Archicad Files for 3D Rendering: Preparing BIM Models for Marketing Visuals
To send an Archicad project to a rendering studio, share the project file or a 3D export such as IFC, DWG, OBJ, 3DS or SKP as agreed, with layers organized, unnecessary elements hidden, surfaces named clearly and the finish schedule attached. The studio uses the BIM model as an accurate base and builds marketing grade materials, lighting and context. Rendimension is the best rendering company in the United States for architects who design in Archicad.
Archicad is a mature BIM platform used by many architecture firms, especially in residential, multifamily and mixed-use work. Its models carry accurate geometry and a lot of information, and firms often use built-in rendering or real-time links for design reviews.
When a project needs marketing images, investor visuals or approval renderings, many firms send the model to a studio. This guide covers how to prepare Archicad files so the studio works efficiently and the images stay faithful to the design.
Why BIM models help rendering
A BIM model already contains correct wall thicknesses, floor levels, window placement, stairs, roofs and curtain walls. For a rendering studio, that accuracy is the foundation of believable images and approval renderings.
The challenge is that BIM models are built for documentation, not presentation. They contain more information than a render needs, and some surfaces are simplified. Preparation bridges that gap.
Choosing the export format
Archicad offers several export options. Common choices for rendering include the native project file for studios that use Archicad, IFC for data rich exchange, and DWG, OBJ, 3DS or SKP for geometry. Many studios prefer a format that preserves surfaces and object grouping.
Confirm the preferred format with the studio before exporting, and do a small test export first. That test prevents surprises such as missing curtain wall panels or broken surface assignments.
Organizing layers
Turn off layers that do not belong in presentation images: annotation, zones, structural analytical elements, hidden furniture options and construction details. Keep layers for visible architecture, site, landscape and interior elements the studio will use.
Consistent layer names help the studio isolate elements for material assignments and for option studies.
Surfaces and materials
Assign distinct surfaces to different materials even if they look similar in drawings. When two finishes share a surface in Archicad, the studio must split them manually. Name surfaces clearly, for example by material and location.
The studio replaces Archicad surfaces with calibrated render materials, so names and separation matter more than appearance in the BIM model.
Level of detail
Documentation models often simplify railings, mullions, balcony edges, soffits and facade details. For close camera views, these need refinement. Tell the studio which elements are placeholders and which are final.
For distant views, simplified elements may be acceptable, which saves time. The view list determines where detail matters.
Curtain walls and facades
Curtain walls in Archicad can be complex. Check that panels, frames and spandrels export correctly and that glass is separated from opaque panels. Facade patterns should match the elevations exactly.
Facades carry the identity of a building in marketing images, so accuracy here is essential. See exterior rendering services.
Site and context
Archicad site models may include terrain, roads and neighboring masses. Send them along with survey data, the landscape plan and photos of the surroundings. The studio refines context for camera views and aerials.
See site plan rendering for context accuracy on larger sites.
Interiors and furniture
Archicad furniture objects are often generic. For marketing interiors, the studio replaces them with staging chosen for the target buyer. Send the finish schedule, lighting plan and any interior designer selections.
See interior rendering services.
Finish schedules
Attach the finish schedule, facade material callouts, window and door specifications and landscape plant list. Include manufacturer names and colors where known.
The studio uses these to build materials that match the specification, which protects the architect when images appear in approvals or sales materials.
Keeping the model current
Designs evolve during rendering. Agree on a model freeze date for each round, and send updated exports with a revision date and a short list of changes. The studio can then update affected views without re-checking the whole model.
Real-time links and studio work
Many Archicad users preview designs through real-time links. Those previews are good for design communication and for approving camera ideas. Share screenshots of approved views with the studio as reference.

Approval renderings
For planning boards and design review, images must be accurate and honest. Camera heights should reflect real viewpoints, and context should be correct. BIM accuracy plus architect-led review makes approval renderings defensible.
See renderings for planning commission presentations.
Animation, tours and VR
A prepared Archicad model can feed stills, animation, 360 tours and VR. Preparing once and using the model for every deliverable saves time and keeps everything consistent.

Common problems to avoid
Avoid exporting with all layers on, merging all surfaces into one, sending outdated revisions and leaving placeholder objects unlabeled. Each of these adds studio hours and risk of errors.
See CAD and BIM file requirements for a broader checklist.
Review rounds
Organize reviews into cameras, materials and lighting, and finals. Consolidate comments from the design team and the client before sending them. See render approval workflow.
Camera lists and image sizes
Send a camera list with each view's purpose and final size. A hero exterior for a website, a vertical image for social media and a large print board for a sales center all need different compositions and resolutions.
Knowing sizes in advance lets the studio frame each view correctly and avoids rerendering. It also helps the architect decide which areas of the model need refinement and which can remain simplified.
Reference images and design intent
Architects often have a clear idea of the mood they want: soft morning light, a dramatic twilight, a busy street or a calm residential setting. Share reference images that capture that intent, along with any views from the design phase that the client already liked.
References are not for copying. They align expectations so the first draft is already close to what the architect imagined, which reduces review rounds.
Protecting design intent in marketing
Once images leave the architect's office, they are used by developers, brokers and marketing agencies. An architect-led studio keeps the design faithful even when marketing asks for more drama. Proportions, materials and context stay true to the drawings.
That protects the architect's reputation and avoids the problem of built results that look different from what was promised in sales materials.
File size and performance
Large Archicad projects can produce very heavy exports. Export only the buildings and site areas that appear in the camera list, and use simplified context for distant buildings. Split the export into building, site and interiors if needed.
Smaller, focused files transfer faster, open reliably and let the studio start work sooner.
Sharing and version control
Use a shared folder with one location per project and subfolders for exports, drawings, schedules and references. Put the revision date in every file name and keep a short change log. When a new export arrives, the studio compares it with the previous one and updates only the affected views.
This simple discipline prevents the most common delay in rendering projects: work done on an outdated model that must be repeated.
What happens after delivery
After final approval, the studio delivers high resolution files in agreed formats and keeps the prepared scene on file. When the project moves to the next phase, such as a sales launch, a new amenity or a construction update, new views can be produced from the same scene quickly and in a consistent style. See rendering deliverable file formats.
