Step-by-Step Construction
- 1
Draw the front view and top view of line AB
- 2
Extend the top view until it meets XY - this gives VT (Vertical Trace)
- 3
Extend the front view until it meets XY - this gives HT (Horizontal Trace)
- 4
VT is the point where line meets VP (distance from HP to VT)
- 5
HT is the point where line meets HP (distance from VP to HT)
- 6
Verify: VT in FV lies on XY, HT in TV lies on XY
Pro Tips
- •Always verify your measurements with a scale before finalizing the drawing
- •Use construction lines lightly and darken the final solution
- •Label all important points and reference lines clearly
