For each model space viewport, you can create a bounding prism – an area in a three-dimensional space, beyond which all the graphics are not displayed.

 

The area is defined as a rectangular or polygonal prism with grips. The prism can be:

·         created by specifying a contour on the screen,

·         created on the basis of an existing polyline,

·         based on a bounding box of selected objects.

The prism above the XY plane of the UCS is blue, below it is orange. The grey outline of the prism is displayed in the XY plane.

 

Drag grips to place the upper and the lower prism cutoff planes. Otherwise the upper and lower displaying area will be unlimited.

 

A prism is created taking into account the direction of the UCS axes. The following is an example of constructing a prism based on the same polyline, but in different UCSs.

 

 

 

For each model space viewport, its own bounding prism should be created.

 

An existing prism can be changed, deleted or disabled/enabled. If the prism is disabled, graphics outside the prism become visible. Disabled prism object is still present in the model space and can be switched on later.

When saving a document, the prism is also saved.

 

Options:

New

Create a new bounding prism for the current view of the model space.

Delete

Delete the existing bounding prism in the current view of the model space.

Modify

Change the existing bounding prism in the current view of the model space. Grips appear on the prism that allow you to change its geometry.

Enable

Activate the effect of an existing prism on the current view of the model space. Enabled by default.

Disable

Inactivate the effect of an existing prism on the current view of the model space. Prism is preserved, but does not limit the space of the view.

Exit

Exit command.

 

Command prompts when choose the New option:

polyLine

Select an existing closed polyline that will define the contour of the prism. Then, using grips, set the upper and lower prism cutoff boundary, if necessary. The prism will be built in the direction of the UCS axes of the current view.

Selection

Select the objects around which a rectangular prism will be built. Then, using grips, change the upper and lower prism cutoff boundary, if necessary.

Rectangular

Draw a rectangular contour that will define the contour of the prism. Then, using grips, set the upper and lower prism cutoff boundary, if necessary.

Polygonal

Draw a polygonal contour that will define the contour of the prism. Then, using grips, set the upper and lower prism cutoff boundary, if necessary.

eXit

Finish the process of creating a new prism.
