This is something i used to do ALOT in inventor and solid works, is there such a mate in solid edge?

Is it even possible to create a reference axis, similar to that of inventor and solidworks?

I am attempting a tube construction, a large diameter tube is to have two smaller diameter tubes pass though its centre. I can cut the odd-ball angled holes out of the large diameter tube no problem, i can align the smaller tubes to cut outs, but i would like to mate the tube centre of the smaller tubes (identified by a sketch line) to the centre plane of the larger tube. again something i used to do all the time with inv. and sw.

Thanks for any help in advance.
