This dimension is set parallel to the slanting surface, with extensions  
perpendicular to the dimension. The text is set outside of the dimension with 
attention paid to the text orientation. Use either 45° short stubs or arrows. 
When using these dimensions remember that the starting
position refers to the item.

In essence apart from the complication of the angled geometry, it follows 
much the same pattern as the outer dimension. Specify the dimension position 
by giving two coordinates on the object, ptA and ptB, at a perpendicular 
distance
of the extension, extA, alternatively give the start position and angle with
dimension length. It is assumed that both extensions are of equal size.

If the text lies on the wrong side of the object simply change the angle by 
180°.
