Make customized block and component families of outdoor equipment and furniture catalog for use in SketchUp design software. SketchUp components? A SketchUp component is a named collection of geometry that can exist at multiple locations within the model causing each instance to repeat all others. In SketchUp, the process of modeling complex items requires internal order. This order can be attained using Groups or Components. By definition, a Group is a single instance of a collection of geometry. SketchUp components allow users to reuse objects that they may commonly work with on several different occasions and instances. In simulation a change to one instance changes all other instances. For the reason that every building and or building model has at least one door and window, use of SketchUp components allows SketchUp modeling to be more seamless and not mundane during implementation. Because instead of re-modeling these commonly used objects, you can insert an already made component.
