Reinforced Concrete Design Modules
Issue: Several dialogs in the Reinforced Concrete Design modules are not working. This issue occurs when you have Robot Structural Analysis 2022 and Revit 2022 installed on the same machine, and you uninstall Revit 2022. The issue results from some common components having been unregistered. Solution: Reinstall Robot Structural Analysis 2022 or contact Customer Support for further assistance.
