I was hoping someone had the same problem and would be able to help me.
I am following your new tutorial with version 3.0 and no matter what I do I can never get my “profile” geometry to show up in Viz. I have tried making the profile a group, a component and neither and I can never ever get anything to show up at all. The syncing of the geometry is so simple there is now way anyone can really screw this up but alas, nothing shows up. I have also tried geometry sync with other types and complexities of geometry but still nothing! ARRRGGGGGAAAA
