Round a single angle of a rectange ?

Hi,

 

How to round a single angle of a rectangle ?

 

Thank

In Affinity Designer Desktop:

under the node took you can click on corner tool or use shortcut “c” which allows u to make adjustments to your vector corner at ease. 

In Affinity Photo its a bit more complicated since its more for photo and bitmap minupilation purposes, doesnt have as many vector tools as designer so vector shape minupilations require some extra steps.

In Affinity Photo Desktop:

turn on snapping to vector shapes, create a circle, resize and position it where you want to make the curve and use the boelean operations to attach the rounded corner to your shape  

In Affinity Photo iPad 

try to use the desktop method or - place a plastic coin you ipad where you want to make the curve and erase the extra edge with eraser or - get a desktop while we all wait for affinity designer for ipad and affinity publisher to come out , supposebly this summer... which is been taking forever now. Although i must say all those refreshes on affinity forum may have made it feel much longer that it should...

I’m not too familiar with the iPad version, so may be missing something buT you can use Boolean operations

Create a rectangle and duplicate it. Draw a circle on top in one corner that very slightly overlaps the rectangle. It must overlap the edges or the Boolean operation won’t work.

Select the circle and the top rectangle, in Geometry, choose Divide, which will leave you with several odd shapes.

In the layers studio, delete everything except the original rectangle and the bit that looks like a triangle with a concave inner, basically the opposite of a rounded corner. You will use that to cut the corner off. Select both objects and in geometry, choose subtract.

The triangle bit will chop the corner off, leaving you with one rounded corner.

It is a lot easier to do than it is to describe.

That almost works, but when I tried it just now I got a sharp transition between the circular arc and the straight sides of the rectangle. I think it’s easier to get reliable results if you start with a round-cornered rectangle and Boolean ‘add’ squares to the other three corners to straighten them out.

Yes, it was a bit tricky on an iPad with fat fingers. I must admit it took me two or three attempts  but i got there in the end 

Your idea would probably work a bit better depending on the radius of the corner. The rounded edge from an ellipse is a bit more er, rounded. Or can be.

Still, some different ideas for the OP to try 

P.S. It might be easier to draw a rectangle, add a couple of nodes and "lose" one corner before adding a circle ?
