No matter what I include/exclude using the "Create WorksManager Design", when opening in Siteworks I will get the following error "The VCL design file contains data that is not supported by Siteworks". The surface dropdown in Siteworks always has "(No Surface Needed)" and does not have any other options even though a surface was selected/added from TBC. I have tried just having one surface with nothing else and it still does not work. I can create a TTM out of the same surface and that can be opened just fine from Siteworks. Siteworks is running version 1.20.20100. TBC Version 5.21. Not sure what is going on.
