Clipping - Limit Box

Function

This command is used to define a 3D box beyond which points are not displayed or processed.

Note: The limit box does not delete the points. It merely reduces the size and complexity of point clouds for viewing and processing.

Procedure

To define and place a limit box:

1. Click on the icon or type cwlimitbox at the CAD command line and press Enter. You are then prompted to sequentially enter three data points to define a box.

2. Using the snapping function, select a point representing one corner of the desired 3D limit box (you can also enter coordinates for this corner at the command line and press Enter).

3. Position the crosshair at the point representing the opposite corner of the desired limit box and click (or enter coordinates for the second corner at the command line and press Enter). The resulting rectangle is projected onto the work plane.

4. Position the crosshair and select a point to determine the height of the box. If you select the Height keyword, you can also enter the value of the height. Points outside the boundaries of the box are hidden from view.

   1. If all points are hidden after applying the limit box, it is likely that the limit box is defined in an incorrect position. In this case, turn the limit box OFF and try again.

   2. You can use cwclipmgr command to turn on or off any clipping records, or use cwclipoff command to turn off all clipping records of the active clipping group.
