Converts block geometry into construction geometry, which may be hidden or displayed.


The BCONSTRUCTION command is used in the Block Editor to convert geometry into construction geometry. You can use this geometry as a reference for other geometry in the block. This command also controls the display of construction geometry and changes construction geometry back to regular geometry.

Construction geometry is not displayed in the block reference; in the Block Editor it is displayed with a gray dashed linetype. You cannot modify the color, linetype, or layer of the construction geometry.

The following prompts are displayed.


Converts the valid selected objects into construction geometry and displays the number of objects converted. Authoring objects are not converted.


Changes the selected objects back to regular geometry. The geometry is set to the current layer.
