Quick Reference

Converts geometry into construction geometry.

Access Methods


 Ribbon: Block Editor contextual tab Constraint Parameters panel Construction Geometry


The BCONSTRUCTION command is used in the Block Editor to convert geometry into construction geometry. 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.
