Convert OBJ to STEP with Holes Preserved
Upload your OBJ to Paramesh AI. The pipeline detects cylindrical holes automatically during feature recognition, then reconstructs them as proper parametric cuts in the STEP output. Through-holes and blind holes are both supported, with radius and depth extracted from the mesh geometry.
The OBJ to STEP challenge
OBJ files, like STL, are mesh formats with no feature intelligence. Converting to STEP naively gives you a faceted solid where holes are just arrangements of triangles — not actual cylindrical features you can edit.
Hole-preserving conversion
Paramesh AI's pipeline:
- Loads the OBJ and repairs any mesh issues
- Segments cylindrical regions from the mesh
- Fits exact cylinders (center, axis, radius) to each region
- Classifies as through-hole or blind-hole
- Builds the STEP solid with proper cylindrical cuts at each hole position
The result: a STEP file where holes are true cylinders you can resize, reposition, or delete in any CAD software.
