About Filter
positions option: This option can be used to simplify the swept volume computation when the replay object contains many positions or when you know what precision level you need to obtain. The "filter precision" defines the maximum distance allowed between the simplified trajectory and the initial one (= discretization precision) 

1 Filtering swept volume positions 

The following example aims at illustrating the impact of the filter positions option on the final result  
Case 1: the Filter positions option is not checked:  
Case 2: the Filter positions option is checked Filtering precision = 5mm 



Case 3: the Filter positions option is
checked Filtering precision = 10mm 



2 Relative swept volume


About Relative swept volume: You can compute the swept volume of a moving part in the system axis of another moving part. You can use this option when you need to analyze the swept volume of a product versus another product (moving or not) Example: two moving parts: circle and square With the basic computation of the swept volumes, the clash analysis is not relevant: the swept volumes clash but two objects may not be in the same clash area at the same time. 



If you use the relative swept
volume option and select the circle as the reference product, you can
compute the square swept volume in the circle system axis. The result can now be relevant for clash analysis.
