1.	If top view of a line is a point, its front view is ____________(a) parallel to xy line and of true length(b) parallel to xy line and of apparent length(c) perpendicular to xy line and of true length(d) perpendicular to xy line and of apparent lengthI got this question in an international level competition.The question is from Projection of Straight Lines topic in division Orthographic Projection, Projections of Lines, Planes and Solids of Civil Engineering Drawing
Answer» The correct ANSWER is (c) perpendicular to xy LINE and of true length Easiest explanation: When the line is PARALLEL to the vertical plane and perpendicular to HP then it will FORM a point projection on the HP and so the APPARENT and the true inclination will be same of the line as it will resemble a point projection.
