Sorry, I alt-Tabbed and posted, it seems, a blank question :/
I'm trying my damnest to get around a problem I encountered trying to cut a circle within a circle (to create a ring). Whichever method I use the result is the same - a ring with a fill that covers the space that was cut out (see attachment).
Weird thing happens when I make a cut outside of the shape (attachment 02) - the fill in the centre disappears.
What is going on here? Is there a way to fix this?
Corel has MANY glitches that I encountered but this is deal-breaking. One of the core features and it dosent work as it should.
Dont get me started on support. Its NON-EXISTENT
Is this the result you require (apart from the lack of teeth)?
There is some weird combining going on here, which is unexpected and I suspect is a bug. I'll look at that in more detail later.
At the moment, because of this I can achieve the above only by:
If that's not the result you want, perhaps you can post a sketch.
Trim should definitely work perfectly fine with two simple objects like these, and I'm pretty sure it does too.
What I suspect has happened here is that both the inner and outer subcurves are running in the same direction (either clockwise or counterclockwise) AND the object is set to use the non-zero winding rule for some mysterious reason, instead of even-odd which is default for ordinary objects *. This sometimes happens with imported objects.If the subcurves are running in the same direction with non-zero winding rule, the hole will be the same color as the outer curve.There is one simple thing you can do to correct it: Select the object, switch to Shape tool and select one (or more) nodes on one of the subcurves.In Property Bar, click the "Reverse direction" button. This fixes the problem with the curves running in the same direction and should open up the hole.
* These two rules for how curves interact is not something Corel made up.Ordinary objects should be using odd-even by default but text objects use non-zero. This to avoid that script text (for example) gets holes where characters overlap when it is converted to curves.In Draw X7 (but I don't think in X6) there is a checkbox in the Object Properties docker to specify whether to use the non-zero (also called "winding") or odd-even rule.Here's an example with text converted to curves:
Two places for reverse subpath. One on the properties bar when the shape tool is active. The other place a right click on the path with the shape tool active.
Edit:
Something happened with my screen shot. There is nothing there, but that is where it appears. I must have clicked off the tool. It looks like two curves with arrowheads on opposite ends of each.
