Good morning everyone,

Quick question on angular dimensioning in drawings.  For the longest time I've been sketching a vertical "construction line" within the drawing itself in order to be able to dimension off a vertical reference.  Is there a trick that I'm not aware of that will allow me to refrain from this added work if I don't have to?  Basically, if I have a horizontal line and angled line, I can only dimension between the two to get 38 degrees, but the shop prefers a dimension off of vertical.  Hopefully my attachment will clarify.  I marked in red the little vertical line I stick in there to allow for the dimension to be pulled.  Thanks!
