Common questions
- What do these guides cover?
- Eight guides written for buyers rather than for designers: what jewellery rendering is, what rendering and CAD design cost, what Etsy and Amazon require of listing images, the difference between STL and 3DM files, how to prepare a sketch for CAD, and video specifications for jewellery.
- What does jewellery CAD design and rendering cost?
- CAD design starts at $10 per design and 3D rendering at $20, with an Etsy Combo at $30 and animation from $50. The cost guides explain what moves those figures - stone count, pave and filigree work, extra angles, lifestyle scenes and revisions.
- Which file does my caster need, STL or 3DM?
- They are not interchangeable: one is a mesh and one is a surface file, and exporting the wrong way loses detail the caster needs. The STL vs 3DM guide sets out which one to send and what gets lost.
- What do Etsy and Amazon require of jewellery listing images?
- Each marketplace sets its own size, background and framing rules, and they are not the same. The Etsy and Amazon guides set out each one's current requirements separately.
- Do I need a CAD file before you can render anything?
- No. A sketch, a photograph or a reference image is enough - the CAD model is built first, from $10, and the renders come from that model.
