Quick Answer: What's a good Space Designer 3D alternative?

What RoomSketch3D is
RoomSketch3D is a floor planner you carry with you: draw the plan on your iPhone while you measure, refine it on the iPad, and open the same design in a browser at your desk. Walls, doors, windows, stairs, and furniture are all to scale, with dimensions in feet-and-inches or metric.
When it's done, export a clean image or PDF — with or without furniture, with dimensions — for the contractor, the landlord, or the listing. One purchase covers every device.
Built for decisions that cost money
Handing off
Export a dimensioned plan as an image or PDF for the contractor, the landlord, or the movers.
Moving
Plan the new place before the truck is booked — every piece has a spot on move-in day.
Remodeling
Test the island, the range, the wall you want to open up — before anyone picks up a tool.

Smart Flow Check reads your plan and flags walkways, door swings, and clearances that are too tight — before you commit to the layout.
