Parallel Line

Fix a point at specified parallel offset from two lines that have a known intersection point.

This function allows you to fix a point at specified parallel offset from two lines that have a known intersection point. A common use would be to calculate manhole positions a set distance from buildings or boundaries.

The intersecting lines are defined by entering a point that falls on the first line, followed by the intersection point and finally a point defining the second line. Thereafter, offsets are entered from both the first and second lines, and the intersection point is calculated.

The point calculated is assumed to be to the right of the three points in the order they were specified. In other words, to get the complementary situation of a point on the other side, specify the points in the reverse order.

Procedure

1. You are prompted to:

Parallel Intersection: Snap on start point

2. Click on the first terrain point.

3. You are prompted to:

Parallel Intersection: Snap on next point

4. Click on the second terrain point.

5.  You are prompted to:

Parallel Intersection: Snap on last point

6. Click on the last terrain point.

7. The Parallel Line Intersection options display.

8. Fill in the relevant data and click OK.

9. The Point Details display.

10. Fill in the relevant data and click OK.

11. The function continues in a cycle prompting for a start point.
