GMOperatorsInterfaces Interface CATICGMTopExtrapolWireOpe
Usage: an implementation of this interface is supplied and you must use it as is. You should not reimplement it.
interface CATICGMTopExtrapolWireOpe
Class defining the topological operator to extrapol a wire.
The operator produces a wire topology result of the extrapolation of the input wire.
The user can customize the extrapolation with the Setxxx methods to
- define the type of continuity : tangency or curvature.
- define the extremity from which the extrapolation starts.
- define the length of extrapolation or the body to reach.
When no support is defined,
the extrapolation in curvature "up to" is only possible if the body to reach is a wire and a plane;
the extrapolation in curvature of a given length is the extrapolated wire relimited by the plane
created at the given length from the chosen extremity.
When a support is defined,
the extrapolation in curvature is only possible on the faces with same geometry.
This operator follows the general scheme of the topological operators:
- Create the operator with the CATCGMCreateTopExtrapolWireOpe global function.
- Set the extrapolation parameters: continuity, extremity, length...
- Run with the Run method.
- Get the result body by the GetResult method.
- Release the operator with the Release method after use.
Method Index
- o
GetResult()
- Returns the result of this operator.
- o
GetResult(CATCGMJournalList*)
- Returns the pointer to the resulting body.
- o
Run()
- Runs this operator.
- o
SetContinuityType(int)
- Defines the type of continuity.
- o
SetExtrapolLimit(CATVertex*,double)
- Defines the extremity from which the extrapolation must start and the length of the extrapolation.
- o
SetExtrapolLimit(CATVertex*,CATBody*)
- Defines the extremity from which extrapolation must start and the body to reach.
- o
SetNoSimplifOnLine()
- By default the result of the extrapolation of a line in tangency
when no support is defined gives a body which only contains one edge.
Methods
o GetResult
| public virtual GetResult( | ) |
-
Returns the result of this operator.
- Returns:
- The pointer to the created body.
o GetResult
| public virtual GetResult( | | iJourn) |
-
Returns the pointer to the resulting body.
The pointer to the journal of the operation.
- Parameters:
-
- iJourn
- The pointer to the journal to fill.
- Returns:
- The pointer to the resulting body.
o Run
-
Runs this operator. Returns 0 if the operation completes properly.
o SetContinuityType
| public virtual SetContinuityType( | | type) |
-
Defines the type of continuity.
- Parameters:
-
- type
- 1 for tangency continuity
2 for curvature continuity.
o SetExtrapolLimit
| public virtual SetExtrapolLimit( | | iVertex, |
| | ilength) |
-
Defines the extremity from which the extrapolation must start and the length of the extrapolation.
- Parameters:
-
- iVertex
- The vertex must be one of the two extremities of the wire to extrapolate.
The extrapolation is only possible from one vertex.
- ilength
- The length must be a positive value.
o SetExtrapolLimit
| public virtual SetExtrapolLimit( | | iVertex, |
| | iLimBody) |
-
Defines the extremity from which extrapolation must start and the body to reach.
- Parameters:
-
- iVertex
- The vertex must be one of the two extremities of the wire to extrapolate.
The extrapolation is only possible from one vertex.
- iLimBody
- The body to reach can be:
- a wire (laid on the same support than the body to extrapol)
- a shell (must be plane when extrapolation in curvature mode and no support defined).
o SetNoSimplifOnLine
| public virtual SetNoSimplifOnLine( | ) |
-
By default the result of the extrapolation of a line in tangency
when no support is defined gives a body which only contains one edge.
The intermediate vertex has been cleaned.
To avoid this behaviour and keep the vertex use the following option.
