Discovered a nice little thing the other day that I thought I'd share, some of you will no doubt already know and some of you may not:
If you link a dimension value (such as the thickness of a shell) to the name 'thickness' then suddleny the tick-box appears in the boss extrude/cut dimension, as for sheet-metal.
Also, linked values can be linked to in the document properties dialogue - I didn't know that either until the other day!
Hope you're all having fun!
