   • Dragging a blue arrow moves the point vertically.
   • Dragging a red square (shape handle) moves the point horizontally.
8. Click the text control to enter a precise height value for the selected point or edge.

   The value of the height represents the offset from the original top face of the toposolid.

9. Click (Modify). To complete the Toposolid.
