     2. Do either of the following:
        • Select 2D, and click the wall in the drawing, if the wall is in the open drawing-model pair.
        • Select 3D, and click the wall in the model.
   • Click the height in the model in the following way:
     1. Click the Digitize button. The model window becomes active.
