Why Choose Floors.live
Choose where your plans go next
Cvent is moving Prismm customers onto Cvent Event Diagramming, where every paid plan carries a 12-month commitment. Since your Prismm templates need rebuilding either way, you can rebuild them somewhere independent that bills month to month.
Month to month, or pay per event
Floors.live bills monthly and you can cancel anytime: Starter is free, Planner Pro is $69/month and Studio is $129/month. Would rather not subscribe? Your account includes 10 free editing minutes to try it, then you can unlock an event for $20 — and credit never expires.
Design in 2D, walk it in photorealistic 3D
Lay out tables, stages and dance floors in the browser-based 2D editor, then switch to the photorealistic 3D view and walkthrough to check sightlines — nothing to install. Share it as a link your client opens without an account.
Seating and collaboration built in
Import a guest list, set constraints and auto-assign seating across your tables. Collaborators edit the same plan in real time with per-object sync.
Starts from the real venue drawing
Import DWG files (AutoCAD R13–2025) directly in the browser — processed locally, never uploaded — or calibrate a floor plan image to the room’s true dimensions. Export to PDF or PNG with a capacity summary.
Switching from Prismm
- 1
While you can still edit in Prismm (through June 2027), export or screenshot the layouts you want to keep. That gives you a reference image of your current Prismm layout.
- 2
Upload it as a background image in Floors.live (JPG/PNG, or an image from a URL). If you have the venue as a DWG file, import it directly — CAD import runs in your browser and files are never uploaded.
- 3
Calibrate the scale to the venue’s real dimensions with the built-in scale calibration tool, so every table and aisle measures true.
- 4
Rebuild the layout with the object library, then switch on the photorealistic 3D view to check sightlines and share a link — your clients don’t need an account to view it.
Most venues can also give you a DWG or a floor plan image — either works as your starting point in Floors.live.
