Section Sample Lidar

Applies section sample lines to a lidar file to pick up data band.

Keyboard Command: SecSmpLid

Procedure:

1. Open or create a drawing containing an alignment, section sample lines and optional section views.
2. Initiate this tool from the menu, ribbon or command above.
3. Select the alignment from the dropdown list.
4. Select the section series from the dropdown list.
5. Choose a draw output option from the list.
6. Specify other options as desired.
7. Click OK to begin processing.

Notes:

• The section views must already exist with acceptable ranges for the SectionPoly option to work as it draws on section views.
• The 3dPolyline, Points, and FeatureLine options draw in plan view, so they do not require section views.
• The tolerance is 1/2 of the corridor width to consider points, or the distance from the sample line to a point to consider. If you use a distance too large, points may be picked up that don't represent the section at that sample.
• The classes field let you specify multiple classes to draw, like 2,6 is existing ground and buildings.
• Classes such as 6 (Buildings) create special situations since the results break (bldg top, gap, bldg top). To accommodate this, turn on the Break Gaps toggle and enter the minimum distance to consider a break (space between buildings). Also, there usually are no points on the ground level with a class like 6 to tie down the building. Turn on the Drop Ends toggle to draw segments from the building top points down to the surface.
