That seems to be where it is breaking. However, I can't seem to find any way in the roughing plane operation to prevent this from happening. I know in waterline, we have the options of doing depth first vs level first, and something like that in the roughing plane seems to me like it would solve the issue. Any thoughts? (Also, if that explanation makes no sense, I'll add a picture of what I'm talking about later tonight).
