Procedure

Quick Reference

To drop a perpendicular line from a 3D point down to the XY plane

1. Click Draw menu Line.At the Command prompt, enter line.
2. Use an object snap to specify a point on an object that is not on the XY plane of the UCS.

   This defines the first point of the line.

3. Enter .xy and then enter @ at the Of prompt.

   This operation extracts the X and Y coordinate values from the first point.

4. Enter 0 to specify the Z value.

   Using coordinate filters, the X and Y values extracted from the first point are combined with a new Z value (0) to finish the definition of the second point.

5. Press ENTER to end the command.
