Bill,
I'll be darned! How is it that I never saw that in Corel? Your solution is greatly appreciated.
Now that you explain it, Xenetech has a function to display and change direction of polylines and the older ScanVec programs used the direction when routing to determine which was the inside and which was the outside of the object for inlay applications. But, thousands (maybe 100s of 1000s) of times I've combined shapes from every conceivable source (I thought)and never had that happen; so, I didn't think the "clock sense" was relevant in Corel.
After reading your post, I spent more time than I have available to understand that a bit better, but I still am a little fuzzy on how it works. For instance,
create a square, fill with a color,
put a circle inside,
convert both to curves,
make duplicate of both and move aside
in one, select nodes in circle and reverse order
finally, combine them and regardless of direction, holes are in both
What's the difference between this and our sample problem? Roy Brewer
