Description:

Constrains the picked point to lie on an arc.

Syntax:
public bool Constrain(
Arc arc
)
Parameters:
  • arc
  • Type: Arc
  • An arc to use as constraint.
Returns:
Type: bool
True if constraint could be applied.

Description:

Constrains the picked point to lie on a brep.

Syntax:
public bool Constrain(
Brep brep,
int wireDensity,
int faceIndex,
bool allowPickingPointOffObject
)
Parameters:
  • brep
  • Type: Brep
  • A brep to use as constraint.
  • wireDensity
  • Type: int
  • When wire_density<0, isocurve intersection snapping is turned off, when wire_density>=0, the value defines the isocurve density used for isocurve intersection snapping.
  • faceIndex
  • Type: int
  • When face_index <0, constrain to whole brep. When face_index >=0, constrain to individual face.
  • allowPickingPointOffObject
  • Type: bool
  • defines whether the point pick is allowed to happen off object. When false, a "no no" cursor is shown when the cursor is not on the object. When true, a normal point picking cursor is used and the marker is visible also when the cursor is not on the object.
Returns:
Type: bool
True if constraint could be applied.
