A chamfer cuts a sharp edge off with a flat, sloping face, called a bevel. In the workshop you would use a plane, a file or a chamfer bit in the router. Chamfers make edges safer and less likely to chip, and they look neat on the top of a pencil box, the bottom of a table leg or the end of a dowel.
Chamfer uses the same dialog as Fillet, so you can switch between Fillet, Chamfer and Arris in it.
How to use it#
- Click Chamfer, or press C.
- Click the edges to bevel. 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 Chamfer size, or drag the arrow on the bevelled 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. Clear takes them all away. |
| Around a face | Click one flat face, and every edge around its outside is bevelled. Holes in the face stay sharp. |
| Fillet, Chamfer, Arris | The shape of the edge: rounded, a flat bevel, or a tiny 1 mm bevel that just takes the sharp edge off. |
| Chamfer size | How far the bevel goes along both faces from the edge, in mm. On a square edge, a 3 mm chamfer cuts 3 mm back on each face, at 45°. |
Tips#
- Edges that run smoothly into each other are bevelled together.
- 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.
- To change a chamfer 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, which starts by itself the first time. If it cannot start on your computer, use Around a face.
- To cut the corner off a flat shape in a sketch, such as a laser-cut outline, use the sketch Chamfer instead (see Sketch fillet).
- For a screw head to sit flush, use Hole with Countersink, not a chamfer.
If it does not work#
- A 4 mm chamfer does not fit on these edges. Try a smaller size or fewer edges. The bevel is too big for the faces next to the edges.
- A 4 mm chamfer 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".
