CAD to Product Rendering: What to Send Your 3D Studio

A useful product render starts with a handoff that explains both the object and the image you need. Sending a model is one part of that brief. Dimensions, finishes, variants and output requirements give the artist the information needed to turn geometry into a coherent set of marketing assets.

This guide is a practical checklist for a new project, whether your starting point is an engineering assembly or photographs of a physical sample.

Start with the source file and an agreed exchange format

Tell the studio which application and version created the design. Keep the native project available, and agree on an exchange format before exporting the whole range.

Autodesk's Fusion export documentation distinguishes formats such as STEP and STL. STL represents a surface through flat facets. Its mesh export guidance describes STL as unitless. These details matter when assessing curves and scale after import.

The practical recommendation is to send one representative product first. Ask the studio to confirm that the file opens, the required parts are present, and the size matches a known measurement. Export options vary between applications; a familiar extension alone does not prove a complete handoff.

Include dimensions and part names

State the unit system and provide at least one overall dimension that can be checked. A dimensioned drawing or a clearly marked reference image gives the artist a useful comparison.

Identify moving parts and components that need separate finishes. For a table, that might mean the base, top and hardware. For packaging, it could mean the cap, bottle, label and contents. Clear names are especially useful when the same model may later support animation or a configurator.

Explain which hidden details are required. An exploded animation needs different internal information from a front-facing catalog image. Let the intended shots guide that decision.

Describe finishes with references

Supply photographs or samples that show surface appearance, not only a color name. Record whether a finish should look brushed, polished, textured, translucent or coated. For labels and graphics, include the approved artwork and its intended placement.

A phone photograph can be useful context, but lighting and camera processing affect what it shows. Identify which reference is authoritative when several images disagree. Approve a material study before applying that finish across the whole image set.

Define variants before counting images

Create a list of products and available combinations. Distinguish a color change from a geometry change: a different handle, dimension or component may require more work than a new finish.

For example, three finishes across two product sizes does not automatically define the delivery. Specify which combinations need hero shots, detail views or animation. That turns an ambiguous request for “all variants” into a reviewable asset list.

Write the delivery brief around the destination

For each asset, state its use, aspect ratio, resolution, background and required file type. Include marketplace or website image requirements if they apply. For a film, define duration, frame rate and the versions needed for different screens.

For an interactive viewer, add target devices, option rules and required website integrations. Our WebGL configurator service explains those inputs in more detail.

Agree on who approves the work, what each review stage covers, and whether editable project files form part of the delivery. Keep one current set of comments so design changes and visual corrections can be tracked clearly.

A compact package to send

• Native design information and an agreed export.
• Units, a dimensioned reference and named parts.
• Finish references, labels and approved artwork.
• A product and variant list.
• A shot list or storyboard with final output requirements.
• A deadline, approval contact and agreed handoff expectations.
