I've been meaning to post about this but haven't had the time. I'm having the exact same issue as Ryan on, I believe, every instance of 2D Chamfer. While it will regenerate the toolpath despite the error, if you edit the toolpath, you cannot click "OK" until you've deleted the unit. It will then temporarily show no error, but the moment you edit again (or save the file and open it again later), the error will appear again.
This is one of those things that doesn't *technically* limit me in any way, but I firmly believe that spurious/incorrect warnings/errors really need to be addressed ASAP. These sorts of things train users to ignore warnings, causing them to miss valid warnings or errors when they come up.
Since I've found time to reply, I'm also going to piggyback on this and suggest that Fusion should have a better solution for warnings/errors in general. Fusion is a large, actively developed system that's trying to develop sane defaults that are correct for the majority of users, but this means a lot of spurious warnings. An example and my personal pet peeve: finish feedrate is higher than cutting feedrate (finish feedrate occasionally should be higher than the cutting feedrate to account for chip thinning). The problem is that there's no way for me to say, "Hey, Fusion, I'm cool with this situation, please don't warn me about this." Instead, my Setup now has a warning indicator that will forevermore mask warnings I may actually care about.
A solution to dismiss warnings (and possibly even "errors", such as the one that spawned this thread) would be really helpful in maintaining files/setups that occasionally "break the rules" without inuring users to warnings as a whole.
