The Tip Box following Step 1 mentions the use of sketch geometry, This referenced geometry (construction lines?) is apparently not visible when the sketched symbols are inserted into a drawing. The Construction button and the Style pull-down box are not available in sketch mode within idw files. How are these referenced lines made invisible when the sketch symbols are inserted?
Note: The above procedure references Inventor 2008, I am currently using Inventor 2009, 32-Bit Edition, SP1.
