Question

The front view of a line AB measures 75 mm and makes an angle of 50 with XY. The end A is in the HP and VT of the line is 25 mm above the HP. The line is inclined at 35" to the VP. Draw the projections of the line AB. Determine its true length

Answer 1

Answer:

here are the steps to draw the projections and determine the true length of line AB:

Draw the front view of line AB measuring 75 mm.

Create an inclined line at an angle of 50° with XY from point A.

Draw the vertical trace (VT) of line AB 25 mm above the horizontal plane (HP).

Extend the inclined line at an angle of 35° to the vertical plane (VP) until it intersects the VT, labeling the point as B'.

Draw a horizontal line from point B' to intersect the inclined line AB, labeling the point as B.

Measure the distance between points A and B to find the true length of line AB, which in this case is 75 mm.
