The Line Is Inclined To Both The Reference Plane Problem 1 1. a line ab measuring 80 mm long is inclined at an angle of 30o to hp and 45o to vp. the point a is 20 mm above hp and 30 mm in front of vp. draw the proje. In this lecture, projection of lines inclined to both the reference planes is demonstrated.
14 Projection Of Lines Inclined To Both Reference Planes Problem 4 Short video explaining the step by step procedure to obtain projection of given line which is inclined to both reference planes (i.e. hp and vp) this is the. 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 distance between end projectors of the line, when measured parallel to the line of intersection of plane is 50mm. draw the projections and find its inclination with vp. st ra 13. line ab has its end a 15mm above hp and 10mm in front of vp. the end b is 55mm above hp and the line is inclined at 300 to hp. Solution steps: draw a reference line xy. mark point p ́ at 15 mm above xy and point p at 15 mm below xy. draw 60 mm long lines p ́q ́ and pq, parallel to xy. draw a line from point q ́, inclined at 120° to xy such that it meets the horizontal line at 50 mm above xy at point r ́. join q ́r ́ and p ́r ́.
