Hi Alex,
I just select all paths then index through them with the knob selecting pipe or box with the switch and applying.
When trying to do the Boolean operation on all of them at same time caused problems.
Cheers
Barry
Update;
you can try bypassing the index select and plugin directly into the RevSwitch.
Just tried with 100 curves and it took 20 sec for pipe and 30 sec for box.
Any problems you can revert to index select.
