Some of the pages of my Layout document have lost their relationship to the Sketchup drawing they are based on. I can no longer edit the drawing. I cannot select the image anymore. I can still go to Sketchup and open the file, but the changes will not be reflected in the Layout page. This only happens some of the time. Any thoughts?
Have you tried to restore the relationship in the Layout preferences?
Do you mean by resetting the Auto Render?
If you can see the SketchUp model/viewport but can not select it, check to see if the viewport as been placed on a Layer that is locked.
