Thanks for helping.


Yes, We download objectarx Documentation and  Download Complete ObjectARX SDK.


We looked and studied about it. But I think our problem is that I and my friend work different area. I'm a designer. He is a programmer. 


We made some codes that use Visual Basic for application(in Autocad Tool box) and it worked.But we need to more detail about it.


For example:

SolidSelection.Select acSelectionSetAll


This code is the same use C sharp. ?



If TumPar.Count <> 0 Then
With TumPar
For xp = 1 To .Count
.Remove (1)
Next xp
End With
End If


On Error Resume Next
Set SolidSelection = ThisDrawing.SelectionSets.Add("SS01")
grpCode(0) = 0
dataVal(0) = "3DSOLID"
SolidSelection.Select acSelectionSetAll, , , grpCode, dataVal
N = SolidSelection.Count
MsgBox "countyourdrawing: " & N
