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,including the picked points or the hierarchy level used to calculate a minimum objectdistance.A special measurement for judging gaps is a line-to-object measurement, whichcan be used if the original model already contains according line geometry. For creatinga line-to-object measurement, the first object has to be a line geometry, whilethe second may be either any other geometry. The measurement then will createsample points along the line and for each point the minimum distance to the secondobject will be calculated. The result will be displayed in the render window using aspecial visualization of all distances: The distances will be displayed as lines both inthe 3D scene and in a 2D diagram at the lower left corner of the render window.Hovering with the mouse over the diagram highlights a particular distance in the 3Dview and shows its exact value on top 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 isavailable. The gap measurement is calculated along the line segment between twopicked points on two distinct objects. The viewer will try to find multiple minimumdistances between the two objects, where each distance calculation is restricted tobe on a plane perpendicular to the line segment. The result will be displayed in therender window using a special visualization of all distances, as for line-to-object measurements.Note that measurements starting and/or ending on objects identify these objectsby their name. Ensure that your measured objects have a unique name within thescenegraph structure when saving and loading measurements.» Right click context menu» Add Point to Point Measurement: Calculates the distance between two explic-153
