Extrude

In addition to the basic shapes like a Block or Cylinder the Advanced mode also supports extrude operations. The extrude operation generates a shape by extruding a 2D profile along the Z-axis. To create an extrude select the block from the objects menu and add three or more points from the transformations menu. Then enter the height of the extrusion. The profile below is created by subtracting an array of cylinders from an extrusion.
