Key steps;
An Auxiliary Elevation is projected from plan.
The heights are taken from Elevation
The X1Y1 line must be at a right angle to the projection lines.
If you want to see the true shape of a surface your projection lines must be at a right angle to the "edge view" the surface. This is because the true shape is what you see when you look perpendicular to a surface
