A fillet rounds off an edge. In the workshop you would do it with a router and a round-over bit, a plane, a file or sandpaper. Rounded edges feel nicer in the hand, look finished, and are less likely to chip or splinter: think of the top of a step stool, the rails of a surf handplane, or the front edge of a phone stand.
The same dialog also makes a chamfer (a flat bevel) or an arris (a tiny bevel that just takes the sharp edge off).
How to use it#
- Click Fillet, or press R.
- Click the edges to round. An edge lights up orange when the pointer is on it. Click a flat face to pick all of its edges at once. Click an edge or a face again to take it away.
- Type the Radius, or drag the arrow on the rounded edge.
- Check the preview, then click ✓ or press Enter.
Options#
| Option | What it does |
|---|---|
| Edges | Pick edges one by one, or click a flat face for all of its edges, holes too. Clear takes them all away. |
| Around a face | Click one flat face, and every edge around its outside is rounded, like running a router round it. Holes in the face stay sharp. |
| Fillet | A rounded edge (in timber: a round-over). |
| Chamfer | A flat bevel. See Chamfer. |
| Arris | A tiny 1 mm bevel that just takes the sharp edge off. It has no size to set. |
| Radius | How big the round is, in mm. |
Tips#
- Edges that run smoothly into each other are rounded together, so one click can go all the way along a curved outline.
- On an inside corner, a fillet adds material instead of taking it away.
- When you drag the arrow, the steps get smaller as you zoom in. Hold Shift for finer steps, or press Esc to put the size back.
- Picked edges are found again when earlier features change size. To change a fillet later, double-click it in the feature tree, or click it once in the tree and drag its arrow on the model.
- Edges needs the 3D engine. It starts by itself the first time, which takes a few seconds. If it cannot start on your computer, use Around a face.
- Use Arris where a timber plan says to take the sharp edges off.
If it does not work#
- A 6 mm fillet does not fit on this edge. Try a smaller size or fewer edges. The round is too big for the faces next to the edge.
- A 6 mm round-over is too big for this shape. Try a smaller size. The same problem with Around a face.
- Click the edges to round (or a flat face to pick all of its edges). No edges are picked yet.
- The 3D engine is not available here, so edges cannot be picked. Choose "Around a face".
- 2 edges were not found after an earlier change. Edit the fillet to pick them again. In the dialog they show as red dashed lines where they were. Click the edges to use now, then click Remove to drop the old ones.
