Floor and Ceiling materials used to be specified on the Materials tab in Chief Architect X2 and earlier versions, and I can't find where to change these values in newer programs. How can I do this?
Starting in Chief Architect X3, you now have more control over Floor and Ceiling structure, so the finish for these is also set on the Structure panel of your Room Specification dialog.
Changing your floor or ceiling finish
Using the Select Objects tool, click inside of the room where you want to change the flooring or ceiling material.
Next, click on the Open Object edit tool to display the Room Specification dialog.
On the Structurepanel, click on the Edit button next to the 'Ceiling Finish' or 'Floor Finish' categories to display the Finish Definition dialog, where you can specify the thickness and materials for your finish.
