1. Corner Tool is in the tool bar

2. Corners without the corner tool in Affinity Designer

You can modify the corners using the move tool with some shapes such as rectangles as well as cog designs and stars and more. Go to the top of the application and the options and set the corner value as well as the corner type such as rounded and straight etc

3. Corner tool Radius Option

You can modify the corners using the corner tool. You can select one of the corners (click the little square box as the node and you will notice that the square is now filled) or multiple corners with the tool and change interactively the radius by dragging the small red dot near the corner. You can also change the radius via the slider in the options along the top of the application

You can set the value to a certain maximum value. The radius will not go beyond the maximum roundness of the path at that point. There is a limitation that if you select multiple nodes, the radius will stop when any of the radius settings matches the maximum. If you want to change another radius further you must de-select the one the blocks the others.

4. Corner tool and type such as straight, concave etc

By default there is no corner and it is set to none. Some paths will never have a corner such as a circle. The key thing is that there is a sharp point to begin with.

A range of types are available for the corner: none / rounded / straight / concave / cutout.

5. Resetting of corners

You can reset the corner back to the sharp point by double clicking the interactive red spot or filled square spot. You can then re-drag the intractive control outwards to the maximum value.

6. Freezing corner or 'bake appearance' of the corners

You can click the bake appearance button along the top of the options to lock / freeze or bake in the corners.


Once this has been done, you will probably (unless you still have some sharp points to change) be able to use the corner tool

You will see the result as tiny little dots around the entire path

You can then use the node tool to manipulate each of these nodes.

7. Modify multiple paths and corners using corner tool

You can create multiplle shapes with a variety of tools such as the star tool, trapezoid tool and so on and you can select all the shapes via layers panel. Select all the shapes with the cprner tool and you will see you have white squares representing all the sharp points / nodes. If you want to round them, drag over all the shapes and all the nodes will be filled and you can then use the corner tool to interactively change all the nodes, rounding all of the selected shapes
