System variable to set architectural precision?

[TroutKing]

good afternoon

 

I'm having trouble tracking down a system variable.

 

When setting variables I am not able to set my "precision". After changing my units to architectural (which works OK in the following code) I then want to set the precision to 1/128"

 

 
Sub WHATEVER()
ThisDrawing.SetVariable "LUNITS", 4
ThisDrawing.SetVariable "INSUNITS", 1
ThisDrawing.SetVariable "LWUNITS", 0
ThisDrawing.SetVariable "MEASUREINIT", 0
ThisDrawing.SetVariable "LUNITS", 0.0078125 '<------- This does not work
End Sub

 

I realize LUNITS is for decimal use, but I cannot locate it's fractional counterpart

Any ideas?

See DIMDEC variable

ThisDrawing.SetVariable "DIMDEC", 3

??? not sure about

To get the 1/128 precision for Architectural units set the LUPREC system variable to 7. The said LUNITS controls only the mode of working units.

For angles there is the AUNITS and AUPREC pair.

Ah! I think I understand now. Thank you very much for your responses! It worked.
