Components are useful for creating reusable models to be placed within other models. The most important issue to consider when creating components is how you want them to be placed when inserted into the model from the Components browser. The component axes will dictate both component orientation on insert and cutting plane (for components that are to automatically cut holes in faces, such as windows). To create a component:
- Draw your component in the orientation where it will be used. For example, if you are creating a couch component, draw it on the ground plane. If you are creating a window or door, draw it on a wall that is vertically aligned to the blue axis.
- Select the Select tool. The will change to an arrow.
- Click and hold the mouse button a short distance away from the entities you want to select to start a selection box.
- Drag the mouse to the opposite corner of the selection starting point.
- Release the mouse button when all of the elements are either partially included (left-to-right selection) or fully included (right-to-left selection) in the selection box.
- Select Edit > Make Component. Alternatively, context-click on the currently selected entities and select Make Component from the context menu. The Create Component dialog box is displayed. The following image shows the Create Component dialog box on Microsoft Windows:
- Fill out the fields in the dialog box. Ensure you make all of the appropriate selections and check all of the appropriate boxes before continuing. Specifically, decide whether the component should glue to faces in a specific orientation and cut openings.
- Click the Create button. SketchUp adds the newly created component to the In Model components.
