How do I check a floor plan for capacity and aisle problems?

A plan can look beautiful and still be unbuildable. Diagram Check holds a layout against standards you set, and points at the specific items that break them.

Set your standards once — minimum aisle, square feet per seat, fire-code capacity — and every diagram gets held to them.

Running it

1. Open Diagram Check — the last icon on the left rail.
2. Set Minimum aisle between tables to your house standard.
3. Set Minimum ft² per seat — the number that decides whether a space feels generous or packed.
4. Add a maximum capacity if the space has a fire-code limit you must not exceed.
5. Click Run check.

Findings are clickable. Click one and it selects the offending items on the canvas, so you are not hunting for which two tables are too close together.

What it catches

Tables closer than your aisle standard. A seat count too dense for the square footage. A layout over a hard capacity limit. And anything that has drifted outside the walls of the event space — the error that is invisible on a zoomed-in screen and obvious at load-in.

Reasonable starting numbers

These vary by market and by what you are selling, so treat them as a starting point rather than gospel: banquet seating is commonly planned around 12–15 ft² per seat, with aisles wide enough for a server to pass behind a seated guest. Set what your operation actually uses and let the check enforce it consistently.
