Positioning and Comparison Rules - Comparison method tab

Used to set part comparison method and limit tolerance values.
Setting Description
Calculation Method
  • Geometry Check ? At recognition via geometry, all outer edges of a component part are determined and individually compared with each other. In the following, you will find a description of the tolerances specifying that two parts are recognized as identical.

    Here, you specify the tolerances for recognition of identical parts via geometry. You can positively exclude that e. g. rounding errors in the case of bevel cuts or notches lead to different parts.

  • Volume Check ? A second method to recognize equal parts is the real volume comparison. Here, you carry out a detection of identical parts based on the volume of the component part.

    The tolerances can be set for groups and single parts as relative value to the compared volume (e.g. 0.1 percent for component parts and 0.2 percent for groups). Enables the Max Part Difference and Max Group Difference settings.

Minimum Line Length Lines up to the specified length are not considered for a comparison.
Length Tolerance Length deviations of two lines up to the specified length are not considered for a comparison.
Drill Hole Tolerance Deviations of the drill hole axes up to the specified length are not considered for a comparison.
Weight Tolerance Differences in weight between two component parts are ignored up to the indicated value.
Max Part Difference Enabled for Volume Check method. Sets the maximum difference in % up to which the elements are treated as identical.
Max Group Difference Enabled for Volume Check method. Sets the maximum difference in % up to which the groups are treated as identical.
Description Distribution These settings are used for naming the connections (positioned logical links).
  • Continues Numbers ? The connections are numbered consecutively.
  • PosNum+PosNum ? The name is built using a combination of the position numbers of the connecting and supporting shape.
  • PosNum+Index ? The name is built using the position number of the connecting shape and a continuous index.

For more detailed information about connections, please refer to the main chapter of detailing.
