How to show history of drawing entities?

The order in which the individual drawing entities were created - i.e. their history in time - can be displayed using the LISP utility History.

Xanadu History is a free LISP utility allowing to "replay" the history (order) the drawing entities were created. It is not just a slow redraw. The individual drawing objects are animated in the order of creation time, not in the assigned draw order.

Load the HISTORY.VLX in your AutoCAD session (e.g. with the _APPLOAD command). In a copy of your DWG drawing, run the HISTORY command. It will initially hide all drawing entities. Then the entities will be individually displayed in the order of creation. You can choose automatic (animated) display or single step display on pressing ENTER.

The animation speed can be controlled by the LISP variable "history_delay".
