Imprint all specified geometries onto specified faces of the body.

Parameters:
faces: List[Face]

List of faces to imprint the curves of the sketch onto.

sketch: Sketch

All curves to imprint on the faces.

Returns:
Tuple[List[Edge], List[Face]]

All impacted edges and faces from the imprint operation.

Body.project_curves(direction: ansys.geometry.core.math.vector.UnitVector3D, sketch: ansys.geometry.core.sketch.sketch.Sketch, closest_face: bool, only_one_curve: beartype.typing.Optional[bool] = False) beartype.typing.List[ansys.geometry.core.designer.face.Face]#

Project all specified geometries onto the body.

Parameters:
direction: UnitVector3D

Direction of the projection.

sketch: Sketch

All curves to project on the body.

closest_face: bool

Whether to target the closest face with the projection.

only_one_curve: bool, default: False

Whether to project only one curve of the entire sketch. When True, only one curve is projected.

Returns:
List[Face]

All faces from the project curves operation.

Notes

The only_one_curve parameter allows you to optimize the server call because projecting curves is an expensive operation. This reduces the workload on the server side.

Body.imprint_projected_curves(direction: ansys.geometry.core.math.vector.UnitVector3D, sketch: ansys.geometry.core.sketch.sketch.Sketch, closest_face: bool, only_one_curve: beartype.typing.Optional[bool] = False) beartype.typing.List[ansys.geometry.core.designer.face.Face]#

Project and imprint specified geometries onto the body.

This method combines the project_curves() and imprint_curves() method into one method. It has higher performance than calling them back-to-back when dealing with many curves. Because it is a specialized function, this method only returns the faces (and not the edges) from the imprint operation.

Parameters:
direction: UnitVector3D

Direction of the projection.

sketch: Sketch

All curves to project on the body.

closest_face: bool

Whether to target the closest face with the projection.

only_one_curve: bool, default: False

Whether to project only one curve of the entire sketch. When True, only one curve is projected.

Returns:
List[Face]

All imprinted faces from the operation.

Notes

The only_one_curve parameter allows you to optimize the server call because projecting curves is an expensive operation. This reduces the workload on the server side.
