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:
New > Vision > Tool > Calculated Point
