Question

A line AB, 80mm long, makes an angle of 30° with the V.P and lies in a plane perpendicular to both the H.P. and the V.P. Its end A is in the H.P. and the end B is in the V.P. Draw its projections and shows its traces.​

Answer 1

• PROJECTION OF LINE
• PROJECTION OF LINE2.  A straight line is the shortest distance between any two points in space.  A line represents the locus of a point moving along a fixed linear path in space.  As a line consists of a number of points, its projections are drawn by joining the projections of any two points on the line (preferably the end points) or on the extension of the line.  RP`S means VP and HP.

Projection of Line3. SIMPLE CASES OF THE LINE 1. LINE PARALLEL TO BOTH HP & VP. 2. A VERTICAL LINE ( LINE PERPENDICULAR TO HP & // TO VP) 3. LINE INCLINED TO HP & PARALLEL TO VP. 4. LINE INCLINED TO VP & PARALLEL TO HP. 5. LINE INCLINED TO BOTH HP & VP. Information regarding a line means it’s length, position of it’s ends with HP & VP, it’s inclinations with HP & VP will be given. Projection of Line AIM:- TO DRAW IT’S PROJECTIONS - MEANS FV & TV.

Terms used in Projections of Lines  True Length (TL): The actual length of a line is called its true length.  Plan Length (PL) or Top View Length: The apparent length of a line seen in TV is called the plan length or top view length.  Elevation Length (EL) or Front View Length The apparent length of a line seen in FV is called the elevation length or front view length.  Side View Length (SVL)The apparent length of a line seen in SV is called its side view length.  Inclination with the HP (θ): It is the true angle that a line makes with its projection on the HP. It is indicated by θ (True inclination with HP).  Inclination with the VP (Φ) It is the true angle that a line makes with its projection on the VP. It is indicated by Φ (True inclination with VP).
