extrude.set.set.un
Syntax
- void := extrude.set.set.un(sp,v_u,v_n)
The function only applies to 3D case (when 3D zones are generated from the Extruder).
Sets both the u-axis and n-axis (normal axis). They correspond to \(x\) and \(z\) directions in the extruder 2D coordinate system when the model is extruded into 3D.
Returns: void - void return
Arguments: sp - extrude set pointer
v_u - u-axis (3D vector)
v_n - n-axis (3D vector)
