Did you try doing a search for "descriptive geometry?" I found a lot of hits.

This is an older book but you can download it in PDF form:

are each three of the views on different planes that are perpendicular to each other, for example: top, front, side?

if they are then find lengths of the lines in each view. say L1,L2, and L3

to find the true length the formula is: sqrt[(L1^2)+(L2^2)+(L3^2)]

this is the 3D formulation of the pythagorean theorem.

if 1 or more of the view planes are not perpendicular to the other two and the line is not parallel to at least 1 plane then you'd need to find the angle at which the planes intersect each other and through a more tedious calculation you find the true length.

what program are you using?

If they're learning the way they should, the program is called a pencil-paper-tsquare v1.0.

lol, i actually googled that.

i only asked because i dont know how profile, horizontal, and front relate to each other.
