# Common Toolbar [![image-1640264225011.png](https://help.simlab-soft.com/uploads/images/gallery/2021-12/scaled-1680-/image-1640264225011.png)](https://help.simlab-soft.com/uploads/images/gallery/2021-12/image-1640264225011.png) Common Toolbar is located in the lower part of the 3D area on top of the Library, it is always accessible to the user and it includes the following: #### Select Object The Default Pick mode in SimLab Composer/Studio returns the location and the normal direction at the selection point. The geometry at the picked location will be selected in the Object Tree, and its bounding box will be displayed in the 3D area.

Different views can help the user better arrange elements in the scene.

The user can change the view mode to any of the available modes from this menu. 1\. **XRay View:** Gives x-ray effect to the models in the scene. 2\. **Edges Only View:** Displays only the edges of the models in the scene. 3\. **Solid Illustration:** Displays models in solid view, with their edges illustrated. 4\. **Solid View:** Displays models in shaded solid view.

[![image-1640265286633.png](https://help.simlab-soft.com/uploads/images/gallery/2021-12/scaled-1680-/image-1640265286633.png)](https://help.simlab-soft.com/uploads/images/gallery/2021-12/image-1640265286633.png) **Default view behavior** The mouse behavior will be as shown in the table below:
**Navigation****Mouse Button**
PanMiddle mouse button
RotateLeft mouse button
ZoomRight mouse button
**Camera Pan** Changes the behavior of the left mouse button, to Pan. **Camera Zoom** Changes the behavior of the left mouse button, to Zoom. **Rubber band** This function changes the selection mode in the 3D area and it has three options: **Rubber Band Selection:** Changes the selection icon to a square band, allowing the user to window select more than one geometry in the 3D area. **Append To Current Selection:** The selection icon will show a ‘+’ sign inside the square band. The user can window select more geometry in a different section of the 3D scene, without losing the previous selections. **Remove from Current Selection:** With a ‘-‘ sign added to the band, the user can remove geometry form selection, without losing previous selections. --- #### Fit all Updates camera to fit all geometry in the scene within the active view area. #### Zoom to Object Updates the camera in the active viewport, to zoom to the selected object. In case the user presses the button without selecting an object, a message will be displayed on top of the Common Toolbar asking him to do so. #### Switch Between Parallel and Perspective Views Switches the camera between perspective and parallel modes, in the active viewport. For engineers who are used to parallel mode, this option would be helpful. #### Capture View image Captures an image for the current view from the scene, and opens a dialog to save it.
