How NitoCAD verifies AI-generated CAD designs
NitoCAD does not treat a generated model as correct. It checks each version against your requirements and answers PASS, FAIL or UNKNOWN. UNKNOWN is never shown as a pass.
| Result | Meaning |
|---|---|
| PASS | The check ran and the part meets the stated requirement. |
| FAIL | The check ran and the part does not meet the stated requirement. |
| UNKNOWN | NitoCAD could not measure it, or an input was missing. It is never reported as a pass. |
An example
These rows show how a bracket might be reported. They are an illustration, not a saved result.
| Requirement | You said | Measured | Result |
|---|---|---|---|
| Envelope | Fits in 100 x 80 x 60 mm | 96 x 62 x 40 mm | PASS |
| Mass | Under 200 g | 212 g | FAIL |
| Wall | At least 2 mm | 3 mm | PASS |
| Material | 6061 aluminium | not stated | UNKNOWN |
What gets checked
- The solid is valid. NitoCAD checks the geometry before anything else.
- Your requirements. They stay attached to the part and are checked again on every version, so an edit that quietly breaks an earlier requirement is caught when it is built, not when the part arrives.
- Manufacturability. Guideline checks for CNC machining, sheet metal, molding and 3D printing.
- Assemblies. Overlap and mass checks across the parts.
Where the checks stop
Geometric validity does not prove a part is safe, manufacturable or fit for its purpose.
Checks use typical shop guidelines, not your shop's limits. Aerospace results stop at "ready for engineering review". Civil checks are screening level and building rules are conceptual. A licensed engineer must verify anything that gets built. NitoCAD also keeps your numbers: if it sees a problem with a dimension, it flags it and leaves the value alone.
If a generation fails, you are not charged for it.
