- At the prompt for a point, enter a coordinate filter (.x, .y, .z, .xy, .xz, or .yz). For example, enter .x to specify the X value first.  
- To extract the specified coordinate values, specify a point. For example, if you previously entered .x, the X value is extracted from this point.  
- At the prompt for the remaining coordinates, do one of the following: - Extract the remaining coordinate values by specifying a point. 
- Enter another coordinate filter. 
 For example, if you previously entered .x, specify a second point to extract the Y and Z coordinates simultaneously, or enter .y or .z to specify Y and Z values separately.  The new point location combines the coordinate values extracted from the previously specified points.  
Note: Instead of specifying a point, you can enter a numeric value at any coordinate filter prompt.
