I’ve been getting complaints from users that the waterline toolpaths cause the program to lockup lately. I haven’t been able to repeat it on my machine until I get an email from Florian today. Something he said jogged my brain a bit and I realized that the problem was with the new multicore waterline code. Single core machines would freeze but machines with more than one core would work fine.
I just posted an update that seems to fix it in my testing. If you have had the freezes then please let me know if this fixes it.
