Measures the distance between two points.Click on the start and then the end point of

the distance to be measured in the video image. The distance measured appears in the

status bar under result.

Measures the distance between two points as above but using vertical lines at the end of

the distance to be measured. This simplifies adjusting the measurements to straight edges.

Click on the start and then the end point of the distance to be measured in the video image.

The distance measured appears in the status bar under result.

Measures the length of the perpendicular from a point to a line.First click on the individual

point and then on the two end points of the line. The perpendicular from the point to the

line may lie outside the range covered by the two end points. The result is shown in the

results window on the status bar.

Measures the distance between two circles.Select three points on the first circle by clicking

on them with the mouse, then three points on the second circle. As soon as the first three

points have been clicked on, the first circle appears. The second circle is drawn as soon as

the sixth point has been clicked on. The distance between the centres of the two circles

is drawn. It also appears as a measured value in the result field.

Measures the distance between the centre of the circle and the perpendicular to a straight

line.Select three points on the circle by clicking on them with the mouse and then similarly

select two points for the line. As soon as the first three points have been clicked on the

circle appears. When the fifth point has been clicked on the line is drawn and also the

vertical distance from the centre of the circle to the line (or its extension). For a line width

of 1 point the line is shown dashed, for all other line widths it is shown as a solid line.

The distance appears in the result field in the status bar.

Chain dimension continuously measures a series of adjoining lines.The start point of the first line

is clicked on first, then other points. The length of the current last line is shown in the result field.

The sum of all the lines is then displayed if the object has been transferred to the table. 

The table shows the lengths of all segments and the total.
