Corner Tool doesn't work to some corners after subtraction

[iconoclast]

Hi!

As you can see in the attached images, I created a rectangle and wanted to make some sort of label form outoff it. So I created four circles, placed it on the corners of the rectangle and subtracted it. Ater that, I used the Corner Tool to round the corners. But this last step only worked for some corners. Not for all. It seems that some of the corners had become converted to curve points, while others didn't. So these edges could only be formed by using the Node Tool.

I tested it in different ways. At first I subtracted every circle, one after the other. Then I added the circles together before I subtracted it and at last I added two at a time and subtracted every pair after each other. As result I got different numbers of edges that were converted to curve points on different places. But it didn't word well in any of this cases.

In the first attached sample the lower left corners don't work. The selected one is somehow blocked, the other one is a curve point. In the other sample three corners are curve points, as you can see.

There’s probably something irregular about the outcome of the subtraction operations, but in this particular case there’s a much easier way to achieve the desired end result. Just use the appropriate Context toolbar option for the original rectangle:

Hi Alfred!

Excellent hint! Works perfect and much easier than my workflow. Thanx verry much!

Hi iconoclast
Check if there's two nodes too close or even overlapping on these corners or alternatively can you attach the file to be inspected please?

[iconoclast]

Hi MEB!

I already deleted the file, but I created a new one. This one surprisingly only has three corners that can be manipulated with the Corner Tool - three of eight! I attached the file with its history, so that you can follow the steps I made. Hope that helps anyway.

Thanks iconoclast. The boolean operation is creating smooth nodes where they should be sharp thus the Corner Tool doesn't work on them. I'm logging this to be looked at (if not logged already).

Thanks for that, MEB!

May I also know if corner tool can work on all points? It seems to work on non-curve lines

[BelAffinity]

Sorry just to clarify my question, the Corner tool only works on angular corners and not on all points?

It only works on ‘Sharp’ nodes, not ‘Smooth’ or ‘Smart’ ones.

Oh I see that's sad

If you particularly need or want to use the Corner Tool on nodes which are not sharp you can simply select and convert them beforehand.

I found out something new about the problem. It has to do with the accuracy I placed the circles I subtracted. If the center points of this circles are placed exactly on the corners, there will be no problems with the Corner Tool. If the center points are placed just a little bit inside the rectangle, there will be one or two additional nodes after subtraction, that result from the circles, that are based each on four nodes. These nodes impede the Corner Tool. Seems that it is logical behaviour and not a bug.

Hope you understand what I mean. My english is verry bad. If not, just ask.

Edit: To make the nodes usable for the Corner Tool, it can be helpfull to rotate the circles a bit before subraction.

I attached four images that illustrate what I mean. On the second one, you can see the additional nodes, taht result from the circle. On the fourth one I rotated the circle, so that the nodes don't disturb.

Not sure if it is related, but when I created an ellipse, then a square and used boolean add to these, then alt-drag it to the right and add a rectangle in between to make a handlebar, i found out that when converting the handlebar to curves, the corners behave odd, and bug out the object.

Selecting both corners in the corner tool and dragging it has the following effect:

 

Note that when I undo this action and only do that on the right corner it works as expected:

However, when moving on to the second corner, it instantly reverts back to the inverted state (without touching it):

 

When alt-dragging the whole bar to create a duplicate, it looks like there is 1 point (not selectable by the corner tool) that is stuck

 

Now I'm a beginner so I may just be doing something horribly wrong and not have noticed.

If not, I believe this demonstration should be useful to debug the problem regarding boolean operations preceeding corner operations.

Hope this helps.

Yes, that happens to me too. Not sure if it is a bug. But you can easily fix the problem by selecting the corner point where the problem exists, and then click on the button marked on my attached screenshot.
