The Short Answer

Event diagramming software draws a scaled diagram of an event space: walls, doors, booths, tables, zones, walking paths and labels laid over the venue drawing, so a team can plan the layout and share it. Map D's map editor builds that event diagram to scale from an image or a blank canvas, then publishes it as the live floor plan exhibitors and attendees use.

What Event Diagramming Software Does

Before anything is sold or signposted, someone has to work out what fits in the room. Event diagramming software is where that happens: the hall drawn to scale, the fixed things marked first (walls, doors, columns, exits), then zones, aisles, booths and tables placed around them. A good event diagram answers practical questions early. Do the aisles clear? Where does registration go? How many booths fit before the food court?

Map D's map editor is built for that planning stage and for what comes after it. The diagram you draw becomes the published floor plan. If you are mainly after the live, shareable result, see event floor plan software; for a quick start from a venue drawing, see the event floor plan maker. This page is about drawing the layout itself.

  1. The fixed structure: outer walls, doors, columns, loading docks and emergency exits
  2. Zones that need a set footprint, such as registration, a stage, seating or a food court
  3. Main aisles and walking routes, sized to your venue's and fire marshal's requirements
  4. Booths and tables, placed into what is left
  5. Labels and icons for restrooms, entrances, first aid and information desks

Drawing in that order keeps the event layout honest. Booths placed before the exits and aisles are fixed tend to be moved, renumbered and resold later.

Start From the Venue Drawing and Set the Scale

  1. 1

    Start From an Image or a Blank Map

    Import the venue's floor plan as a PNG or JPG, ideally 4000 x 3000 pixels or larger and up to 50 MB, and trace over it. Or enter the width and height of the floor and draw from scratch.

  2. 2

    Calibrate the Scale

    Select Calibrate, click two points whose real distance you know, such as the ends of a wall, and type that distance. Everything rescales to match. Then lock the map scale so it is not changed by accident.

  3. 3

    Set Units and References

    In Map Settings choose imperial or metric units, grid spacing, rulers, and whether booths show their dimensions and exhibitor names. Upload a booth layout reference to trace over that never appears on the published map.

  4. 4

    Add Context Around the Map

    Add a canvas background, such as an aerial photo of an outdoor site, behind the area outside the map boundary.

Drawing Tools for an Event Layout

Map editor tools for drawing an event layout
GroupToolsUse them for
StructureWall, DoorChains of wall points and single, double or open-passage doors
PathsPath, ConnectorWalking routes for wayfinding, and stairs, elevators or escalators between floors
AreasRectangle, Multi-pointZones such as a food court, stage or registration
Booths and tablesBooth, Layout, TableSingle booths, generated booth layouts and tables
Shapes and iconsRectangle, Circle, Polygon, Line, Arrow, Icon, MediaRestrooms, exits, your own images and logos
Annotate and fixText, Booth numbering, CleanupLabels, numbering in order, and painting over marks on the venue image

Every tool has a keyboard shortcut, a tool stays armed so the next click places another, and you can type an exact length while drawing. Layers let you hide, dim or lock the floor plan image, structure, booths, icons, text and paths, so you can work on one without disturbing the others.

Booths, Tables and Faster Layouts

Placing booths one by one is slow on a large floor. Drag a box with the Layout tool and choose an arrangement: single row, back to back, island or perimeter. Set the booth type, width, depth and aisle width, then fill the region or place up to a count. The preview updates as you change settings, and nothing is saved until you accept. Our trade show booth layout guide covers which arrangement suits which floor.

  • Number booths in the order you click, with a start number, a step, and text before or after such as A-
  • Use round booths with up to 16 chairs drawn around them for table-based layouts
  • Split one booth into a grid of smaller ones, or merge 2 to 8 side-by-side booths into one
  • Align and distribute several booths at once, or change their type, size and rotation together
  • Ask the floor plan assistant to align, distribute or rename in plain language, then review Proposed changes before applying

Check and Share the Event Diagram

The editor saves automatically to a draft, and visitors keep seeing the last published version until you publish. Before publishing, Map D checks the diagram and lists anything worth a look, such as booths that share a number, booths stacked on the same floor space, doors too wide for their wall, paths that cross a wall without a door, and booths that can't reach the walking paths. None of them stop you publishing.

Name the areas, icons and connectors you draw. Named places are what attendees can search in Find a place on the published plan, while words that are only part of the venue image are not searchable. See event wayfinding software for how paths become directions.

Draw Free, Publish When You Are Ready

A free Map D account gives you the map editor for one show. You can draw booths, areas, walls, paths and labels, number booths, set the scale, add a background image, save your work and export your map as an image with a Map D watermark. Start at free interactive floor plan.

Publishing the floor plan, watermark-free exports, booth sales, exhibitor portals, Homebase and the mobile app need a paid plan. Published plans start at $1,500 per event; see pricing. Everything you drew on the free account is still there when you upgrade.

How Map D Helps

How Map D Turns a Diagram Into a Live Floor Plan

The diagram you draw in Map D is not a separate file to keep in sync. Once published, the same map drives your booth registration page, Homebase floor plan, website embed and mobile app, so a change in the editor reaches every one of them.

  • Import a venue image or start from a blank map, then calibrate the scale
  • Walls, doors, paths, areas, booths, tables, icons and text on separate layers
  • Booth layout generator for rows, back-to-back, islands and perimeters
  • Click-to-number booths with prefixes and leading zeros
  • Pre-publish checks and a version history you can restore from
  • Floor plan assistant that proposes changes for you to review
See it on your own floor plan

Stop reading about it. Build one.

Upload the floor plan you already have and place your booths on it yourself, in Map D’s editor. Free to build, no contract, and nothing to install.

Frequently Asked Questions

Questions Organizers Ask

Can I make an event diagram for free?

Yes. A free Map D account gives you the map editor for one show: draw, number booths, set the scale, add a background image and export an image with a Map D watermark. Publishing the diagram needs a paid plan.

How do I draw an event layout to scale from the venue's floor plan?

Upload an image of the venue floor plan (PNG or JPG work best), then calibrate the scale by clicking two points whose real distance you know, such as the ends of a wall.

Can several people work on the same event layout?

One person edits at a time. Colleagues can pan, zoom, inspect and export while they wait, and editing is released after 15 minutes of inactivity so someone else can take over.

Does the event layout planner support metric units?

Yes. Map Settings lets you choose imperial or metric units, along with grid spacing, rulers and whether booths show their dimensions.
