Chimneys by default are 12’ tall, but you can change this before or after you insert the chimney to create the correct height needed for your house. By default, the chimney in the catalog has a brick base and concrete cap. You can edit the appearance of the chimney to match the exterior of your home if you are inserting the chimney on the outside.
To insert a chimney:
Select Insert
> Interiors > HVAC Elements, or click the HVAC Elements button
on the Interiors toolbar.
In the catalog, select the Ventilation category, then select the Chimney element.
Position the chimney where you want it, then click to insert it.
Right-click and select Finish.
