This method allows you to extrude elements by rotating them about an axis or vector.
- Axis
specifies the axis or a vector to indicate the direction of rotation, or the axis to which the normal of the element is aligned.
- Center of Rotation
allows you to select the origin or another point as the center of rotation.
- Translate
If enabled, the extruded mesh will include both translational and rotational extrusion.
- Spacing
The fixed height of each extruded layer.
- Direction
Choose the Method using the radio buttons.
- Explicit Vector
specifies the X Y Z vector components of the vector, based on the active coordinate system. For example, "0 0 1" will extrude in the Z direction.
- Vector by points
Define a vector by selecting two points. Elements will be moved in the direction of the defined vector.
- Angle per layer
Angle of each layer of rotation.
- Number of Layers
specifies the number of layers of the existing mesh for extrusion.
- Merge Degenerated Elements
if enabled will merge all nodes on or near the axis of rotation within the defined Degeneration tolerance (the default is 0.00001). For example, degenerate hexas with one degenerate face on the axis (two sets of coincident nodes) will become prisms with one edge on the axis (two nodes).
- Degeneration tolerance
If Merge Degenerated Elements is enabled, then this tolerance can be specified (default is 0.00001). This tolerance is used to find equal nodes in degenerated elements by using it as a ratio between the current node distance and the maximum distance of all nodes in the element.
