Share your floor plans in one click

With a shareable link, event sales, planners, and event hosts can share virtual tours, plans, or designs to collaborate in dynamic 3D inside the Prismm platform. Show off rich media, change the linen colors (again) or effortlessly manage and inform everyone of the five late RSVPs that just arrived, all within one link. It’s like being there without lifting a finger to lift the furniture.

Capture feedback from anyone, anytime

Users can quickly pick up the Prismm platform with its intuitive interface. No need to send an email, text, or smoke signal— collaborate over video calls and meet in real-time when you have design feedback or improvements.

Phone a friend

Get help from your close family, friends, or other people important to your event and invite them to your account for free. Get help entering guest information, solicit opinions and feedback on floor plan designs, and request assistance arranging seating charts. What a piece of cake!

Scale quickly with predefined floor plan layouts

Most venues already have their event floor plan layouts uploaded into the Prismm platform. If someone else held an event at the same venue and used Prismm, the event space will be stored and ready for you to use! Not exactly the way you envisioned it? You can easily change the existing event to make it your own.

If a floor plan layout isn’t already in Prismm, it just takes three easy steps to upload it to the platform:

1. The name and address of your venue
2. Dimensions of the event space
3. Perimeter walls of the event space

That’s it! Scanning a new venue for 3D will take a little more time, so this should be one of the first things you do after choosing a venue.

2D and dynamic 3D views of your floor plans

The Prismm platform makes switching between 2D and 3D views seamless. View an entire floor plan from a bird’s eye view, explore it with a first-person perspective in a 3D digital twin, or make detailed edits in a 2D-floor plan. Going between 2D and 3D is easy and can be done at any time at lightning-fast speed, allowing for efficient event planning and design.

Design your tabletops in realistic 3D

Take the guesswork out of designing tabletop arrangements for your event. Prismm’s event floor planning software offers a realistic 3D tabletop designer to create to-scale tabletop and buffet displays within your floor plans. Build designs for dining tables and buffets with options for place settings, flowers, centerpieces, linens, napkins, and buffet pieces, all customizable to your event’s aesthetic. Voila!

Keep everything on schedule.

Do you get nightmares about your event going off the rails? Hey, we’ve all been there. The Prismm platform can give you peace of mind that everyone involved with your event can be kept on track with timelines attached to each floor plan. Invite vendors, suppliers, caterers, and other key personnel essential to your day-of operations to collaborate on all event details from set-up to breakdown.

(Actually) useful event reports

Generate useful reports that can be filtered to meet your needs. Prismm allows users to generate detailed reports from guest lists and floor plans, which can then be shared with vendors and used for planning and logistical purposes. Your floor plan report will dictate your desired layout along with your seating. That way you can be sure that the room is set up how you want it.

Day-of planners and venues will both appreciate seeing a floor plan report detailing the specific layout along with a complete listing of inventory, table breakdown, and seating information. A guest report can also be generated to include details such as meal types, table numbers, and any other relevant information caterers need. Your guest list report can be given to the calligrapher for invitations, place cards, and even for personalized favors.

Showcase your space for instant connection

Venues using the Prismm platform can easily showcase their spaces in dynamic 3D. Bring the entire event team together for immersive virtual site inspections and tour an event via a shareable link accessible from anywhere in the world.
