Calculated Point

Often, the most accurate way to calculate a point is to calculate it from other features. For
example, Calculated Points can be calculated based on the intersection of two lines, a line and
a circle, or midway between two points.

A Calculated Point tool is also used to place a fixed point in the field of view. A fixed point could
be used if you want to make all your measurements from a known reference point.

The Calculated Point tool calculates a point based on the calculation mode. Possible modes
are:

l

Midpoint (midpoint between two points)

l

Point and a line (closet point on the line to another point)

l

Point and an arc (closest point on the arc to another point)

l

Fixed point

l

A line and an arc (Line/Arc intersection)

l

Two lines (Line-line intersection)

l

Two arcs (Arc-arc intersection)

To create a Calculated Point tool, right-click in the Tree structure, then select:
