I have a dimstyle that I want to set current with code. The dimstyle is called XXX, and when I set it current with the dialog, then do... Command: (getvar "dimstyle") I get this returned... "XXX" So, if I set STANDARD current, and do this... (setvar "dimstyle" "XXX") I get this returned ; error: AutoCAD variable setting rejected: "dimstyle" "XXX" I also tried... (vla-setvariable (vla-get-activedocument (vlax-get-acad-object)) "dimstyle" "XXX") I got this returned... ; error: Automation Error. Error setting system variable All of this in ADT 3.3. Anyone have any thoughts? Is there a better way to do this? My goal is to put some stuff in S::Startup so that the correct DimStyles are loaded into every drawing at startup. Best, Gordon
