I made some shots with the scenes in sketchup, used the section planes to cut the house. I had to close my work and after reopening my house model closed back up . I can see the saved scenes on the edge of my page, (please see screenshot) but my house is closed and I can’t see the cuts and the scenes. How can I reopen the house and see my scenes with animation without deleting the whole thing and starting over?
Only a guess without seeing your SketchUp file. After turning on the section cuts you didn’t update the style associated with the scenes or update the scenes to show the sections. You can expose the section cuts and make them active again, then update the scenes making sure you also update the style.
BTW, your profile says you are using the free web version of SketchUp but you show SketchUp Pro. Please correct your forum profile.
