Event CAD & 3D Modelling with Fly-throughs and VR Walkthroughs

Event CAD Drawings and 3D Modelling

I offer a complete drawings and visualisations for events, starting with a site visit where needed, through to CAD plans, 3D scale models and technical documentation packs.

Depending on the project, I can:

  • Carry out site visits / technical recces to capture constraints (access, rigging, power, sightlines, network and venue rules)
  • Produce CAD floorplans and production drawings for stakeholder sign-off and supplier coordination
  • Convert CAD layouts into 3D scale models to validate spacing and technical feasibility
  • Add audience seating to test sightlines, screen legibility and viewing angles
  • Preview creative assets such as branding, content placement, gobos and scenic elements within the model
  • Produce 3D fly-throughs for stakeholder review and internal alignment
  • Provide VR walkthroughs where useful for approvals and team briefings
  • Issue accurate, department-ready documentation including lighting plots, speaker plots, patch/cable calls, and other technical schedules as required

When’s it useful

  • Multi-room conferences and complex venue layouts
  • Stakeholder-heavy approvals (client, venue, production, safety, branding)
  • Builds where sightlines, screen placement, or audience experience is critical
  • Hybrid / streamed events where camera positions, backgrounds / screens and contributor confidence returns need planning
  • Immersive or branded environments where asset placement matters
  • Tender submissions where clear drawings strengthen delivery credibility

Outputs you can expect

2D drawings

  • General arrangement floorplans (audience, stage, FOH, back-of-house, access/egress)
  • Production layouts with staging, screen/projection positions, control points and backstage zones
  • Department overlays (lighting, audio, video, camera) when useful for clarity
  • Rigging intent drawings for coordination (not engineering sign-off)
  • Power / network intent diagrams where required to coordinate interfaces and routing

3D modelling and visualisation

  • 3D scale model of the space and event build
  • Audience seating in-model to test sightlines and viewing angles
  • Asset previews (branding, gobos, scenic, content positions) for stakeholder review
  • Still renders for sign-off and internal alignment
  • Fly-through videos where a walkthrough is the clearest way to communicate intent
  • VR walkthroughs where useful for approvals and team briefings

Department documentation

  • Lighting plots and patch lists (where required)
  • Speaker plots / mic schedules for sessions and stage formats
  • Cable calls / patch schedules and technical call sheets where appropriate
  • A controlled drawing set (versioning and notes), so everyone is working from the same reference

Site visits / technical recces

If the venue information is incomplete (or the event is sensitive to constraints), I can carry out a site visit and capture the details that tend to cause friction later:

  • Loading and access routes, lift sizes, working hours, storage areas
  • Rigging points and limitations, overhead restrictions and exclusions
  • Temporary power constraints and distribution considerations
  • Network availability, comms constraints and venue rules
  • Sightline issues, ambient light, screen viability and audience flow

The output from a site visit feeds directly into the CAD plan and the 3D model.

Tools and formats

I work across AutoCAD and WYSIWYG, and use Visio where a fast schematic is the right answer. Outputs can be supplied in common formats for suppliers and venues (PDF and native files where agreed), with a clean versioning approach.

If you already have drawing standards/templates, I can work to them. If not, I can supply a consistent drawing pack format.

Examples

Many projects are covered by client confidentiality, so I don’t publish full drawing packs publicly. If you’d like to see relevant examples, contact me with a short brief and I can share redacted samples privately.
