To retain a history of the original parts of composite solids, the History
property must be set to Record (On) in the Properties Inspector when the
composite operation occurs. You can also use the SOLIDHIST system variable
to set this property.
Display and Remove the History to Modify the Composite
When you modify the composite object, you can display the history. Then
use the grips on the history subobject to modify the object. For more
information about using grips with composite solids, see
Use Grips to Manip-
ulate Composite Solids
(page 478).
You can remove the history of a selected composite object by changing its
History setting to None, or by entering the BREP command. After a history
has been removed, you can no longer select and modify the original, removed,
components of the solid. You can restart history retention for the solid by
changing its History setting back to Record.
