What it does
Space Designer 3D combines a browser-based floor-plan editor, furniture and material choices, measurements and 3D walkthroughs. Its audiences include homeowners and design teams.
Space Designer 3D keeps the drawing and the walkthrough in one browser workspace. Draw walls and openings, furnish the space, then compare the result in 3D. Live room areas and wall lengths give the layout a numerical reference as it changes.
For a homeowner, one measured room is a sensible first project. Use the walkthrough to discuss furniture placement or finishes with another person before expanding the design. The product offers a free-trial entry route. Exported measurements depend on the model supplied and should be checked against the actual site.
The current pricing page lists a free Starter plan with one project, one level, a limited catalogue and 10 rendering credits, plus PNG, JPG and PDF exports. Paid plans expand project capacity and formats such as DXF. This is more specific than the homepage’s trial invitation, so choose access from the current plan table.
