I have build a complex compound with both addition and subtraction. Now I want to convert this to a single curve. Is there a one-click (or similarly easy) way to do this, or do I have to manually rebuild it from the components using destructive boolean operations rather than compound operations?
Combining two shapes with the alt-key to crteate a compound shape (as shown in the lesson Affinity Designer - For Beginners Too) changes the top shape making the operation totally useless.
