From CAD to Photoreal: What Files Your Visualization Studio Actually Needs

Every visualisation project starts the same way: a folder of files lands in our inbox, and its quality determines the next three weeks. A complete, well-organised brief can cut production time dramatically. A vague one — “the design is mostly resolved, plans attached (some outdated)” — guarantees delays, rework, and a quote padded for uncertainty.

Here is exactly what to send, in order of importance.

The essentials

Floor plans, elevations, and sections. The non-negotiable core. PDF is fine for quoting; DWG or equivalent CAD files are better for modelling. Make sure they are current — modelling from superseded plans is the most expensive mistake a client can make, because everything built on top of them has to be rebuilt.

A 3D model, if you have one. SketchUp, Revit, Rhino, 3ds Max — we work from whatever your practice models in. A clean model with grouped geometry and roughly correct scale saves days. A messy one with flipped faces and stray geometry costs nearly as much time as modelling from scratch, so do not apologise for sending plans instead; sometimes plans are faster.

Material intentions. A schedule, a specification excerpt, or even a page of reference photos with “like this” annotations. We do not need final product codes on day one, but we do need to know whether that wall is off-form concrete or painted render — the modelling and lighting decisions diverge early.

Site and context information. A site plan, a survey, or simply good photographs of the street and neighbouring buildings taken on a phone. For our residential work across Perth, Sydney, and California, honest context — the actual neighbours, the real slope of the land — is what separates a credible render from a pretty fiction.

The view list. Which views matter, and why. Mark them up on a plan, send reference angles, or describe them in words (“street view from the north-east corner at eye level”). Deciding views early is the highest-leverage briefing decision you will make.

The accelerators

Landscape intent. Even a rough planting concept prevents the generic-shrubbery look. Native species suggestions for Australian projects, for example, immediately ground the image.

Interior styling direction. For interior views — like our Nordhavn Museum interior series, where atmosphere carries the image — furniture style, art, and lighting intent matter enormously. A few reference images beat a paragraph of adjectives.

Lighting and mood references. One dusk, one overcast, one bright daylight? Tell us which views get which treatment. Renders are lit like photographs; art direction up front beats relighting later.

What the images are for. DA submission, competition board, client presentation, off-the-plan marketing — each implies different views, different honesty thresholds, and different licensing. Say it explicitly.

What slows projects down

Three patterns account for most delays we see:

1. Materials decided mid-render. Changing the cladding after the exterior is lit means rebuilding the image. Lock materials before visualisation starts, or brief explicitly that they are provisional.
2. Feedback by committee, unconsolidated. Five stakeholders emailing contradictory markups is how weeks disappear. Nominate one person to consolidate feedback into a single annotated round.
3. Scope creep on views. “Can we just add an aerial?” is never just an aerial. Treat each added view as a mini-project with its own time and cost — because it is.

None of this requires you to be a visualisation expert. It requires the files to be current, the views to be decided, and one person empowered to say “approved.” Send us that, and the photorealistic part is our problem.
