Autocad Electrical Get Drawing Wdm Properties

A special invisible block must be present on the drawing. The WD_M.dwg is found in the default symbol library. Here is an attribute list of information that is carried on the WD_M block of the drawing, sorted by category:

Drawing layout

Ladder defaults

RUNGHORV	ladder orientation: "H" = horizontal rungs (vertical ladders); "V" = vertical rungs (horizontal ladders)

RUNGDIST	default rung spacing
DLADW	default ladder width
RUNGINC	default rung-to-rung line reference increment (default = 1)
DRWRUNG	draw ladder rungs: 0 = none, 1 = draw all rungs for new ladder, 2 = skip 1, 3 = skip 2, and so on.
PH3SPACE	3-phase bus spacing value

Component tagging

TAGMODE	tag mode value: S = sequential, R = reference-based

TAGFMT	component tag format specifier (default=%F%N)

Wire number tagging

WIREMODE	wire number format: S = sequential, R = reference-based

SORTMODE	retag and wire numbering sort mode
WNUM_OFFSET	wire number placement offset distance (GBL_wd_wnum_offset); same as the project-wide +[19] value in the .wdp file. 0.0 or missing= centered on wire (default), >0.0 = offset from top or left end by given distance
WNUM_FLAGS	1's bit set = (GBL_wd_inline_gap global) auto in line wire gap adjust "ON" (see WNUM_GAP attribute for settings list) 2's +4's bits = 00 default wire number above wire 01 = below wire

Layer names

TAG_LAY	component tag layer
TAGFIXED_LAY	fixed component tag layer
DESC_LAY	description layer of the parent component
CDESC_LAY	description layer of the child component
TERM_LAY	component terminal pin numbers layer
XREF_LAY	cross-reference layer of the parent component
CXREF_LAY	cross-reference layer of the child component
LOC_LAY	component location code layer
POS_LAY	component position code layer
MISC_LAY	miscellaneous layer
COMP_LAY	layer for schematic component graphics
LINK_LAY	dashed link lines layer
LOCBOX_LAY	location box layer
WIRELAYS	valid wire layer names where "" = all valid (comma-delimited)
WIRENO_LAY	valid wire number
WIRECOPY_LAY	extra wire number layer
WIREFIXED_LAY	fixed wire layer
WIREREF_LAY	terminal and signal arrow wire number layer

Fan In/Out

FAN_INOUT_LAYS	valid layer names for Fan In/Out, single-line wires (comma-delimited)
FAN_INOUT_STYLE	Fan In/Out symbol style number

Cross-reference

XREFFMT	cross-reference format specifier (default=%N)
ALT_XREFFMT	optional cross-reference format for inter-drawing references (that is, %S-%N)
XREF_STYLE	cross-reference style: 0 = text, 1 = graphical, 2 = table
XREF_FLAGS	1's bit = include unused contacts, 2's bit (if table)= include parent coil
XREF_UNUSEDSTYLE	0 = separate reference, 1 = contact count totals
XREF_FILLWITH	cross-reference fill-with text
XREF_SORT	0 = sort by line reference, 1 = sort by pin list
XREF_TXTBTWN	cross-reference text between references (text style cross-referencing)
XREF_GRAPHIC	0 = graphic, 1 = contact mapping (text), 2 = symbol mapping
XREF_GRAPHICSTYLE	0 = JIC, 1 = IEC
