LINES & RECTANGLES 1 § Three ways to enter a point: I. ABSOLUTE COORDINATE Ø Points enter relate to the origin of the WCS Ø Enter point as X , Y II. RELATIVE COORDINATE Ø Points enter in relation to the first point entered Ø Enter point as @X , Y Ø Line is drawn from the first point to another point X units over and Y units up relative to the previous point III. POLAR COORDINATE Ø Draw a line at certain distance at a particular angle Ø Enter line as @D<A Ø D = distance , A = angle DET 111 – ENGINEERING DRAWING Dr. Suzanna HR & En. Mohammad Isa AA
