Question

When the plane is parallel to h.p and perpendicular to v.p and p.p is always first

Answer 1

When the plane is parallel to h.p and perpendicular to v.p then p.p is always b.v first

• If a plane is parallel (pp) to one of the reference planes, the parallel projection to the plane gives the true shape and scale as the plane here is parallel to the horizontal axis, the real shape is viewed from a top view.
• Whereas if a plane is parallel to h.p and perpendicular to v.p, then pp is always back view (BV) first.
