Engineering drawing - projection of lines

Click For Summary
SUMMARY

The discussion focuses on the engineering drawing of a line Ab inclined at 30 degrees to the horizontal plane (Hp). The line's endpoints are positioned 25 mm and 60 mm behind the vertical plane (vp), with a top view length of 65 mm and a vertical trace (VT) located 15 mm below the Hp. Participants provided solutions for drawing the projections of the line, locating its horizontal trace (ht), and determining the true length and inclination of line Ab with respect to the vp.

PREREQUISITES
  • Understanding of engineering drawing principles
  • Familiarity with horizontal and vertical planes in projection
  • Knowledge of true length and inclination calculations
  • Proficiency in using drawing tools for technical illustrations
NEXT STEPS
  • Study the principles of line projection in engineering drawing
  • Learn how to calculate true lengths and inclinations in 3D geometry
  • Explore software tools for creating technical drawings, such as AutoCAD
  • Review examples of complex projections involving multiple angles
USEFUL FOR

This discussion is beneficial for engineering students, drafting professionals, and anyone involved in technical drawing and projection techniques.

Homework Statement


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.

Homework Equations


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.
