Zoom, Pan, and Rotate (ZPR)

Access: Open this function from one of the following locations:

Select the appropriate button from the Interactive UCS controls.
Select the View > ZPR section from the menu bar. Select the required function.

This group of functions is used to zoom, pan, and rotate the display.

The following ZPR (Zoom, Pan and Rotate) commands are used to manipulate the position and size of the display. Any of these commands can be terminated by pressing the middle mouse button.

For more detailed information, see ZPR Operations below.

	Center of Rotation	Select the center of rotation.
	Flip View	Rotate the view by 180 degrees along the Y axis of the display.
	Next View	Rotate to the next view orientation.
	Pan	Pan the model.
	Previous View	Rotate to the previous view orientation.
	Rotate	Rotate the model.
	Rotate by Angle	Rotate the view by a defined angle.
	Rotate Left	Rotate the model 90° to the left.
	Rotate Right	Rotate the model 90° to the right.
	Rotate to Plane	Rotate the selected plane so that it is parallel to the display.
	Zoom	Zoom in and out.
	Zoom All	Zoom in or out so that all entities are visible and occupy the entire display area.
	Zoom by Box	Zoom to the defined box selection size.
	Zoom In	Zoom in.
	Zoom Out	Zoom out.
	Zoom Selection	Zoom in or out to automatically center the display around the selected geometry.
	ZPR Lock	Zoom, Pan, and Rotate as if the CTRL key is pressed down. This enables ZPR operations using only the mouse. The display of this option is controlled in the Preferences. If the Show ZPR Lock button on interactive UCS toolbar checkbox is ON, the ZPR Lock option is available.

Notes:

Mouse shortcuts can also be used for some ZPR functions. The mouse is fully customizable. This means that these mouse shortcuts can be changed and other shortcuts (that only use the mouse buttons, for example) can be added.
Some of these operations can also be performed by the Interactive UCS and its adjacent toolbar.
To increase performance (speed) and/or the clarity of individual components during ZPR operations, use Auto Hide Entities During ZPR.
Also see the various view display options.
