I am creating a new construction from scratch in the Construction Manager. I have create several Materials by duplicating existing Materials that were close and setting my own thickness and conductivity. However, when I combine these materials into a Wall Assembly I receive the following error:
System.NullReferenceException: Object reference not set to an instance of an object.
