weldments cut list help

Hello all,

Ive created a rising road blocker base from steel as in the picture attached, the problem is ive no cut list option in tables!

Each piece has been made in parts and ive right clicked on cut list and selected update.

All parts have been assembled in assembies as normal and mated together, not had this issue before :-(

Am i missing something obvious here?

thanks in advance

Oliver
