Quick tip should you override any of the surface materials of a conceptual mass face using Conceptual Energy Analysis…
When you have Conceptual Mass > Show Mass Surface Types set active, you can TAB select individual faces and override the Graphical Appearance; which can use any of the available materials in the project:
Should this occur, there are two options to restore it back to the default graphical appearance:
1. Highlight the face > Identity Data > Subcategory > toggle the type to another subcategory and then back to the original.
2. Analyze > Energy Settings > Energy Model > un-check Create Energy Model > OK > then re-check Create Energy Model.
**Please keep in mind approach #2 should only be used if there are no additional overrides throughout the model, as all overrides will be reset**
