Plane parallel to HP

Plane inclined to HP

at 45 and ┴ to VPSide on the H.P. making 60

with the VP.

Read problem and answer following questions

1. Surface inclined to which plane?______

2. Assumption for initial position? plane // to ____

3. So which view will show True shape? _______

4. Which side will be vertical? ___________

Hence begin with __,draw hexagon ______

X-Y line, taking one side vertical.
