Never cross a _____________ line.
Dimension
What what is the distance to the first dimension from the object line? Second, third, forth, etc. dimensions?
3/8 of an inch then an additional 1/4 per extra dimension.
No dimensions on views except for:
Radius
Leaderlines can be at any length and any angle except for which angles?
90 and 180
Keep dimensions between views unless:
They are hitting other dimension lines, there is no room for them between views, you get a better description of the feature by dimensioning from the outside, or the only way to dimension between views is to a hidden line.
Used to transfer depth dimensions between top and right side views.
