This method allows you to extrude elements in a linear direction defined by a vector.
- 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.
- Number of Layers
specifies the number of layers to be extruded. By default it extrudes one layer.
- Spacing type
determines the height of each layer. A Fixed spacing will make each layer that same height. Spacing can also be defined by a Function of the layer variable, using Tcl syntax. See Tclers Wiki for descriptions of Tcl syntax for different mathematical expressions.
For example, Spacing can be defined as 0.3*layer. Then the mesh will be extruded along the defined vector, with the first layer height as 0.3, the second layer height as 0.6, etc.
Spacing can also be defined by a function of geometric growth as follows:
height1 * pow (ratio1, layer-1),
where height1 is the height of the first layer, pow is the expression for an exponent, and ratio1 is the growth factor.
