nothing I've tried works to get me the desired result:
fp.jpg--which is, to cut away the rectangles AND leave an open "stencil" cut, as shown. Doesn't happen, Corel ALWAYS closes the opens, as shown in my graphic.
I've also tried every variation of grouping, combining, double and triple segments, hand-drawing line by line- doesn't matter, never works.
Can't find any help in the 'help' section or options.
The only way to get the desired result is to cut out the opens after the fact.
