Select the 2D element or element face to project extrude and set the projection target (target surface) and direction. The element size can be directly entered or defined by the number of divisions on the distance to the projection. The original element (2D element) used in extrude can be deleted/moved/copied. For move, the used element is moved to the end of the extruded element.

Project Target
Select an existing surface of a geometry shape or an element boundary surface as the project target (target surface). Or, select 3 arbitrary points that pass the target surface using the [Three points Plane] function.
Projection Direction
Set the projection direction using the axis direction on the GCS or the direction of an arbitrary vector that connects the start and end points. Use the [Shortest Path Line] to automatically set the shortest distance direction between the node and projection target (target surface) in the normal direction.
