Monet vs Gemini: AI Event Floor Plans Compared
What Gemini and Monet are each built to do with an event floor plan, and how to check both on your own venue.
This guide sets out what Gemini and Monet are each built to do with an event floor plan, from their own documentation. It shows where Gemini is the better choice and where Monet is. It ends with a sample brief and a checklist, so you can compare both on your own venue.
Planners now ask a general assistant for a floor plan first. This guide puts a Gemini event floor plan beside a layout from Monet. It uses what each tool's own documentation says it does. It covers who each tool suits, what to check before you rely on either, and a method you can run on your own venue.
Why compare Gemini and Monet
Gemini is a general multimodal assistant, which means it takes text, images and files as input. Monet is a spatial planning tool for events. They answer different questions. So the first question is which one returns a layout a planner can build from. The second is which jobs around the layout each one does better. The same questions apply to ten AI floor plan generators.
What Gemini is built to do
Gemini reads what you upload. Its help page on files lists documents, spreadsheets, photos, video and code, with up to 10 files in one prompt. It makes and edits images with its Nano Banana image models (Gemini image generation). Its Canvas space writes code and previews HTML and React prototypes (Google).
For planners, that covers real work. Gemini can digest a venue pack and draft and tighten the brief. It can check capacity sums and write the run of show. It can also translate supplier documents and make a mood image for the client. For these jobs Gemini is the better choice. Monet is a layout tool, not a writing assistant.
What Gemini is not built to do
None of those pages describes a floor plan tool. Gemini reads a drawing as an image or a document. It may read the labels and dimensions printed on a sheet, but reading a drawing is not measuring it. An image it makes is a picture, with no reliable scale.
Code is the one route that can return real geometry. Gemini can write Python that uses ezdxf, a library that creates DXF files. Someone must then run the code and check the file in CAD. So a Gemini layout needs three checks before anyone builds from it. It must sit on the real room at true scale. It must keep the aisles and exit paths in the brief. It must also survive a late change without breaking.
What Monet is built to do
Monet builds AI layouts from a venue plan and a brief, in minutes and to scale. You start from a plan in its venue library or upload the venue's own PDF or DWG, so nothing is redrawn. Its checks re-run after every change. They cover exit clearance, temporary structures in the main walkway and crowd flow. They also cover noise on nearby booths, a carbon estimate per layout and spatial occupancy.
The same project gives 3D renders and walkthrough videos, plus production-ready plans and elevations. One change regenerates the plan, the renders and the drawings together. Files export to DWG, DXF, PDF, JPG and GLB, so a venue or crew can open the drawings in CAD. The checks flag problems while you work. The venue and the local fire authority still approve the plan.
How to check a Gemini event floor plan yourself
Use a room where you know every dimension. Your own venue's DWG works, and so does a simple test hall you draw in CAD. One useful test hall is 60 x 40 m on a single level. Issue it as a DWG in millimeters and as a vector PDF at 1 to 200 with a scale bar. Give it four 2.4 m exit doors, two on each long side. Put a 4 m loading door on the east wall and the main entrance on the west wall. Add two 0.6 m square columns on the center line, 20 m and 40 m from the west wall. Write down ten distances you can measure later, such as the overall size, each exit width and the column positions.
Then paste the same brief into both tools, word for word.
"One-day trade show in the attached hall. Peak of 600 people on the floor. 30 booths of 3 x 3 m and four 6 x 6 m island stands. A seminar area of about 12 x 10 m with 100 seats in rows facing a 6 x 3 m stage. Registration at the main entrance with two queues. A catering area of about 150 m2 with 20 high tables. Main aisles 3 m wide, cross aisles 2 m. Keep every exit, and a 2 m path to it, clear. Nothing within 1 m of a column. Priorities in order are exits and aisles, seminar sightlines, island-stand visibility, catering flow."
In Gemini, try three routes, each in a fresh chat. Ask for a dimensioned description with a coordinate table. Then ask for a top-down image, with the PDF as reference. Then ask for code that draws the layout at 1 unit = 1 mm. In Monet, upload the DWG or PDF and paste the brief. Send each tool the same follow-ups, in order and only where needed.
- "Use the attached plan at its true scale."
- "Make main aisles 3 m and cross aisles 2 m."
- "Keep a 2 m clear path to every exit."
- "Keep everything 1 m from the columns."
- "List every assumption you made."
Last, send both tools the same late change. "Move the seminar area to the opposite end of the hall and add four 3 x 3 m booths. Keep everything else." Then open every output in CAD at full size over the venue drawing and work through this table.
- Uses the real venue: Measure your ten known distances on the overlay. An output that cannot be overlaid is not to scale.
- Matches the brief: Count booths, island stands, seats, stage, catering and registration.
- Keeps the rules: Measure main and cross aisles, each exit path and the clearance around columns.
- Survives the change: Note what moved, what broke and how long the fix took.
- Reaches the crew: Note whether you got a DWG or DXF at true scale, a scaled PDF or only an image.
- States its guesses: Read the answer to the last follow-up for anything the tool assumed.
Run each generative route more than once, each time from a fresh chat, because answers vary between runs. Keep every file, so a colleague can check your reading.
Which tool for which job
- Drafting and tightening the brief. Better choice: Gemini. Why: A writing and reasoning job.
- Reading a long venue pack. Better choice: Gemini. Why: Reads documents, spreadsheets and photos.
- Capacity sums and the run of show. Better choice: Gemini. Why: Arithmetic and writing.
- A mood image for the client. Better choice: Gemini. Why: Makes and edits images from a prompt.
- A layout on the real room at true scale. Better choice: Monet. Why: Builds on the uploaded PDF or DWG.
- Renders and walkthroughs in the room. Better choice: Monet. Why: Made from the same to-scale layout.
- Drawings and CAD files for the crew. Better choice: Monet. Why: Plans, elevations and DWG or DXF exports.
- A late change across every file. Better choice: Monet. Why: One change regenerates plan, renders and drawings.
Using both
Split the work by job. Gemini takes the brief, the numbers and the words. Monet takes the layout, renders and drawings, and a person signs off. Start with the prompt guide for event floor plans.
Frequently asked questions
Can Gemini make an event floor plan?
Gemini can describe a layout, make an image of one and write code that draws one. None of these is a dedicated floor plan tool. So open any result in CAD over the real venue drawing, at full size, before you rely on it. Measure the aisles, the exit paths and the clearance around columns.
Can Gemini read a venue floor plan PDF?
Gemini accepts PDFs and images, and it may read the labels and dimensions printed on them. But reading a drawing is not the same as measuring it. Lay any output over the original DWG at full size and measure a few known distances to check the scale.
Is an AI-generated floor plan safe to send to a venue?
Not without checking. Measure every exit width, aisle and clearance against the venue drawing. The venue and the local fire authority approve the final plan. Tools with built-in layout checks flag breaches earlier, but a person still signs off.
How can I compare Gemini and Monet on my own venue?
Use a venue drawing where you know every dimension. Paste the same brief into both tools, send the same five follow-ups, then the same late change. Open every output in CAD over the drawing. Check scale, counts, aisles, exit paths and the files you can hand over.
