CAD preparation checklist for product animation

1. Define one question the visual should answer

Write down who will watch or use the result, where it will appear and what that person should understand afterward. “Show how the internal valve opens” gives the project a clearer direction than “make it look impressive.”

Choose the most useful first deliverable: a product animation, a set of presentation slides or an interactive demonstration. If you need more than one, identify what information and geometry they can share.

2. Describe the files you already have

Note whether you have a native CAD assembly, an exported 3D model, drawings, photos or dimensions. Include the file format, approximate file size and whether the assembly has separately named parts. Compatibility is reviewed before production; having a model does not automatically make it animation-ready.

Do not remove engineering information from your only working copy. Keep the original unchanged and agree on any simplified visual version. If you have no 3D model, photos, drawings and useful dimensions can provide a starting point for a scoped model.

3. Identify the parts and movement that matter

List the components the audience needs to see, which ones move, and how they relate. Label hidden parts that should be revealed in a cutaway or exploded view. Describe the motion limits, sequence and intended end positions rather than expecting the model alone to explain them.

For a planning estimate, count distinct component designs, including stationary parts that need preparation. Repeated identical components count once. Simple or detailed standard projects with more than 15 distinct components need a custom scope review.

• Name the component or assembly.
• Describe what changes and in what order.
• Identify the approved reference for that behavior.
• Flag anything that must remain hidden or be simplified.

4. Gather appearance and output references

Product photos can clarify materials, surface finish, colors and markings that may not be present in CAD. Identify the current product revision and supply approved labels and branding when an appropriate sharing method has been arranged.

List the intended uses: product page, sales deck, social video or trade-show screen. For an interactive demo, describe the controls people need and the devices they will use. Hardware, installation, offline operation and ongoing hosting need separate agreement.

5. Name the technical reviewer and approval steps

Decide who can confirm the geometry, labels and behavior. A visual explanation can simplify a mechanism for clarity, but it does not certify an engineering design or replace performance testing.

Consolidate feedback at the agreed milestones. Confirm final deliverables, editable assets, source-file handover and usage rights in the written proposal. These are not automatically granted by a planning estimate.

6. Start with a non-confidential description

The quote form is a place to describe your project, not to upload confidential design files. Share a public product link, your goal, the available file types and the scope you have in mind. An appropriate process for sharing confidential assets can then be agreed.

A useful first message is: “We need to explain [feature] to [audience] for [use]. We have [file types and references]. The sequence should show [steps]. Our target date is [date or flexible], and [person or role] will review technical accuracy.”
