I'm having an issue with a drawing that I have never had before.  It's a front grille of a vehicle and it is contoured from left to right.  There are no flat parts on it.  In the drawing I need to use the sketch that is in the part file to dimension to.  Now when I go and hide the sketch all the dimensions hide also.  Not all the dimensions but the ones that are attached to the sketch.  Actually, only the dimensions that dimension vertically.

Has anyone seen this before?  I've been on SW for over 8 years and never came across this.

I have attached a Word file for you guys.
