I created a hatched sketch on one of my views to represent filler material. I want to balloon to this hatched area, but it want grab it. I have the filler material setup as a custom part. I can also create a sketched symbol for this if that would help, but it doesn't appear that they would accept it either.
I am currently running Inventor 2010 Build 272, Release: 2010-sp3
The only way that i know its add a baloon in a part first, then drag the arrow to the sketch edges of that virtual component.
