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.

Convert

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

Revert

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

Show All

Displays all construction geometry.

Hide All

Hides all construction geometry.
