Description

Selectively removes a layer array constraint value from a specific constraint group or from all constraint groups.

Arguments

-all

Removes the constraint from all constraint groups.

-allMembers [true|false]

  

When set true, removes all members of the constraint from the given group (-group) or from all groups (-all). This is particularly useful for removing all members from an AND or OR group.

Default: (false) Removes only the first member of the constraint.

-constraint s_constraintName

  

Specifies the name of the constraint to remove.

-group s_groupName

Specifies the group from which to remove the constraint.

-hardness {hard | soft | preferred | default}

  

Removes the constraint value for the given enforcement setting. If this was the last set value for the constraint, the constraint is removed from the constraint group(s).

  

default

Removes the first value found: hard or soft.

  

hard

Removes the hard value.

  

preferred

Removes the first value found: soft or hard.

  

soft

Removes the soft value.

-layer_array {s_layerName…}

Specifies the layers associated with the constraint.

-model {OXIDE1 | OXIDE2 | OXIDE3 | OXIDE4}

Removes the constraint value for the given antenna model. If this was the last set value for the constraint, the constraint is removed from the constraint group(s).

-verbose [true|false]

When set to true, the constraint name(s) and group(s) are output.
