3D modeling: a guide for pros
What customers ask, how to win the job, and what to put on your profile.
Offering 3d modeling
You build digital three dimensional models and scenes for products, architecture, games and printing, and deliver files with textures and renders. Your value is accurate models that meet the client's dimensions and the format their process needs.
What customers ask
- Can you build the model from my drawings?
- Will the model print correctly on my printer?
- What file formats will I get?
- How long will the renders take?
- Can you match the colors and materials of my real product?
How to win the job
- On the first call, ask for the purpose of the model, the reference drawings or photos, the units, the tolerances, the file format and the deadline, then confirm them in writing.
- Confirm the units and the scale before modeling, and write them on the first preview image.
- Send a wireframe or a clay style preview for approval before adding textures and lighting.
- Check the model for errors such as open edges or thin walls against the client's manufacturing rules, and report the findings.
- Deliver native source files and an exchange format, with a list of the textures and their sources.
- Keep a version history of the model, so the client can see what changed between revisions.
What to put on your profile
- Post renders and model views grouped by use, such as products, interiors or printed parts, with client permission.
- List the software and file formats you work in.
- Describe your review and error check steps in plain terms.
Follow-up that helps the customer
- Offer updated renders when the product design changes.
- Suggest a library of reusable components for the client's next product line.
- Recommend a test print or a prototype before a full production run.
Licenses and permits
3D modeling is usually not licensed. Keep your business registration current, and check your state or local rules for any registration your work requires; keep records of the licenses for every texture, model library and font you use.
Questions
Do I need a license to make 3D models?
Usually not. Check your state or local rules if you operate as a registered business, and confirm the rights to any library assets you use.
What if a client wants a model of a product they do not own?
Ask for written proof of the rights to the design, and decline the work if the client cannot show that they may use it.
How do I handle a client who sends changing measurements?
Confirm each change in writing with the units and the new measurement, and note how the change affects the schedule.
