Why using a datum plane to set the extrusion boundary? In case you want to replace it by another face for example? Because if its just for the extrusion-lenght I don't see the advantage over just stating the 30mm in the extrude itself. It makes no difference, where you change that number, still have to do it one time!?
@@Bizlearn_Siemens_NX_Training missed the last two times (had to rewatch). I definetly see the difference to referencing the top of the extrude als plane
