Plenty of parts start life as 3D models, not drawings. Nestpact now accepts STL, OBJ, PLY, and 3MF files directly: it detects the part's largest planar face, orients it flat, projects the outline, and the result nests exactly like a DXF part.
How it works
- The mesh's largest flat facet is detected and oriented to the cutting plane.
- Every triangle is projected and unioned into a clean 2D silhouette, holes included.
- Thickness is read from the model and shown on the part, in your working units.
- A 3D preview viewer shows the model so you can confirm the projected face is the right one.
Dense meshes are decimated automatically, and models above 200K triangles are rejected up front with a clear message instead of a hung browser tab.
