Solid Models in Sketchup
What is it?In order to 3D print your models, they must be solid, watertight , manifold. The model must not have any extra lines or faces. If you make your object into a group or component, Sketchup will let you know if it's solid by opening the Entity Info dialog box. Click on your model and open Window>Entity Info.
