Guest Posted November 7, 2018 Share Posted November 7, 2018 I have a ring / donut shape. On top I have a square, at an angle. I am trying to subtract the square from the ring, to create a letter C. But Affinity Designer doesn't seem to be able to do this. All I get after subtracting is a weird shape. See below: I've just retried the subtraction and it now works. I've tried a third time and again I get the strange shape. It is inconsistent. CW logo big C.afdesign Quote Link to comment Share on other sites More sharing options...
v_kyr Posted November 7, 2018 Share Posted November 7, 2018 When I open your attached file I can see the following, which is what I would expect as the result of that subtract operation.

Staff MEB Posted November 7, 2018 Staff Share Posted November 7, 2018 Hi Markeeee, Welcome to Affinity Forums We are aware of a few issues with the boolean operations (already logged to be looked at). It's possible certain cases fail to give correct results or generate superfluous objects. We hope to improve this in future versions. Thanks for your report.

gdenby Posted November 7, 2018 Share Posted November 7, 2018 Yes, I was able to duplicate the behavior. Tried duplicating "donuts" & diamonds, and donuts and rotated squares. The anomalous results happened about half the time. The position of the corner of the diamond/square was at the center of the donut. I found that it the corner was shifted away from the exact center, the results were as expected. This also happened w. the composite operation.

It would be easier to do that with a single Pie shape. Then you get all the benefits of Affinity's dynamic shape editing. Set the Hole radius to make the hole in the centre, then you can drag the red handles to where you want. P.S. I love pie firstdefence 1 Quote Windows PCs.

The first boolean operation I need to do in Affinity and it can't do it. And it's the easiest subtraction. This really sucks. Quote Link to comment Share on other sites More sharing options...
Staff MEB Posted November 7, 2018 Staff Share Posted November 7, 2018 Hi Markeeee, I'm sorry it didn't work for you right on the first time. As I mentioned we have this issue logged, along with some sample files for us to test against new/revised code. Most boolean operations should work reliably but there's certain cases where the code does fail. I understand it can be frustrating. We are doing our best to fix those and other issues. Thanks for your understanding. Quote A Guide to Learning Affinity Software Link to comment Share on other sites More sharing options...
gdenby Posted November 7, 2018 Share Posted November 7, 2018 Hi, Markee, You just got lucky. I've been using Designer for over a year now, a minimum of 2 hours a day, sometimes 6, and this is the 1st time I've run into this. As toltec mentioned, the usual practice would be to convert the ellipse to a donut/pie. Also, I messed w. various shapes of triangles. Didn't get the problem. Seems like this problem is limited 2 those 2 shapes, in exactly that alignment.

I've just tried combining two shapes and the same problem. And this is the first time I've tried combining. So two attempts and both fails. I get weird shapes. I'm following the tutorial video here: https://vimeo.com/153090767. I've made the "blood" shapes at the top of the page and then tried to combine the tear drop shape (using the ALT key so it is non-destructive). And it just produces weird shapes. Although after trying several times it now works and I can't now get it to not to work (I'd have liked to have posted it on here)! Quote Link to comment Share on other sites More sharing options...
Staff MEB Posted November 12, 2018 Staff Share Posted November 12, 2018 Hi Markeeee, Currently there's an issue with smart nodes/boolean operations as used in that video that makes the operation to fail. To work around the issue select the all the smart nodes (draw a marquee around all nodes) from the bigger shape with the Node Tool and convert them to Smooth Nodes clicking the respective icon in the Convert section in the context toolbar. You should then be able to perform the boolean operation as described in the tutorial. Quote A Guide to Learning Affinity Software Link to comment Share on other sites More sharing options...
Lauer Posted May 28, 2020 Share Posted May 28, 2020 I am literally creating this same shape and having the exact same problem... so almost 2 years later and the same problem persists? Quote Link to comment Share on other sites More sharing options...
Guest Posted September 1, 2022 Share Posted September 1, 2022 Has this been resolved?? Is it now possible to subtract a simple shape from a simple shape and get the correct result? Quote Link to comment Share on other sites More sharing options...
PixelPest Posted September 1, 2022 Share Posted September 1, 2022 Not sure why you´re not trying by yourself. I´d say it´s working even with parametric shapes: Quote Link to comment Share on other sites More sharing options...
