Reading a System Variable from an external drawing

[nick.seman]

Hello:

I have written some code that allows the user to select a project directory through which it finds all the DWG's in the directory structure and creates a report listing each drawing's name and the names of each drawing's xreferenced files along with their insert units.  I would also like to include the insunits value for each parent drawing however I am having difficulty getting that to work.

I cannot use the ThisDrawing.GetVariable("InsUnits") as I never have the parent drawing open or active.  I use  AXDBLib.AxDbDocument to set a variable as the document, then look for the blocks (isxref) inside of it.  That works but apparently the object does not support the GetVariable method.

I have also tried setting an object equal to the drawing's database however I am not finding that I can extract system variable information that way either.

I apologize as I am sure I am butchering the terminology here - I am not a programmer . . .

I appreciate any direction you may be able to provide.  In short - I would like to extract the value of a system variable from a drawing other than the currently open drawing.

Thanks;

Nick

OK - alternatively - is it impossible to extract a system variable value from a drawing that is not currently open ?

Thanks;

I haven't tried getting a var from an axDbDocument, but I don't see why you can't. Instead of using ThisDrawing, use the axDbDocument object.

Just did a test to confirm and you can't get a variable using AxDb.

Hi Ed:

Thanks for checking this out and I apologize for not getting back to you after your first post.

I did try what you suggested and came to the same result that you did.

Thanks again,

Nick
