- Transfer dimensions D1 and D2 from the horizontal view
to locate point 1A and 2A along the projection lines in
auxiliary view A. - Connect points 1Aand 2A. This is the true length of line1-2.
The true length of an oblique line can also be projected from
the horizontal views and profile views using the same basic
steps as described above.
