Właściwość DimTxtDirection

[kojacek]

LISP który działa normalnie w AC, nie działa w ZWCAD 2026.  Zauważyłem że dla wymiaru właściwość DimTxtDirection nie ma wartości. To błąd czy umyślne zaniechanie?

Zapytałem producenta o to czemu ten parametr jest pusty.
Dam znać jak dostanę odpowiedź.

Dzięki... Dla tego wymiaru (już z ciekawości przejrzałem) właściwości bez wartości jest więcej:

AltSubUnitsFactor = 
AltSubUnitsSuffix = 
DimConstrDesc = 
DimConstrValue = 
DimTxtDirection = 
SubUnitsFactor = 
SubUnitsSuffix =

Producent doradził, żeby parametr DimTxtDirection odczytać używając w skrypcie wyrażenia:

(cdr (assoc 53 (entget (car (entsel)))))

Dla pozostałych parametrów które wypisałeś analogicznie trzeba użyć innych kodów DXF:

100	Subclass marker (AcDbDimension)
280	Version number:
	0 = 2010
2	Name of the block that contains the entities that make up the dimension picture
10	Definition point (in WCS)
	DXF: X value; APP: 3D point
20, 30	DXF: Y and Z values of definition point (in WCS)
11	Middle point of dimension text (in OCS)
	DXF: X value; APP: 3D point
21, 31	DXF: Y and Z values of middle point of dimension text (in OCS)
70	Dimension type:
	Values 0-6 are integer values that represent the dimension type. Values 32, 64, and 128 are bit values, which are added to the integer values (value 32 is always set in R13 and later releases)
	0 = Rotated, horizontal, or vertical
	1 = Aligned
	2 = Angular
	3 = Diameter
	4 = Radius
	5 = Angular 3-point
	6 = Ordinate
	32 = Indicates that the block reference (group code 2) is referenced by this dimension only
	64 = Ordinate type. This is a bit value (bit 7) used only with integer value 6. If set, ordinate is X-type; if not set, ordinate is Y-type
	128 = This is a bit value (bit 😎 added to the other group 70 values if the dimension text has been positioned at a user-defined location rather than at the default location
71	Attachment point:
	1 = Top left
	2 = Top center
	3 = Top right
	4 = Middle left
	5 = Middle center
	6 = Middle right
	7 = Bottom left
	8 = Bottom center
	9 = Bottom right
72	Dimension text line-spacing style (optional):
	1 (or missing) = At least (taller characters will override)
	2 = Exact (taller characters will not override)
41	Dimension text-line spacing factor (optional):
	Percentage of default (3-on-5) line spacing to be applied. Valid values range from 0.25 to 4.00
42	Actual measurement (optional; read-only value)
1	Dimension text explicitly entered by the user. Optional; default is the measurement. If null or “<>”, the dimension measurement is drawn as the text, if ““ (one blank space), the text is suppressed. Anything else is drawn as the text
53	The optional group code 53 is the rotation angle of the dimension text away from its default orientation (the direction of the dimension line) (optional)
51	All dimension types have an optional 51 group code, which indicates the horizontal direction for the dimension entity. The dimension entity determines the orientation of dimension text and lines for horizontal, vertical, and rotated linear dimensions
	This group value is the negative of the angle between the OCS X axis and the UCS X axis. It is always in the XY plane of the OCS
210	Extrusion direction (optional; default = 0, 0, 1)
	DXF: X value; APP: 3D vector
220, 230	DXF: Y and Z values of extrusion direction (optional)
3	Dimension style name
