Select a ceiling plane and click the Open Object 
edit button to open the Ceiling Plane Specification dialog.
The Ceiling Plane Specification dialog is similar to the Roof Plane Specification dialog. See "Roof Plane Specification Dialog".
There are four values that define the height, or 3D orientation of a ceiling plane: Bottom at Ridge, Inside Bottom, Outside Bottom and Pitch. These values are interrelated. Changing one changes the others. Select one radio button to the right to lock that value. Each of these dimensions is measured from the first floor elevation of 0' -0". Changing these values does not affect the 2D representation of the ceiling plane.
Bottom at ridge - Set the highest point on the underside of the ceiling plane.
Inside Bottom - Set the height of the ceiling plane underside at the inside surface of the wall main layer. If the bottom of the plane does not rest on a wall, this is the underside height at the lowest point on the ceiling plane.
Outside Bottom - This is available only if the ceiling plane was drawn over a wall. This value is of the height the ceiling rafter lower edge would have at the outer main layer of the wall if it were not clipped. This value plus Clip End should be within 1/16" of the Top of Plate value.
Pitch - Change the pitch for the selected ceiling plane. For a conversion to degrees, see "Roof Pitches in Degrees".
Pitch in degrees - Select the check box to display the pitch value in degrees.
Check Curved Roof to curve the selected ceiling plane(s).
A flat ceiling plane oriented horizontally has an angle of zero at both the ridge and the eave. It also has a radius of zero. You can enter the Angle at eave, the Angle at ridge, or the Radius to roof surface and press the Tab key to update the other values. All three values are interrelated and dynamic. Changing one changes the others.
Rafter Depth - Specify the rafter depth for the selected ceiling plane.
Vertical Rafter Depth - This is defined by measuring a plumb line across the rafter. The degree of pitch affects this value; the greater the pitch, the greater the vertical rafter depth.
Top of Plate - This is shown for reference. It is defined by the ceiling height for the room.
Overhang from inside bottom - This is available only when the ceiling plane was created over a wall. It is the horizontal distance from the baseline to the inside main layer surface. Typically this is the thickness of the main wall layer.
Clip End - This shows the amount the ceiling rafter must be clipped at its lower end to rest on the wall top plate. It is available only for ceiling planes drawn over a wall.
