1. Displaying Objects

2. Objectives After completing this lesson, you will be able to: Identify tools that control the drawing view display. Use the Pan Realtime command to perform real time pan operations in the drawing. Use the Zoom Realtime command to perform real time zoom operations in the drawing. Use different Zoom commands to control the view magnification. Use a wheel mouse to zoom and pan in the drawing. Use the Regen command to regenerate the drawing.

3. Display Tools Most of the time you will use the wheel on your mouse to zoom in and out of display views in your drawing. Additional zoom tools are located on the Navigate panel in the View tab on the toolbar ribbon.

4. Display Tools You can reposition the center of your view on the drawing by using the Pan command. Just like panning with a video camera, panning your drawing changes only the position of your view of the drawing, not the location or magnification of objects in the drawing.

5. Display Tools You can reposition the center of your view on the drawing by using the Pan command. Just like panning with a video camera, panning your drawing changes only the position of your view of the drawing, not the location or magnification of objects in the drawing.

6. Command Options While in the Pan command you may access other Pan and Zoom options when you right-click in the drawing window to display a shortcut menu.

7. Wheel Mouse Features The wheel mouse is a variant of the standard pointing device that is modified with a small wheel between the left and right buttons. You can rotate this wheel in small increments. You can use the wheel to zoom and pan in your drawing without using any commands. When zooming in, the location near your cursor is the focal point of the zoom and thus remains on the screen. The ZOOMFACTOR system variable controls the incremental change, whether forward or backward. The higher the number of the variable, the greater the zoom.

8. Wheel Button Modes You can set the wheel button to function in two different modes. The value of the MBUTTONPAN system variable controls whether panning is supported. If MBUTTONPAN is set to 1, the PAN command is activated when you use the wheel. If MBUTTONPAN is set to 0, the Object Snap menu is displayed when you use the wheel

9. Regen Use the Regen command to regenerate all the geometry in the drawing. Use the Regenall command to regenerate all the geometry when there are multiple drawing viewports. When you regenerate the drawing, the screen coordinates for all objects in the drawing are recomputed and the drawing database is reindexed for optimal display performance.

10. Guidelines When Regenerating Large Drawings Because regeneration recalculates the screen coordinates for all objects in the drawing, it usually takes longer to regenerate large drawings than smaller ones. If you experience performance decreases on larger drawings, consider setting REGENMODE = 0 to prevent automatic regeneration. You can manually regenerate the drawing when you need to.

11. Activity #1 Exercise: Zoom and Pan in the Drawing-

12. To complete this activity, follow the steps below: Note: For the step 1, in case you can’t find the file, you can open any Sample Drawing shown in your autocad .

13. Activity #2 Exercise: Hands-On Tour

14. To complete this activity, follow the steps below: Note: For the step 1, in case you can’t find the file, you can open any Sample Drawing shown in your autocad .

15. Summary Now that you have been introduced to several core features, you can begin learning how to create geometry. Having completed this lessons , you can: 1. Identify and state the purpose of the main interface elements. 2. Open, create, and save drawings. 2. Use the Zoom and Pan commands to view different areas of the drawing.
