STL to Parametric CAD Conversion
Yes. Paramesh AI converts STL meshes into parametric CAD models with a full feature tree — sketches, extrusions, holes, chamfers, and fillets. The output is a clean B-rep solid built from scratch, not a wrapped mesh. You get an editable model with under 3% volume error compared to the original.
What is parametric CAD conversion?
Parametric conversion goes beyond simple mesh-to-solid wrapping. It reverse-engineers the original design intent: identifying that a circular region is a through-hole, that a flat surface is an extruded sketch, that a beveled edge is a chamfer. The result is a feature tree identical to what a human would create in Fusion 360 or SolidWorks.
What features does Paramesh AI detect?
- Base extrusion — the primary body shape from a 2D profile
- Through-holes — cylindrical cuts that pass completely through the part
- Blind holes — cylindrical cuts that stop partway
- Chamfers — beveled edges and countersinks
- Fillets — rounded edges
- Pockets and slots — recessed features
How accurate is it?
On tested models, Paramesh AI achieves under 3% volume error compared to the reference STEP file. The bounding box overlap is typically 99%+. Feature count matches within 1-2 features of the original.
