Boolean operations still messy

[Wurstkäs]

Hello to all Affinities,

my first message as an old reader of the forum. And as often said: "I like the Affinity-Software, but …"

I am a little bit annoyed, that the boolean-operations still are very messy and unpredictable. I think, these are basic-funtions but there are very little improvements over the years.

As you can see: the trapezoid shape combines inaccurate and the round shape combines in no way and disappears at last. Funny.

I will gladly pay my amount for a more useful 2.0 version of your software.

Please apologize my limited english.

Best wishes from Munich, Germany and stay healthy

Hi Wurstkäs,

Thanks for letting us know.

This is something we're aware of and with development to be fixed. I will get your comments passed over.

I tried to replicate it but no luck.
To better understand what's going on, it's a good idea to try the compound feature first, rather than destructive boolean. Simply option-click the button instead (or Layers > Create Compound), then the original curves will remain intact and editable. See then also the Layers panel. You can then zoom in and inspect the original nodes. Sometimes, such strange things happen because of duplicate, almost overlapping nodes, or curves not being closed although they appear so.

Hello Loukash,

the strangest thing is, i tried to replicate this behavior in another document and everything was alright! No failure. But in the document i showed above everything is messy.

All documents made with the 1.9.2 Designer version.

Would it be possible for you to attach the offending document at all please?

Hello Sean,

here is the file.

Something weird is happening there:

replaced *.mov with *.mp4

It's a weird easter egg i think!

Thanks for the files. I'll get them passed on. The Cloud like objects however consist of two 'curve' objects (Hence they're Kurven and not Kurve in your screenshot). This is what is making the operation fail for them. If you go to Layer > Geometry > Separate Curves you will see it will split them into two objects, one being a small triangle which can be deleated. You will then be able to use the Boolean Operations on these.

Interesting and good to know! I haven't noticed this semantic distinction yet.

Hello Sean,

thank's for the explanation. Curve vs. curves. Very tricky.

But where does this little invisible triangle come from?

An artifact from an earlier boolean operation that you must have performed with the object.
Depending on the starting forms, Affinity's boolean operations may lead to unexpected and undesired results. Known and acknowledged issue for sure, unfixed since years.
