Projection Of Line Line Inclined To Both The Planes Class In this lecture, projection of lines inclined to both the reference planes is demonstrated. To solve the problem: 1) draw the top view parallel to the xy line since in that case the front view will show the true length. 2) extend the top view to determine the true length of 75mm. 3) use trapezoidal method to determine the inclinations of the line with the principal planes as 30 degrees with the horizontal plane and 48 degrees with the.
Projection Of Lines Inclined To Both Planes Engineering Graphics Draw the horizontal locus lines through b 2, and. b. 6. with center a and radius ab1, draw an arc to cut the locus line drawn through b2 at b. connect ab, the top view of the line ab. 7. with center a' and radius a'b. 2 , draw an arc to cut the locus line drawn through connect a'b', the front view of the line. Projection of lines inclined to both planes. theory: true length: actual length of a given line, length of the projection is less than the length of true length. theta: it is the angle made by the actual line with hp (wrt to xy line) phi: it is the angle made by the actual line with vp (wrt to xy line).

The document discusses different types of projections of points and lines in space. it describes 9 types of point projections based on their location relative to the horizontal and vertical planes. it then explains the different notations used for projecting lines, including their true length, front view length, top view length, and inclinations.
