GMOperatorsInterfaces Global Function CATCGMCreateTopSplitShell

Constructs an operator that splits a CATShell domain by a CATShell or a CATWire domain.
The body to split and the cutting body must only contain one shell domain and one (shell or wire) domain respectively.
Orientation: The orientation of the resulting domain is the orientation of the domain to be split.
Journal:

• The faces that are kept and not cut are written as CATCGMJournal::Keep
• The faces that are cut are written as CATCGMJournal::Subdivision
• The new edges are written as CATCGMJournal::Creation
• The faces that are neither cut, nor kept, are written as CATCGMJournal::Deletion

Parameters:

iFactory

A pointer to the factory of the resulting body.

iData

A pointer to the topological data.

iBodyToCut

A pointer to the body to cut. It must only contain one shell domain.

iCuttingBody

A pointer to the cutting body. It must only contain one (wire or shell) domain

iSelectMode

The selection of the resulting parts. Do not use BOTH_SIDES for a split operation.

• Shell cut by a shell:

  POSITIVE_POSITIVE_SIDE or POSITIVE_NEGATIVE_SIDE

  The partitions to keep are pointed to by the orientation of the splitting shell.

  NEGATIVE_POSITIVE_SIDE or NEGATIVE_NEGATIVE_SIDE

  The partitions to remove are pointed to by the orientation of the splitting shell.

  BOTH_SIDES

  Do not use this value.

• Shell cut by a wire:

  POSITIVE_POSITIVE_SIDE or POSITIVE_NEGATIVE_SIDE

  When standing along the shell orientation and watching in the direction of the wire leads to have the kept partitions to the left.

  NEGATIVE_POSITIVE_SIDE or NEGATIVE_NEGATIVE_SIDE

  When standing along the shell orientation and watching in the direction of the wire leads to have the kept partitions to the right.

  BOTH_SIDES

  Do not use this value.

iExtrapolMode

The extrapolation mode to specify when the cutting body does not cut right along the body to cut.

• NO_EXTRAPOLATION: No extrapolation is performed. The operator cannot find a solution if the cutting body does not cut right along the body to cut.
• TANGENT_DIRECTION: If the cutting body does not cut right along the body to cut, the extrapolation is made tangentially to the scar at the last computed point.

Returns:

[out, IUnknown#Release] The pointer to the created operator. To be released with the Release method afer use.
