Not really a question as it never bugged me for too long but sometimes certain commands, Sweep2 especially, will not work even though everything in the base curves/surfaces is fine. What I found out after a lot of frustration is quite simply rather than remodeling everything, just trying again… sometimes I have to try 2,3 times for the command to work, sometimes I have to isolate the objects or rotate/zoom the viewport.
So not really looking for help as it usually works out, but just curious as to why it is so.
Also the isolate command in WIP is probably the best thing after sliced bread and is the only macro I run on rhino5
