Click on the wall you want to change the thickness of, whether straight or curved.
The properties panel for the selected wall will open on the left side.
In the properties panel, find the "Thickness/Composites" dropdown arrow.
Click on this dropdown arrow to access the thickness options.
Within the dropdown, you will see a "Thickness Source" toggle button with two options: "From Composite" and "Custom Value."
To select a thickness from the default available options, click on "From Composite." Then, choose the desired thickness from the drop-down menu that appears.
To specify a custom thickness that is not part of the default options, click on "Custom Value." Enter the desired thickness value into the "Thickness" field.
Once you've made your selection or entered the custom thickness value, the wall's thickness will be updated accordingly.
These steps allow you to easily adjust the height and thickness of walls in your Infurnia design to meet your project requirements.
