Sample Line From Corridor Stations Image


HINT: Typically the only sample lines you should be pulling are the ones that are where your corridor stations are. If you choose anything else you will not see your design or if you have pulled surfaces from your design, you will see non-daylighting links when they are supposed to daylight. This is due to the fact that any station other than the designed stations are interpolated.

Set the station range and swath widths:
  • Set the values then click OK
  • Close the Sample Line Tools (click on the X) to save the sample lines.

You will see the lines appear on the screen.

Sample Line Example Image


HINT: Sample Line Swath Width is the tool used to control the centering of the section of the 0 offset axis. Here is a tested list of swath widths to place the 0 offset at the centermost major vertical axis. Theoretically the values are linearly proportional - i.e., 40 scale shows a 280 swath. 20 scale should be able to get the same results with 140. 10 scale should use 70 for swath width.
