How to Prepare Furniture References for 3D Modeling

What to send a CGI studio: clear dimensions, useful photographs, material references and a brief that leaves less room for guesswork.

A furniture model can only be as accurate as the information behind it. A folder full of photos won't help much if the chair in the pictures has different legs from the one being manufactured, or nobody knows which fabric is approved.

You don't need perfect CAD files to get started. Drawings, verified measurements and photos may be enough, provided the studio knows what represents the current design and what still needs confirmation. This guide covers visual and dimensional accuracy for CGI, not engineering approval.

1. Start with the correct product information

Begin with a short note identifying the product. Include its name, SKU or internal code, current design revision, measurement units and a contact who can answer questions. Say whether you're sending references for a finished product, a prototype or something still in development.

For example, “Lounge chair LC-21, revision R03, all dimensions in millimeters” is more useful than a folder called chair_final_new.

Identify the current drawings and photos. Older references may still be useful for a joint or seam, but label them clearly so they aren't mistaken for the approved design.

2. Check your drawings and measurements

Compare CAD files, drawings and specifications before sending. Check overall width, height and depth, then the details that define the shape: seat height, arm position, back angle, cushion thickness or leg profile.

If no technical drawing exists, measure the physical product and write the dimensions down. Photographs can show proportions and construction, but they are not a reliable substitute for actual measurements. On an upholstered chair, for instance, the frame drawing may define the size while photos help explain cushion volume and seam placement.

Suppose a drawing lists the chair's width as 820 mm, while the specification says 800 mm. Don't choose the number from the newest-looking file or split the difference. Ask whoever owns the product specification which measurement is correct and record the answer.

State the units and label any conversions between inches and millimeters. Include one verified dimension to check the imported model. Never treat a resized PDF or screenshot as a scale drawing.

What if some details aren't decided yet?

You can still share the references. Make a short list of open questions, such as:

Arm width: awaiting confirmation from product development.
Rear seam: visible on the prototype, but not yet approved for production.
Leg finish: supplier sample to follow.

An unknown arm width can hold up modeling; an undecided lifestyle prop usually won't. Product-defining details should be confirmed, not guessed.

3. Take clear photos from the important angles

Reference photos need clarity, not professional styling.

Start with these views of the same product version:

Front, back, left and right sides.
At least one three-quarter view.
Top, underside or open positions, if they matter to the product.
Close-ups of seams, piping, joints, cushion edges, handles, legs and visible hardware.

Use even light, keep the camera reasonably level and step back rather than shooting very close with an ultra-wide lens. Leave the whole item in the frame. Send original image files where possible; compressed screenshots can make small details harder to inspect.

Pair detail photos with wider shots that show their location, and give the files descriptive names. For asymmetric furniture, define left and right, and label each configuration.

If you're photographing a prototype, say what's temporary. A seam or leg shown in a prototype photo may be useful for understanding construction without being part of the final design.

No physical sample yet? Drawings and approved dimensions can still support CGI production, but provisional details need to be identified. Our article on Creating Product Visuals Before a Physical Prototype Exists explains that workflow.

4. Match materials to components and explain the variants

Sending a fabric photo and writing “oak legs” isn't quite enough. The artist also needs to know where each finish goes and what it should look like on the finished piece.

A simple annotated product image or table works well:

Component	Approved reference	Important detail
Seat and back	Fabric F01	Weave runs vertically on the back
Wooden legs	Oak finish F02	Grain follows the length of each leg
Leg caps	Black finish F03	Matte, not glossy

Include supplier codes, photograph samples in neutral light and show texture scale. For patterned fabric, specify repeat size and alignment; for wood or brushed metal, mark the direction.

Colors in photos can shift with lighting, camera processing and screen settings. A physical swatch is helpful when a precise match matters. Mood images are fine for showing an atmosphere, but label them as inspiration rather than approved material references.

Digital materials also reproduce surface texture and light response, as explained in Adobe's 3D texturing guide. Substance 3D Sampler can build material maps from photos, but the result must still be checked against the approved finish.

Don't treat every product option as a color change

A chair offered in blue and gray fabric may use the same 3D geometry. A wider chair, a different leg design or a modular sofa arrangement may need additional modeling. Even fabric and leather versions can have different seam layouts.

List each SKU or configuration and explain what changes: material only, dimensions, components or construction. For modular furniture, provide the assembled arrangement and its orientation, not just a list of modules.

5. List the deliverables and send one organized package

Before the studio starts, specify what you need from the finished model. For example: four product views on white, a close-up of the upholstery, an image with dimensions and one lifestyle scene. That's an example, not a default requirement for every project.

For each asset, list the SKU, view, finish, intended use and required format. Marketplace images and campaign renders often have different specifications.

If you also need a GLB model, animation, 360° view or editable source files, mention that separately. These aren't automatically included with still images. Interactive models may need additional preparation and optimization; the Khronos Asset Creation Guidelines are a useful technical reference for commerce-ready 3D assets.

If web-based 3D is part of the plan, see How GLB Models Are Used in E-commerce and Marketplaces.

Keep the handover simple

Put the approved drawings, photos, material references and deliverable list into clearly named folders. A structure such as LC-21_R03/drawings/, photos/, materials/ and brief/ is perfectly adequate. Make the current versions easy to find instead of expecting the artist to choose between files named “final” and “final_v2.”

Include a short note with the product revision, remaining questions and the person responsible for approvals. One person should collect feedback and send the studio a consistent set of decisions.

Test the files and sharing permissions. If a drawing, finish or product revision changes, send a clearly labelled update rather than silently replacing files.
