Delete Unused Construction

The command “Edit|Purge” serves to delete all 2D or 3D construction elements that were used neither for creating graphic lines of the 2D drawing nor for operations.

After calling the command, the “Purge” dialog window is displayed. In it, you can set the following flags:

●Delete Unused 3D Construction. All unused 3D construction elements will be deleted. 'Unused' are considered the 3D construction elements that are not referenced by a single operation.

●Delete Unused 2D Construction. All unused 2D construction elements will be deleted, which are those not involved in creating 2D graphic lines, hatches, dimensions and other drawing elements. The named 2D constructions, that is the 2D construction elements assigned individual names are not deleted by default. To have them deleted, you would need to turn on an additional flag “Delete Unused Named 2D Elements”.

●Delete Unused Invisible Variables. All variables marked in the variables editor as "Hidden" and not used anywhere in the model will be deleted.

●Delete Unused Pages. All empty pages in the current document will be deleted.

The unused 2D pages also include the pages of workplanes created automatically by the “Draw On Face” command if the user didn't use them to create anything. Such pages are deleted together with the projections of source faces which were automatically created on those pages.

When 2D elements are deleted on a page of a 2D drawing or on the active workplane, the following additional flags are available in the command's dialog:

●Delete Unused Named 2D Elements. When this flag is set and the unused 2D constructions are deleted, the named 2D construction elements will be deleted too. In addition, this flag allows deleting the workplanes created on faces, if the projections on those workplanes include named graphic lines.

●Current Page Only. When this flag is set, the unused 2D constructions will be deleted only on the current page of the 2D drawing or on the active workplane.
