Most tools add seating charts, collaboration and export to PDF so stakeholders can sign off before setup. Event-specific tools such as Social Tables and Prismm add venue libraries, guest management and 3D views.",{"question":304,"answer":305},"What is the best free event layout software?","Event Floor Planner describes itself as free with no signup, which suits weddings, parties and small banquets. Social Tables, OnePlan and Lucidchart all offer free tiers with usage limits, which are useful for trying them out before committing. Check each vendor's current limits, as free tiers change often.",{"question":307,"answer":308},"Which tool is best for seating charts and floor plans together?","Social Tables (Cvent Event Diagramming) and Prismm both combine to-scale layouts with seating charts and guest management. For a single free event, Event Floor Planner and SmartDraw's seating chart maker are lighter options. General diagramming tools like Visio and Lucidchart can draw seating, but they don't manage guests.",{"question":310,"answer":311},"Can I use AutoCAD or Visio for event diagrams?","Yes. AutoCAD is the standard for precise venue and technical drawings, and Visio's floor plan stencils work well for quick layouts in Microsoft 365 organizations. The trade-off is that neither has event-specific features like guest lists, venue libraries or attendee-facing maps. Every change also means re-exporting a static file.",{"question":313,"answer":314},"Is ExpoFP an event diagramming tool?","Not in the classic sense. ExpoFP doesn't do banquet seating, guest lists or meal management. It turns a floor plan into a live, interactive map where exhibitors reserve and buy booths and attendees search exhibitors and navigate in the browser. Many organizers use a diagramming or CAD tool to produce the layout, then upload it to ExpoFP to publish the exhibit floor.",{"question":316,"answer":317},"How much does event diagramming software cost?","It ranges from free (Event Floor Planner, and free tiers of Social Tables, OnePlan and Lucidchart) to about $5–$15\u002Fuser\u002Fmo for Visio and $49–$320\u002Fmo for Social Tables planner plans. AutoCAD is commonly listed at around $1,800–$2,000\u002Fyear per user in the US, and 3D and venue deployments such as Prismm's are often quote-based. For interactive exhibitor maps, ExpoFP's DIY plan is {diyPrice}\u002Fmo, and team-built plans start at {lightPrice} one-time.",{"heading":319,"items":320},"Related pages",[259,321,322,323,324,325,326,327],"[ExpoFP alternatives](expofp-alternatives)","[ExpoFP pricing](pricing)","[Exhibition floor plan software](exhibition-floor-plan-software)","[Convention center floor plans](convention-center-floor-plans)","[Best trade show floor plan software](best-trade-show-floor-plan-software)","[Best free event floor plan software](best-free-event-floor-plan-software)","[Best interactive event map software](best-interactive-event-map-software)","Information on this page is based on publicly available product materials as of {lastVerified} and may change.
