Section Sample

This tool forms sections in the model by sampling predefined surface(s) at specified increments.

Keyboard Command: SecSmpSur

Procedure:

1. Choose a predefined centerline using the popdown list.
2. Select the predefined surface(s) to sample using the check list.
3. Enter a name for the section series or take the default (see notes).
4. Build a list of stations to sample (see notes).
5. Choose additional options as desired.
6. Click the OK button to begin processing.

Notes:

• The Section Series string must contain [SurNam], the program will substitute the surface name during processing.
• Stations lists can quickly be built using one of the methods in the adjacent station list builder.
  • The (+) option lets you specify starting/ending values and an interval.
  • The (...) option lets you select an existing series (tied to the same centerline) to match stations in that series.
• Sample Distance defines the distance along the section (left/right) to sample points. This will equate to the (horizontal) distance between the points in section view. Use a smaller number for smoother sections.
• The Minimum Left & Maximum Right values should be set to previously determined values. If the number is too high the routine could pick up undesired points, especially in (near) U shaped curves.
