart hit detection prioritises the element closest to the cursor
Endpoint snapping automatically joins wall ends for a clean, closed plan
Configurable grid size (e.g. 50 mm, 100 mm, 250 mm)

Furniture Catalog

Drop in furnishings from a built-in catalog of 30+ items spanning every room in the house. Each piece can be rotated in 1° increments and resized to match your exact specification, so a 2 400 mm sofa stays 2 400 mm on the plan. Corner sofas render as a true L-shape, giving an accurate footprint for tight living areas. Group multiple items to move or copy them together — useful when staging the same layout across multiple floors. See use cases for how interior designers and homeowners put the catalog to work.

30+ catalog items: sofas, armchairs, dining tables, beds, desks, kitchen appliances, bathroom fixtures, and more
Rotation in 1° increments via handle or numeric input
Custom width and depth sizing per item
Corner sofa with L-shaped geometry
Box-select multiple items and move or copy as a group
Duplicate items with a single keyboard shortcut

Dimensions & Annotations

Dimension lines anchor directly to wall endpoints and update automatically whenever a wall is moved or resized — no manual re-entry required. Labels render at scale so they remain readable at every zoom level and at any export size. Text annotations can be placed anywhere on the canvas for room names, area notes, or material callouts. All measurements are stored and displayed in millimetres for professional accuracy consistent with architectural drawing conventions.

Automatic length calculation in millimetres
Scale-aware rendering: dimensions stay legible at every zoom level
Free-placement text labels for room names and notes
Dimension style (tick marks, arrowheads) consistent across exports

Multi-Floor Support

Add as many floor tabs as your building requires and switch between them instantly. Activate the ghost-floor overlay to see the floor above or below at reduced opacity, making it easy to align stairwells, structural walls, and service runs across levels. Staircases placed on one floor link to the corresponding landing on the adjacent floor. Each floor can be renamed, reordered, or deleted independently. Multi-floor plans are a good fit for the contractor and architect use cases.

Unlimited floor tabs per project
Ghost-floor overlay shows adjacent floor at adjustable opacity
Linked staircase objects span two floors automatically
Per-floor rename, reorder, and delete
Each floor exported as a separate sheet in PDF or as a separate DXF file

Export: DXF, PDF, PNG

Gridsnap's DXF export organises every element onto named CAD layers so the file opens cleanly in AutoCAD, BricsCAD, LibreCAD, or any other DXF-compatible software. The PDF export adds a title block with project name and date, a printed scale bar, and supports A4, A3, and A2 page sizes at standard scales (1:50, 1:100, 1:200) or scale-to-fit. PNG export produces a high-resolution raster image suitable for presentations, property listings, or sharing with clients who don't have CAD tools. All export formats are included free with no watermark.

Workflow & Productivity

Every tool in Gridsnap has a keyboard shortcut so your hands rarely need to leave the keyboard. Full undo/redo history means mistakes are never permanent. Copy and paste works across floors, letting you reproduce a bathroom layout on every level of a multi-storey plan in seconds. Import a scanned or photographed plan as a reference image overlay, scale it to the canvas, and trace over it to produce an accurate digital drawing. The move tool accepts a direct distance input for nudging elements by an exact number of millimetres.
