Snap to edge/face (slide the vertex along the edge its snapping to or on 
the plane of the face)
Snap to Vert
Snap to Centre (of edge or face....)
Snap to bound box.....
Snap to Normal (so you can move a vert away from an edge along the 
normal of the edge its snapping to)

Snapping is more important in CAD packages which don't actually use 
Verts as their main construction method,  as then you have functions 
like Snap to tangent, snap to curve, snap to centre (of a circle for 
example)  snap to quadrant......

blender could still use Snap to curve, snap to tangent... if its 
implemented for curves also.  but then blenders snapping would need to 
access the original curve, not the drawn curve (which is verts)

dimensioning should be 2d (or rotatable via an angle) and should measure 
the distance between two choosen points,  these two choosen points 
should be anything from verts to curves to edges....  the measurement 
display should then be moveable indipendantly (as an object) with 
projection lines going to the two points)  Dimensioning should have 
similar properties/panels as fonts/text

Not CAD per-se, but somthing good enough for basic GA's
