Upload a photo of furniture, decor, or any custom rental piece and generate a usable 3D model in seconds or minutes. Save it directly to your catalog and use it in any event layout — whether you start with a basic starter library or a full extensive inventory. Build out stock and one-off custom items on your own timeline, without waiting weeks or paying premium rates for outsourced 3D modeling.
Rental companies, event designers, decorators, venues, and production teams who need to grow their catalog quickly — adding real inventory and custom pieces without hiring a 3D studio for every new SKU.
Event Design App™ combines AI 3D model generation with practical photo to 3D model workflows for the event rental industry. Build a rental inventory catalog with custom 3D assets in minutes, then use them in event visualization software and full 3D event design layouts — without outsourced 3D modeling costs or multi-week turnaround times.
Flagship Feature
Configure frame tents, pole tents, sailcloth, high-peak marquees, and more — attach sidewalls, hide the vinyl to layout the interior, and dress the space with pipe and drape, hanging drapes, ceiling drapes, and backdrops for a complete tent design. Every size you need, or we create the type and dimensions for you.
Multiple sizes for every style. Need something not in the library? New tent types and custom dimensions can be created for your fleet.
Attach sidewalls to any side of the tent. Mix wall styles per panel — open one face, glass on another, solid on the rest.
Event Design App™ is professional tent design software and an event tent builder for rental companies and planners — configure frame tent layouts, pole tent designs, sailcloth and marquee tents with sidewall options, then visualize the full interior in 3D tent layout software before install day.
Start with real-scale tents, sidewalls, interiors, and inventory in one browser-based workspace.
New & Unique
Upload photos of a real room, tent, backyard, or ballroom and generate a 3D model of the space itself. It is stored, so you can open that venue again anytime — no need to generate it twice. Then design the event inside it: add inventory, furniture, staging, and more models, instead of starting from a blank grid or waiting on a CAD rebuild.
Start with photos of the actual space. AI builds a 3D venue model you can walk, measure, and design inside — not a flat backdrop or a generic room template.
Drop in tables, chairs, tents, staging, draping, and the rest of your inventory. The venue is the workspace, so the layout is planned against the real room, not an empty canvas.
The venue is stored after it is generated. Open it again for the next event, quote, or revision — you do not generate it again. Add more models, refine the layout, and present a design the client can actually see in their own space.
This is different from turning a product photo into inventory, and different from scaling a floor-plan image. Event Design App™ generates the venue itself from photos as a usable 3D model, then lets you design the event inside it — a workflow we have not seen anywhere else in event design software.
Upload a venue floor plan image, measure just one wall, and AI generates a full building setup at true scale — then start designing inside it immediately. Drop in your rental inventory and furniture, refine the layout, and move from client floor plan to a polished event concept in a fraction of the time — without rebuilding the venue from scratch or waiting on manual 3D modeling.
Rental companies, venues, wedding planners, corporate event teams, and banquet operators who regularly receive floor plans from clients and need to turn them into actionable layouts with real inventory — quickly and without a CAD team.
Event Design App™ is event floor plan software built for rental workflows — an AI floor plan generator that turns an uploaded plan into a true-to-scale 3D venue layout from a single wall measurement. Use it as venue layout software and event space planning software to place rental inventory in context, create accurate banquet and wedding floor plans, and deliver event layout designs faster than traditional floor plan to 3D modeling alone.
Stack Stage Builder
Configure a build stack stage inside your event layout — set overall size, deck height, stair placement, skirts, and railings in true scale. Event Design App generates how many of each piece you need to build it, and flags safety requirements when height calls for railing.
Purpose-built stack stage builder and modular stage design software for rental and production teams who need more than a generic platform block — design, visualize, and count parts in one workflow.
Stage size
Overall footprint
Deck height
Stack elevation
Stairs

Skirts

Height-based alerts
See exactly how many decks, legs, stairs, skirts, and rail pieces your stage requires — generated from your design, not guessed from a spreadsheet.
When deck height exceeds safe thresholds, the builder recommends railing where it is required — so your layout reflects real-world staging standards before load-in.
Ideal for rental companies, AV and production crews, corporate events, concerts, schools, and houses of worship planning portable stage layouts, event staging designs, and stack stage configurations with accurate stage bill of materials output — the kind of 3D stage design software teams search for when generic floor plan tools cannot model real modular staging.
Create realistic pipe-and-drape layouts, ceiling drapes, wall draping, backdrops, and fabric installations using our procedural curtain tool. Simply drag the control points to shape the fabric, adjust the dimensions, folds, curve, material, transparency, and color, then position it anywhere in your venue or tent. No 3D modeling experience required.
Wedding planners, event designers, rental companies, decorators, venues, production companies, trade shows, galas, corporate events, and anyone creating custom draping concepts.
Event Design App™ is purpose-built event draping software and pipe and drape design software for professionals who need a fast wedding draping designer, ceiling draping visualizer, and fabric backdrop designer in one browser-based platform. From first layout to client-ready visuals, it combines event rendering software, venue visualization software, and full 3D event design software so you can plan, present, and quote custom fabric installations without leaving the app.
