Use the finished drawing from Problem P8–7 to complete this problem. Construct profiles A-A, B-B, C-C, D-D, E-E, and F-F shown in Figure P11–6. Profile D-D cuts through the transit station, point A. The other profiles are 50? apart. Each profile should be only as long as the distance between property lines along the profile. Draw the profiles using a 1?? = 100? horizontal scale and a
1?? = 10? vertical scale on an appropriate size sheet. Show all profiles on a single sheet. Label vertical elevations and indicate horizontal and vertical scales. Label each profile with a title, such as PROFILE A-A. What will be an ideal response?What will be an ideal response?
