hi michael yes was thinking along those lines; as i saw some holes in the above thread (already extruded and part of a solid being moved around). i iwas curious if theres some smart way to make punched out or pass through holes all change size quickly in a click or two, eg could this also work with holes in sheet metal. typical example change all 5mm pass through holes in 3mm aluminium sheet to 5.3mm. i dont relly want to have to select all the indicidual holes just select the "named object" change the radius / diameter and maybe the object type name to "hole 5.3mm" and they all change...fyi: just back from a trip and not in work mode or front of pc with your new beta installed.
