I’ve updated the contraption to version 3, which leans harder on Lil’s “conforming” to calculate the curve rendering. As a result, the ten-handle curve that was “very laggy” on my computer before (with the Script Profiler capping out at 100% CPU usage) is now smooth (capping out at 64% CPU) even at the default step-size of 2. The new version still has a step-size property, though, because somebody might want to draw an even bigger curve. :)
