I am running into a weird face surface imagery and a lack or editable attributes when attempting to edit the bench leg posts and bench top components.
it looks like the bench top and bench post legs are contained in some uneditable or locked group or component structure.
I have attached a 2D export of a scene print showing the effected components and the edit drop options. I have not ever seen this. nor am I able to determine what I did or how to reverse the condition.
Probably still some residue in the Registry. I wouldn’t worry about it.
I’m not quite understanding what the issue is with the bench but you have a component that contains four leg components and the loose geometry for the top.
That’s a weird way to build it. The top ought to be a component in its own right and I would expect the other parts of the bench (stretchers, rails, drawers) to be included in the component as well.
For anyone else who comes along with a similar issue, this was the old bug in which Context menu items would be grayed out after a period of time. Installing the latest version of SketchUp 2021 ought to take care of it.
