1. The problem statement, all variables and given/known data A line Ab inclined at 30• to the Hp has its ends a and b, 25 mm and 60 mm behind the vp respectively. The length of the top view is 65 mm and its vt is 15 mm below the Hp. Draw the projections of the line and locate its ht. also, determine the true length of the line Ab and true inclination of the line with vp. ht means horizontal trace. 2. Relevant equations 3. The attempt at a solution I have drawn the plan of the line, located its VT but now stuck how to draw the elevation of line.
