I've used (zz_getxd ###) earlier this year, in order to extract information from the "ADCADD_ZZ" block within AutoCAD 2009 Civil 3D Land Desktop Companion.
The problem I'm having, is that this function no longer returns the information it once did. For example, I'd use these to get the drawing scales:
Oddly, I even went back into an old drawing using 2006 LDT, and the function returns nil there too.Code:(setq vertScale (zz_getxd 341)) (setq horzScale (zz_getxd 342))
Is there another way of getting a drawing's scales?
