Every setting, explained
Open Settings from your account menu to set units, floor naming, electrical symbols, and your drawing defaults. Here's what each one does.
Settings let you tailor Room Sketch 3D to how you work. Open them from your account avatar → Settings (top-right). Here's every setting, one by one.
Step by step
- 1
Open Settings
Click your account avatar at the top-right and choose Settings. Everything below lives on this one page; changes apply right away, and Back to Designer returns you to your plan.
The Settings page — measurement units, floor naming, electrical symbols, and drawing defaults. - 2
Measurement Units
Switch between ft/in (feet and inches) and m/cm (meters and centimeters). This is display only — it never changes your design; a 12-foot wall is the same as a 3.66-meter wall.
Measurement Units — feet/inches or meters/centimeters. - 3
Floor naming
Choose how floors are labeled: Ground (Ground floor, 1st floor, 2nd floor — UK/most-of-world) or 1st (1st floor, 2nd floor — US). Affects labels only.
Floor naming — Ground-floor or 1st-floor convention. - 4
Electrical Plan Symbols
Turn On to add outlets, switches, valves, vents, and your own uploaded icons to the floor-plan markup. Built for electricians, plumbers, and HVAC techs; leave Off for a standard interior plan.
Electrical Plan Symbols — outlets, switches, valves, and vents. - 5
Drawing defaults
The lower section sets the defaults stamped onto every new room you create. Leave a field blank to use the standard value; numbers take up to 2 decimal places. Existing rooms keep the values they were drawn with.
- 6
Grid Spacing
The distance between gridlines on the canvas (default 12 in / 30 cm). Larger spacing for site planning, smaller for fine detail. The grid is visual only — snapping isn't affected.
Grid Spacing — distance between gridlines on the canvas. - 7
Exterior wall thickness
The default thickness for new exterior walls (default 6.5 in). Thicker for masonry, thinner for lightweight construction. This is only the starting value — once a wall is placed, you can change any wall's thickness individually by selecting it and editing it in the Inspector. Existing walls keep their saved thickness.
Exterior wall thickness — applied to new exterior walls. - 8
Interior wall thickness
The default thickness for new interior walls (default 4.5 in). As with exterior walls, this is just the starting value — after placing a wall you can adjust its thickness individually in the Inspector. Existing walls keep their saved thickness; click Reset next to any field to return it to the standard default.
Interior wall thickness — applied to new interior walls.
Frequently asked questions
Does changing units change my design?
No — units are display only. The geometry is identical; only the numbers shown change.
Why don't new wall thicknesses apply to my existing rooms?
Drawing defaults stamp onto new rooms only. Existing walls keep the thickness they were drawn with — edit a wall directly to change it.
