Chimneys

Select the fireplace in a 3D view.

Hold down the Ctrl key, click on the topmost edit handle and drag the chimney up through all the floors and the roof until it is to the desired height. The Ctrl key prevents the chimney from stopping when it reaches the ceiling height.

When the chimney is approximately the correct height, select the fireplace, click the Open Object

edit button, and type in the exact height.

Chimney Chases & Caps

Place a soffit in position over the chimney chase, resize it to match, then extend the soffit using the same method as extending the masonry fireplace in the 3D view.

If the chimney chase is drawn with walls on the exterior of the house, you can continue the chase using walls on the floors above. Align walls with the chase on each subsequent floor. The chimney chase "room" on the uppermost floor should have a much higher ceiling defined in the Room Specification dialog. It should also be set to have no roof by unchecking Roof over this room in the Structure tab of the Room Specification dialog. Rebuild floors and ceilings and the roof, if needed.

Chimney caps can be made using soffits, polyline solids, or other primitive objects.
