Capturing measuring points

When you measure an object, the existing geometries are determined based on
features. To determine a feature, you need to capture measuring points for the
feature.
A measuring point is a point in the coordinate system whose position is defined
by the coordinates. Based on the positions of the captured measuring points
(point cloud) in the coordinate system, the product can determine and evaluate the
feature. The product optionally provides various ways to capture measuring points:
Without a sensor, e.g. by using crosshairs on the measuring microscope or
profile projector
With a sensor, e.g. in the form of a camera on the measuring machine
10.3.1

Capturing measuring points without a sensor

If measuring points are captured without using a sensor, the operator on the
connected measuring machine (e.g. measuring microscope, profile projector) must
be able to move to the desired position on the measured object, e.g. by using
crosshairs. On reaching this position, the measuring point acquisition is initiated
either manually by the operator or automatically by the product, depending on the
configuration.
For the measuring point, the product captures the current axis positions that are
displayed in the workspace or position preview. The coordinates of this measuring
point thus result from the current position of the measuring plate. Based on the
captured measuring points, the product determines the feature according to the
selected geometry and displays it in the feature list in the Inspector.
The number of measuring points that need to be captured for a feature depends on
the configuration of the selected geometry.
The procedure for capturing measuring points without a sensor is
basically the same for all geometries and is described below using the
"Circle" geometry as an example.
