About Tracking Drawing Changes

The Mark/Verify tool can help you track changes made to a project drawing set during any phase in the engineering process. Before you send your drawings out for review, use the Mark option. Each AutoCAD Electrical toolset component, wire number, and beginning ladder reference is invisibly marked and referenced in a table in the scratch database file of the current project. When the drawings are returned, you can use the Verify option to generate a report of changes. The report includes a list of all added, changed, copied, and deleted components and wire numbers. Changes made using AutoCAD, AutoCAD LT, or AutoCAD Electrical toolset are all detected.

For AutoCAD Electrical toolset to detect if a component or wire number is deleted, it must reference the MARKVERIFY table that is saved in the database file of the project. If the project database file is erased after the Mark option is run, then a subsequent Verify command cannot report deleted items since it is limited to reporting only changes involving new inserts, copies, and edited components and wire numbers.

The Verify command detects and reports changes to the following:
