EDIT: Never mind, My idiocy. The reference model had been changed and not updated in Layout and I was not aware. Any activity modifying Scene 8 rerenders to the true new scene 8. I will go make coffee now.
I guess I missed my coffee this morning. I have viewports corresponding to in model scenes. Worked for the other pages/viewports but when I get to scene 8 which is an Ortho Plan when I change the scale it switches to a front elevation. I must be overlooking something obvious here?
Thanks. I was being thick, I went back to check the Su file to see and the scenes have been changed, but the link not updated in Layout. So the old Scene 8 was still showing in that viewport but any attempt to modify it re-linked to the true scene 8 in the model. I’ll leave all this up for others as a cautionary tale.
