AI CAD for Measured Parts and STL or STEP Export
Partvo is an AI-assisted CAD studio for turning a description, reference images and measured dimensions into a digital design you can inspect and revise. For a simple replacement part, bring the dimensions that determine fit, then check the exact exported version in CAD or a slicer before making it. A photograph does not establish scale, and an exported file does not prove physical fit.
AI CAD or a CAD designer: which fits your replacement part?
| Your task | Suitable next step | What still needs checking |
|---|---|---|
| A simple, noncritical part with known dimensions | Try an AI-assisted measured brief, inspect the output and revise one dimension at a time. | Units, outside size, mating geometry and a prototype fit test. |
| A replacement with hidden or uncertain mating geometry | Measure the original and the object it fits. Use a CAD designer if you cannot establish the geometry needed for the repair. | Keep unknown dimensions explicit; a convincing render is not a measurement. |
| A complex assembly, safety-critical use or required engineering drawings | Work with a qualified CAD designer or engineer on constraints, drawings and use-specific review. | Loads, tolerances, material, manufacturing process and physical validation. |
Partvo can help draft a design; it does not replace professional approval where your use requires it. The replacement-part guide explains how to record measurements before generating a model.
Which format does your next step need?
| Format | Typical next step | What to verify |
|---|---|---|
| STL | Mesh-based slicing and 3D printing | Units, mesh integrity, dimensions, and print setup. |
| STEP | CAD inspection and further editing | Available for the validated version; check geometry and units. Original feature history may not be included. |
| DXF | Suitable flat cutting outlines | A validated outline for the design, sheet dimensions, fit, and separate CAM review. |
Download only the formats shown for the validated version. A successful digital export does not prove physical fit or manufacturing suitability.
Inspect real digital files before starting
The founder-owned mounting plate example includes STEP, STL, a recipe, and a validation report for a 90 × 50 × 5 mm plate. It comes from a local compiler integration pilot, not a live paid Studio run. Physical fit is untested.
For a suitable flat design with DXF output, inspect the two-panel plywood display example and its fit coupon. It has not been physically cut or approved for stability.
| Check | Recorded result | What it establishes |
|---|---|---|
| Units and outside dimensions | Millimetres; 90 × 50 × 5 mm | The exported version's measured bounding box. |
| Solid and mesh | One solid; watertight mesh | Digital geometry checks for this version. |
| STEP and STL round trips | Both passed | The exported files passed the recorded reopen checks. |
| Hole locations | Four template probes passed | Template-based feature inspection, not a physical measurement. |
| Physical fit and manufacturing | Fit not tested; freeform manufacture review not evaluated | A prototype and use-specific review are still required. |

This founder-owned example came from a local compiler integration pilot with a replayed hosted design call. It does not establish a live paid Studio run or a finished replacement made from a photograph.
Take a measured brief into the Studio
- Record the dimensions that determine fit. State units, outside size, hole spacing and mating surfaces. Mark missing values unknown. Use the design brief checklist.
- Inspect the example files. Open the mounting plate STEP or STL in your own CAD or slicer and compare it with the recipe and validation report. The published sample is free to download without an account.
- Bring your own brief to the Partvo Studio. Sign in and review your available design credits and spending limit before generating. A sample download does not add credits to your account.
- Check the exact saved version. Download only the formats shown for that version. Verify units and critical dimensions before fabrication. Request a specific revision if needed; generation and revisions use credits.
The recorded plate checks apply to that example only. Your hosted result needs its own inspection, and physical fit remains unproven until tested.

STL vs STEP: which file should you download?
Choose STL for mesh-based printing workflows or STEP for CAD editing. Learn how units, fit checks and export formats affect your Partvo design.

How do monthly CAD credits and unsuccessful attempts work?
The monthly plan includes 10 million design credits for $3 plus applicable tax in the first month, then renews at $10/month until canceled. Unused monthly credits expire at renewal; extra-use credits do not reset monthly. Usage varies by task and revision, and consumed AI usage is charged even when an attempt is unsuccessful. Review your spending limit before creating a model.
Compare the current plan and read the credit and refund policy. Available export formats depend on the validated model; a credit allowance does not guarantee a set number of finished parts.
