Setting supports paths using ...
A undocumented method of adding support paths in Autocad was to add 3 periods to the end of support path, the 3 ... meant look further down the tree automatically, so this helped with say
\mycompany\LIB... so below Lib was say multi library directories.
I have access to both Acad and Bricscad and both do not seem to support this. Its a hard thing to look for on the web hence asking here.
