I am creating family tables in lower level assemblies containing different options. Exa.-xxxx-a contains a mule drive frame bracket, xxxx-b contains a shaft drive frame bracket. Then the frame itself is assembled with the engine assembly, and this is assembled into the top level assembly. My question is if there is any way to carry my family tables onto the top level assembly? So from the top level assembly I can change options all the way down to the lowest level assembly. I know I can do it by creating new tables in each level containing everything from the previous levels, but is there any way to tie them together and build on each all of the way to the top.
