When trying to add only a section of "HC" or "GHC" Lumber in a truss with regular lumber, you may run into the error below. If that happen, it's because there is an order of operations in which the truss needs to be designed.
You will want to ensure that the change in lumber is done through the 'Engineer' icon after all changes have been made to the truss. You'll use the 'Change Member' icon inside of the Engineer Tab to achieve this.
- Change Member to your choice of HC/GHC lumber
- Run Analysis
- Plate Truss
- Save Truss
