| Title | 16 cmd computes incorrect lengths at curves MOD. |
| Description | The 16 command incorrectly computes a rounded integer value for the remaining interval when the station interval lies across the PC or PT of a curve. The example in the comments below generates incorrect points based on an invalid length of remaining arc and/or tangent needed to complete the station interval. Modified 3/29/2000 SET. Added a 77 command to the sample data file below to show how the stations are actually being computed. All the stations should be exactly 20 foot increments for computed points resulting from the 16 command. The only exception are points that correspond to the pc and pt of a curve. All other stations are exactly 20' increment values as in 0+0, 0+20, 0+40, 0+60, 0+80, 1+00, 1+20, 1+40, 1+60, 1+80, 2+00,2+20, 2+40, etc. |
