;;;----------------------------------------------------------------------------
;;; DESCRIPTION
;;;----------------------------------------------------------------------------
;;; C:DDCHPROP is a dialogue interface for the CHPROP command.
;;;
;;; The command looks similar to DDEMODES.  The main dialogue has an image
;;; tile, 3 buttons (layer, color, linetype), and an editbox (thickness).
;;; The 3 buttons each launch a sub-dialogue containing a list and edit box.
;;; The dialogues are all defined in the DDCHPROP.DCL file.
;;;
;;;
;;;----------------------------------------------------------------------------
;;;----------------------------------------------------------------------------
;;; Prefixes in command and keyword strings:
;;;    "."  specifies the built-in AutoCAD command in case it has been
;;;          redefined.
;;;    "_"  denotes an AutoCAD command or keyword in the native language
;;;          version, English.

;;; DESCRIPTION
;;;
;;; This function allows the user to get a listing comparable to the LIST
;;; command for most objects.  In addition, most object fields in the
;;; dialogue box are editable.  Points can be specified dynamically by
;;; temporarily dismissing the dialogue box.  Each object has a unique
;;; dialogue.
;;;
;;; Naming conventions
;;; Long function and widget names may use an underscore "_"
;;; in their names to make them easier to read, long variable
;;; names use a dash "-".
;;;----------------------------------------------------------------------------
;;;----------------------------------------------------------------------------
;;; Prefixes in command and keyword strings:
;;;    "."  specifies the built-in AutoCAD command in case it has been
;;;          redefined.
;;;    "_"  denotes an AutoCAD command or keyword in the native language
;;;          version, English.
;;;----------------------------------------------------------------------------
;;;
;;; Avoid (gc)s on load to improve load time.

;;; DESCRIPTION
;;;----------------------------------------------------------------------------
;;; C:EXCHPROP is an extended or enhanced version of ddchprop. This
;;; command gives the user the abilitie to change several characteristics
;;; of selected polyline and text objects.
;;;    The style and height of selectected text objects can be modified
;;; (including text, mtext and attribute definitions) as well as, width and
;;; elevation characteristics of selected polylines (includes lightweight and
;;; traditional polylines.)
;;;----------------------------------------------------------------------------
;;;----------------------------------------------------------------------------
;;; Prefixes in command and keyword strings:
;;;    "."  specifies the built-in AutoCAD command in case it has been

;;; DESCRIPTION
;;;                            SSX.LSP
;;;
;;; "(SSX)" -  Easy SSGET filter routine.
;;;
;;; Creates a selection set.  Either type "SSX" at the "Command:" prompt
;;; to create a "previous" selection set or type "(SSX)" in response to
;;; any "Select objects:" prompt.  You may use the functions "(A)" to add
;;; entities and "(R)" to remove entities from a selection set during
;;; object selection.  More than one filter criteria can be used at a
;;; time.
;;;
;;; SSX returns a selection set either exactly like a selected
;;; entity or, by adjusting the filter list, similar to it.
;;;
;;; The initial prompt is this:
;;;
;;;    Command: ssx
;;;    Select object/<None>: (RETURN)
;;;    >>Block name/Color/Entity/Flag/LAyer/LType/Pick/Style/Thickness/Vector:
;;;
;;; Pressing RETURN at the initial prompt gives you a null selection
;;; mechanism just as (ssx) did in Release 10, but you may select an
;;; entity if you desire.  If you do so, then the list of valid types
;;; allowed by (ssget "x") are presented on the command line.
;;;
;;;    Select object/<None>:  (a LINE selected)
;;;    Filter: ((0 . "LINE") (8 . "0") (39 . 2.0) (62 . 1) (210 0.0 0.0 1.0))
;;;    >>Block name/Color/Entity/Flag/LAyer/LType/Pick/Style/Thickness/Vector:
;;;
;;; At this point any of these filters may be removed by selecting the
;;; option keyword, then pressing RETURN.
;;;
;;;    >>Layer name to add/<RETURN to remove>: (RETURN)
;;;
;;;    Filter: ((0 . "LINE") (39 . 2.0) (62 . 1) (210 0.0 0.0 1.0))

;;; HATCHB.LSP ver 2.5
;;; Recreates hatch boundary by selecting a hatch
;;; Known problem with some elipses and splines
;;; By Jimmy Bergmark
;;; Copyright (C) 1997-2008 JTB World, All Rights Reserved
;;; Website: www.jtbworld.com
;;; E-mail: info@jtbworld.com
;;; 2000-02-12 - First release
;;; 2000-03-27 - Counterclockwise arcs and ellipses fixed
;;;             Objects created joined to lwpolyline if possible
;;;             Error-handling, undo of command
;;;             Can handle PLINETYPE = 0,1,2
;;; 2000-03-30 - Integrating hatchb and hatchb14
;;;             Selection of many hatches
;;;             Splines supported if closed.
;;; 2001-04-02 - Fixed bug with entmake of line with no Z for r14
;;; 2001-07-31 - Removed an irritating semicolon to enable polylines to be created.
;;; 2001-10-04 - Changed mail and homepage so it's easy to find when new versions comes up.
;;; 2003-02-06 - Minor fix
;;; 2003-02-17 - Area returned if no islands is found since it's not consistant
;;; 2003-05-19 - Fix to take PEDITACCEPT variable used in AutoCAD 2004 into account
;;; 2004-11-05 - Minor bugs fixed
;;; 2006-03-18 - Nothing changed from 2.1 other that it's been confirmed to work with AutoCAD 2007
;;; 2006-05-13 - Create the boundary on the same layer as the hatch using the hbl command and
;;;             on current layer/color/linetype using the hb or hatchb command
;;; 2007-02-08 - Fixed a bug with the hbl command
;;; 2008-02-29 - Support for hatches in non WCS thanks to xiaocai
;;; Tested on AutoCAD r14, 2000, 2000i, 2002, 2004, 2005, 2006, 2007, 2008, 2009
