is there a way to read some systemvariables with ObjectDBX?

I vaguely remember it returns the system variables from current drawing in which your code is excuted (could be wrong).
Suggestion: Store the system variables that you're interested in in a custom dictionary or attach as xdata to some objects in the drawing and later you can access them via objectdbx.

Since ObjectDBX is most useful with unopened drawings, and AutoCADs' System Variables are either stored in the drawing or at the application level, why (if I may be so bold to ask) would you want to read them?

Just wondering what you're trying to do.

I need to check is the drawing is metric or imperial.
AutoCAD System Variables Measurement

0 is Imperial
1 is Metric
be for open or insert the files as block

Not sure exactly but I think this will be impossible
do doing with ObjectDBX method IMHO
Try this instead:

Code: [Select]
Option Explicit

Public Function GetVars(selfiles As Variant, sysVarName As String) As Variant


Dim fName As String
Dim acdoc As AcadDocument
Dim sysvar() As Variant
Dim m As Integer

For m = 0 To UBound(selfiles)
fName = selfiles(m)

Set acdoc = Application.Documents.Open(fName, True)
ReDim Preserve sysvar(m)
sysvar(m) = acdoc.GetVariable(sysVarName)
acdoc.Close
Next m

GetVars = sysvar

End Function
Public Sub FindFile(ByRef files As Collection, strDir, strExt)

  Dim strFileName
  If (Right(strDir, 1) <> "\") Then
    strDir = strDir & "\"
  End If
  strFileName = Dir(strDir & "*.*", vbDirectory)
  Do While (strFileName <> "")
    If (UCase(Right(strFileName, 3)) = UCase(strExt)) Then
      files.Add strDir & strFileName
    End If
  strFileName = Dir
  Loop
 
End Sub
Sub Test()
Dim dmod
dmod = ThisDrawing.GetVariable("SDI")
If dmod <> 0 Then
ThisDrawing.SetVariable "SDI", 0
End If
Dim path As String
path = "D:\AUTOLISP\LISPS\PRIMITIVES\#FILE&S\PURGE" '' change your path here
Dim collFiles As New Collection
Call FindFile(collFiles, path, "DWG")
Dim i As Integer
ReDim selfiles(collFiles.Count - 1) As String
For i = 1 To collFiles.Count
selfiles(i - 1) = collFiles.Item(i)
Next
Dim sysvar() As Variant
sysvar = GetVars(selfiles, "measurement")

ThisDrawing.SetVariable "SDI", dmod

Dim dataVar(999, 1) As Variant
For i = 0 To UBound(sysvar)
dataVar(i, 0) = selfiles(i)
dataVar(i, 1) = sysvar(i)
Next

End Sub

What version of AutoCAD are you using?

In that case, I think there is a way you can do it through the .NET API using C# or VB.NET.

Are you interested in giving it a try?

Give me a little time to formulate something, and I'll post back with some starter code.

This C# code should get you started.  I translated this from some similar C++ code of mine, but hopefully the .NET gurus will come along and point out anything stupid I may have done.

Code: [Select]
using System;
using System.IO;
using System.Text;

using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.DatabaseServices;

namespace MetricOrImperial
{
    public class Main
    {
        public static int metricOrImperial(string fileName)
        {
            if(!File.Exists(fileName)) return -1;
            Database db = new Database(false, true);
            try
            {
                db.ReadDwgFile(fileName, System.IO.FileShare.Read, false, string.Empty);
                return db.Measurement == MeasurementValue.English ? 1 : 0;
            }
            catch (Exception e)
            {
                Application.DocumentManager.MdiActiveDocument.Editor.WriteMessage(e.ToString());
                return -1;
            }
        }
    }
}

You're welcome.

By the way, I think I got the return values backwards (assuming you want to follow the convention of the MEASUREMENT system variable).  It should return 0 for English and 1 for Imperial.

The AutoCAD System Variables Measurement  is the autocad way i think
for  Autocad Mechanical i wrote  this function

and  will try to convert this function in a C# code

Public Function Mcad_StandardIsMetric() As Boolean
Set symbb = ThisDrawing.Application.GetInterfaceObject("SymBBAuto.McadSymbolBBMgr")
Set Ge = ThisDrawing.Application.GetInterfaceObject("Ge.Application")
Set stdmgr = symbb.StandardMgr
'------------------------------------------------------------
Set currStand = stdmgr.CurrentStandard
 Mcad_StandardIsMetric = currStand.IsMetric
End Function
