I know this is waaaay old, but the forum's search function doesn't work for me...
Anyway, this OP asked the exact same question I wanted to. One response said "Can't do it" then the last responder said to go to tweak view, select all the components in the browser that are listed under the tweak then "APPLY A NEW TWEAK TO THOSE COMPONENTS"
So this was back in 2005, and I think either that guy was smoking something or Inventor has taken a huge step backwards. Because although I can select all those parts in the browser, and THEY ALL HIGHLIGHT IN THE GRAPHINCS WINDOW....
Get this...
There doesn't seem to be a way to apply another tweak to the selected components. MAybe there was in 2005, but I'm banging my head against a wall here. The components are selected...good...everything highlights in the graphics window...good...then I RMB and pick "Repeat Tweak Components"...
THEN...
The parts all deselect, unhighlight, and I'm prompted for a direction vector. No way to select all those 132 components again?
Really?
What am I missing that this guy found back in 2005?
