As an example, T-joints shall serve. In the image above you can see for the connection '*perpendicular from the front*' the standard case that always occurs: the entry '*(current lead file)*' This entry is for the connection where the abutting and the abutted wall have the same HRB lead file, namely exactly the file that is currently being edited.

If you double-click the entry '(current lead file')' the settings dialog box for this connection opens directly and you can configure the penetrations, posts, and connections of the sills and frames.
