How to create layouts for sketchup shop

Just purchased Sketchup web Shop.

Q: How can I adjust layouts, add title block, add text in the title block, for printing 2D

What do you mean by “adjust layouts”? You could add screeen text for title block information using the Text tool and you can create scenes to show your model as you need. Use tags to control visibility of the components/groups in your model for each scene. Once you’ve got the scenes set up use the Print feature to print each scene as a page.
