3D finish (beta)
Finishes the model after roughing: parallel passes, waterline round steep walls, steep & shallow, the flat floors, or pencil along inside corners.
Use it for: Finishing mould cavities, cores and 3D parts.
Tool: A ball nose (or a bull nose / flat end mill on gentle shapes).
Settings
| Setting | What it does | Default |
|---|---|---|
| Strategy | Parallel (gentle surfaces), Waterline (steep walls, at constant heights), Steep & shallow (waterline above the angle, parallel below), Flat areas (floors, rings inward), Pencil (inside corners and fillets tighter than the tool; corners turning over 15°, i.e. 165° bitangency), Rest (only what a larger tool used before could not reach), Scallop (passes the same distance apart over the surface everywhere), Spiral and Radial (out from the middle, for round cavities and cores), Morphed spiral (one continuous pass following the boundary inward). Pencil takes passes beside it (parallel pencil). | Parallel |
| Slope from / to | Contact angle range for parallel and waterline: only where the surface is that steep. | 0–90° |
| Stepover | Distance between passes; with a ball nose the ridges left are about stepover² / (8 × radius) high. | from the tool (≈ 0.005 mm ridges) |
| Angle | Direction of the passes. | 45° |
| Tolerance | How far the straight moves between points may stray from the surface. | 0.01 mm |
| Boundary | Model outline (the tool rolls a radius past it), whole stock, or selected shapes; Extend. | Model outline |

Tips
- A typical mould: 3D rough, rest roughing with a smaller tool, steep & shallow with a ball nose, flat areas with a flat end mill, rest with a smaller ball, pencil last.
- Into-the-model is measured square to the surface; the checks replay the stock the operations before left.
