Line of Sight

Generate a set of points at a given height at the nearest intersection with the model at that height.

This function will, given a centre point and an eye-level height, generate a set of points at the given height, either at the nearest intersection with the model at that height or at the specified sight distance should no ground intersection occur within that distance.

In order to generate the line-of-sight points, a cross-section is taken every three degrees around the centre point and the intersection between the line of sight and ground model calculated.

Procedure

1. You are prompted to:

Indicate eye location

2. Click on a position in the Design Centre window and the Line of Sight Details display.

3. Fill in the relevant data and click OK.

4. The line of sight from the specified point is displayed in the Design Centre window.
