# VenuePreview vs Prismm for wedding planning

Prismm, formerly AllSeated and now part of Cvent, is a professional event design platform: floor plans in 2D and 3D, seating charts, guest lists and collaboration, sold to venues, planners and vendors. Because it sells to wedding venues and planners, your venue or planner may already use it. VenuePreview is a couple's tool for an earlier question: what will the venue look like decorated? You upload photos of your empty or undecorated venue, choose a style and colors, and get visualizations of it decorated. Use VenuePreview to settle on the look, and Prismm, or your planner's copy of it, to lay out the room.

## VenuePreview vs Prismm: how they differ

- **A decorated look or a working layout**: Prismm is built for laying out an event: you design in 2D, 3D or both with precision floor plans and templates, arrange seating and manage guest lists, with real-time collaboration in the cloud. VenuePreview answers the earlier question of style: how your venue looks decorated in the colors and theme you are weighing.
- **Where the picture comes from**: Prismm works from a model of the space. It recommends 3D scanning the venue early, or entering its name, address, dimensions and perimeter walls, and its 3D views show that modeled space. VenuePreview starts from photos of your own venue, empty or undecorated, so the visualizations show the room you toured.
- **Seating and guest lists**: Prismm handles the parts of planning that come after the look is chosen: floor plans, seating charts and guest lists shared between the people running the day. Its wedding page says planners can collaborate with couples (and their in-laws) in it. If you need a seating chart, Prismm is the tool for that job.
- **Cost and who pays**: Prismm, sold as Cvent Event Diagramming, has a free plan for 1 user and 3 events, then Standard at $480 a year, Pro at $150 a month and higher tiers, as of October 2026. Photo-realistic 3D is listed only on the custom Enterprise plan. VenuePreview is a one-time purchase for a single venue upload, starting at $19 one-time for 40 venue visualizations.
- **Detail of the decor**: Prismm's floor planning page mentions adjusting linen colors, and its homepage mentions table settings and 10,000 furniture and design objects; florals, centerpieces and draping are not mentioned. VenuePreview visualizations show the decorated space, for example table settings, lighting and floral arrangements.

- **Prismm**: Prismm, formerly AllSeated, says it is now part of Cvent. It lets venues, planners and vendors design events in 2D, 3D or both, with floor plan templates, seating charts, guest lists, table settings and a library of 10,000 furniture and design objects, and it recommends 3D scanning a venue early. It is sold as Cvent Event Diagramming, with a free plan and paid tiers from $49 a month as of October 2026; photo-realistic 3D comes with the custom Enterprise plan.

## Which one fits your work

**Choose VenuePreview when:**
- You are the couple and want to see the venue decorated before booking decor
- You are choosing between styles or color schemes
- You have photos of the venue but no floor plan
- You want a one-time purchase rather than a plan

**Choose Prismm when:**
- You or your planner need a floor plan and seating chart
- Your venue already has its space in Prismm
- You need guest lists and collaboration with vendors
- You want a 3D model of the space

## How to use both for one wedding

1. Ask your venue or planner whether they already have your room in Prismm.
2. Upload photos of the empty room to VenuePreview and compare two or three styles and color schemes.
3. Pick the look, then share the visualizations with your planner.
4. Have the planner build the table layout and seating chart in Prismm around that look.
5. Bring both to your decor and floral meetings.
