Topic: is it possible to set a var. without opening dwg file?

Insunits Where revit default exports it 'meters'

Without opening the file directly, no. You could look into batch scripting but it will still require an instance of AutoCAD to open, change the var, save, then close.

I'm a little foggy but can't you set variables via ObjectDBX and vla-SetVariable?

Thanks.
Nowadays i use the lee mac 'steal' routine.
This can READ various stuff without opening dwg (i think)
I was thinking about something this way

IIRC system variables are not available through ObjectDBX.

FWIW -

If presumably dealing with Document level sysvars, a small .NET LispFunction Method could be written to accept a Document's Path, sysvar name, and desired value, which would then attempt to open the Document as a side-database using ReadDwgFile(), and simply set the appropriate Database Property in lieu of calling SetSystemVariable().

Example; instead of:

Code - C#: [Select]

1. Application.SetSystemVariable("CLAYER", "LayerName")

This:

Code - C#: [Select]

1. <Database>.Clayer = LayerName.ObjectId.
