Help - ceiling thickness

[David J. Potter]

The settings seem to keep changing themselves so that this combination is impossible.

What you are seeing is the software following its "Default Settings" (Edit - Default Settings - Floor).

Make those settings in "Edit - Default Settings - Floor" first and then in local roof dialog boxes as you create them, they will be preset to what you have programmed "Default Settings" to be.

I think it might be because the Ceiling structure and floor structure settings cannot be changed, and these may reflect the thickness of the gap between ceiling and floor above.

Lamina is correct in that in Suite floor platform thickness for the second and third floors are preset but the foundation can be programmed by you and you can, when Defaults are correctly set first, control ceiling heights.

It is part of learning how the software works and does not work.
