<Parameters2> Array

Structured array containing these parameters in order:

  • <NAME:Setting Contents>
  • <IsFactorBased>
  • <SnapTol>
  • <AlignTol>
  • <RemoveDanglingVias>

<NAME:Setting Contents>

 String Required first parameter which must have the specified value (i.e., "Setting Contents").

<IsFactorBased>

 Boolean True selected via groups are snapped by a maximum area equal to the tolerance (i.e., <Snaptol> and <AlignTol>) times the surface area of the via group.
False selected via groups are snapped by a maximum distance of the tolerance.

<SnapTol>

 Integer Vias at or within this tolerance are snapped.

<AlignTol>

 Integer Vias at or within this tolerance are aligned.

<RemoveDanglingVias>

 Boolean True removes vias from selection that have no connectivity or have connectivity only to a single layer.
False deactivates this check.
Return Value

None.
