pocket facing boundaries issue

[Hintze]

first off, im following a caminstructor video, ive done everything the instructor has shown, but im getting an error. im trying to pocket face my part to mill down my stock while avoiding a 2" circle, i use pocket mill, and chain select, select my first chain for the outside of my stock and then go to select my second chain to avoid my 2" circle. but it gives me and error saying "not all boundaries are closed. select open pockets or closed chains"

or ill get an error saying "the selected sub-chain does not touch the branch point" what is this exactly telling me to fix.

Sound like your chain are not trimmed together all the way around,  trim your first chain at all intersection, and make sure they are all on the same z level

 

hope this help
