# Measurement Functions

You can access DICAM's measurement functions at any time via the assistance menu.\
You open the assistance menu by selecting the Measure button in a dialog box. If no dialog box is open, you can also open the assistance menu by pressing the middle mouse button or by holding the Shift key and pressing the right mouse button. For the middle button of a three-button mouse to respond correctly, you must also configure that button as the middle button in your mouse configuration software.

## Global - Local

We distinguish between global and local measurement functions. When you measure globally, the coordinates, distances and angles refer to the current coordinate system. When you use the local measurement functions, the measurement results refer to the body coordinate system of the selected rod.

## Measurement results

For the two measurement functions Point to Point and Line, the measurement results are displayed in an extensive dialog box.

The top area of the dialog box shows the X, Y and Z coordinates of the first and second points. Below that, the absolute distance between the two points is given. In the area below that, the distance between the two points parallel to the X, Y and Z axes of the current coordinate system is displayed. The next three values refer to the projection of the two points onto the three standard planes. These values indicate how far apart the projections of the two points are when measured in the respective plane. The remaining six values indicate angles. The first three values give the angle between the projection of the line connecting the two points and an axis of the coordinate system. The last three values give the angle that exists between the line connecting the two points and a standard plane.

## Measure from point to point

With this function you determine distances and angles between two points. Points can be auxiliary points or endpoints of auxiliary lines and body edges.

## Measure line length

With this function you determine the values of an auxiliary line or a body edge. This function calculates all values that are also determined by the Point to Point measurement function.

## Measure parallel lines

With this function you determine the perpendicular distance between two parallel lines. The position of the lines in space and the line length are irrelevant. This function determines only the distance between the two lines. No additional values are calculated.

## Measure point to line

With this function you measure the perpendicular distance from a point to an auxiliary line or a body edge. This function determines only the distance between point and line. No additional values are calculated.

## Angle between two planes

With this function you determine the angle between two arbitrary planes. You can define each of the two planes using two lines or three points.

## Angle between line and plane

With this function you determine the angle between an auxiliary line or a body edge and an arbitrary plane. You define the plane using two lines or three points. The line can be selected directly as a line or determined by two points.

## Angle between two lines

With this function you measure the angle (W) between the projections (P) of two lines (L1, L2) onto a plane (E).
