I use 3d solids for foundations in my models as I have found they are easier to manipulate than concrete objects.  The problem I am having is that the solids do not show on camera views.  What is the model role and presentation setting for 3D solids?  I have tried multiple attempts using Plant 3D model roles to no avail.  Is this a glitch in AS2019 that will be ironed out soon? (She said hopefully!)
