Defining a custom pair of reference planes whose upper plane is inclined

1. Click Match.

   The Custom Planes dialog box closes.

2. Click the first definition point and enter a height for this point in the dialog line.
3. Click the second definition point and enter a height for this point in the dialog line.
4. To finish entering the custom reference plane, do the following:
   • In the dialog line, enter the angle of inclination and click to indicate the area of upward inclination
   • Click the third definition point and enter a height for this point in the dialog line.
5. Enter a polygon (as construction points) to define the outline of the pair of reference planes as you would a polyline.

   Architectural elements associated with and delimited by them (in plan) will automatically adjust to the new heights imposed by the planes. (This does not apply to elements whose heights were defined as absolute values.)
