## LinearExtrusion class

Linear extrusion takes a 2D shape as input and extends the shape in the 3rd dimension.

| [parent_nodes](/3d/python-net/aspose.threed.entities/linearextrusion/parent_nodes) | Gets all parent nodes, an entity can be attached to multiple parent nodes for geometry instancing |
| [excluded](/3d/python-net/aspose.threed.entities/linearextrusion/excluded) | Gets or sets whether to exclude this entity during exporting. |
| [parent_node](/3d/python-net/aspose.threed.entities/linearextrusion/parent_node) | Gets or sets the first parent node, if set the first parent node, this entity will be detached from other parent nodes. |
| [shape](/3d/python-net/aspose.threed.entities/linearextrusion/shape) | The base shape to be extruded. |
| [direction](/3d/python-net/aspose.threed.entities/linearextrusion/direction) | The direction of extrusion, default value is (0, 0, 1) |
| [height](/3d/python-net/aspose.threed.entities/linearextrusion/height) | The height of the extruded geometry, default value is 1.0 |
| [slices](/3d/python-net/aspose.threed.entities/linearextrusion/slices) | The slices of the twisted extruded geometry, default value is 1. |
| [center](/3d/python-net/aspose.threed.entities/linearextrusion/center) | If this value is false, the linear extrusion Z range is from 0 to height, otherwise the range is from -height/2 to height/2. |
| [twist_offset](/3d/python-net/aspose.threed.entities/linearextrusion/twist_offset) | The offset that used in twisting, default value is (0, 0, 0). |
| [twist](/3d/python-net/aspose.threed.entities/linearextrusion/twist) | The number of degrees of through which the shape is extruded. |
