I cannot select assemblies nor can I highlight a full assembly (Main Mark). I have opened several models in TC and this option does not seem to work. I have toggled "Object Selection Mode" both on and off and still cannot select or highlight assemblies. This was never an issue with Tekla BIMsight. Highlighting assemblies is an incredibly useful tool that allows me to review connections. So my questions are:
Is there an option or button I am missing?
Is this ability a function of how the model is created/saved originally?
