6.3 Interactionof the measurement list. You will be prompted to select the first point (or object)followed by the second point (or object), then the according distance will be calculated.After the measurement has been created, some parameters can be adjusted, includingthe picked points or the hierarchy level used to calculate a minimum object distance.A special measurement for judging gaps is a line-to-object measurement, which canbe used if the original model already contains according line geometry. For creating aline-to-object measurement, the first object has to be a line geometry, while the secondmay be either any other geometry. The measurement then will create sample pointsalong the line and for each point the minimum distance to the second object will be calculated.The result will be displayed in the render window using a special visualizationof all distances: The distances will be displayed as lines both in the 3D scene and in a 2Ddiagram at the lower left corner of the render window. Hovering with the mouse overthe diagram highlights a particular distance in the 3D view and shows its exact value ontop of the diagram.The most complex measurement is the gap measurement which is a useful substituteof the line-object-measurement in the case no appropriate line geometry is available.The gap measurement is calculated along the line segment between two picked pointson two distinct objects. The viewer will try to find multiple minimum distances betweenthe two objects, where each distance calculation is restricted to be on a planeperpendicular to the line segment. The result will be displayed in the render windowusing a special visualization of all distances, as for line-to-object measurements.Note that measurements starting and/or ending on objects identify these objects by their name.Ensure that your measured objects have a unique name within the scenegraph structure whensaving and loading measurements.» Right click context menu» Add Point to Point Measurement: Calculates the distance between two explicitlypicked points.» Add Point to Object Measurement: Calculates the minimum distance between159
