;;; FLATTEN.LSP version 2k.0, 25-May-1999
;;;
;;;-----------------------------------------------------------------------
;;;*How to Use FLATTEN
;;;
;;; This version of FLATTEN works with AutoCAD R12 through 2000.
;;;
;;; To run FLATTEN, load it using AutoCAD's APPLOAD command, or type:
;;; (load "FLATTEN")
;;; at the AutoCAD command prompt. Once you've loaded FLATTEN.LSP, type:
;;; FLATTEN
;;; to run it. FLATTEN will tell you what it's about to do and ask you
;;; to confirm that you really want to flatten objects in the current
;;; drawing. If you choose to proceed, FLATTEN prompts you to select objects
;|;; to be flattened (press ENTER to flatten all objects in the drawing).
;;; After you've selected objects and pressed ENTER, FLATTEN goes to work.
;;; It reports the number of objects it flattens and the number left
;;; unflattenened (because they were objects not recognized by FLATTEN; see
;;; the list of supported objects above).
;;;
;;; If you don't like the results, just type U to undo FLATTEN's work.
;;;
;;;-----------------------------------------------------------------------
;;;*Known limitations
;;; 1) FLATTEN doesn't support all of AutoCAD's object types. See above
;;; for a list of the object types that it does work on.
;;; 2) FLATTEN doesn't flatten objects nested inside of blocks.
;;; (You can explode blocks before flattening. Alternatively, you can
;;; WBLOCK block definitions to separate DWG files, run FLATTEN in
;;; each of them, and then use INSERT in the parent drawing to update
;;; the block definitions. Neither of these methods will flatten
;;; existing attributes, though.
;;; 3) FLATTEN flattens objects onto the Z=0 X-Y plane in AutoCAD's
;;; World Coordinate System (WCS). It doesn't currently support
;;; flattening onto other UCS planes.
;;|;
