I have a query regarding inserting single purlin cleat connections. It can be imputted for instance on the lower side of the purlin on a sloped rafter, however when I try to install it on the opposite slope it automatically installs the connection on the upper side of the purlin. I have tried mirroring etc. but this will not work. I do not want to delete joint box and do it this way as it makes it far more difficult to copy in transform elements. I would appreciate any assistance.
