2020: ObjectDBX test

Anonymous — Thu, 30 Jan 2020 18:10:02 GMT

Hello Everyone,

Two days I'm diving into ObjectARX/ObjectDBX areas to create little prove of concept for my project.

My goal is to iterate 9000 dwg files and to extract some data from them.

My environment:

1. Windows 10 Pro 64bit

2. AutoCAD 2019 - commercial license

3. Installed ObjectARX 2020 Wizards (Autodesk_ObjectARX_2019_Win_64_and_32_Bit)

4. Visual Studio 2017 Community edition

5. AutoCAD 2020 .NET Wizards (not necessary but installed)

I created Visual Basic Console App (.NET Framework) project (just try ot open DWG file) with dll refs only for ObjectDBX from ObjectARX(acdb23.lib,acge23.lib,acgiapi.lib,axdb.lib,rxapi.lib,acismobj23.lib) with just one executable source as following :

Imports Autodesk.AutoCAD.DatabaseServices
Module Module1

    Sub Main()
        Try
            Dim db As Database
            db = New Database(False, True)
            db.ReadDwgFile("C:\WORK\Tests\20200129\dobrich.dwg", System.IO.FileShare.ReadWrite, False, "")
            db.CloseInput(True)
            HostApplicationServices.WorkingDatabase = db
            Using tr As Transaction = db.TransactionManager.StartTransaction()

            End Using

            Debug.Write("End")
        Catch ex As Exception
            Debug.WriteLine(ex.Message)
        End Try
        Debug.WriteLine("End")
    End Sub

End Module

But I have always such error:

Exception thrown: 'System.InvalidProgramException' in ConsoleApp5.exe
Common Language Runtime detected an invalid program.

I know that such error is common if I use ObjectARX dll ourside of ObjectDBX because I will need AutoCAD app, but this is not the case in my code.

I cannot understand why I have such error in case of exploanation in Autodesk documentations that must be working fine.

Any suggestion for fix of that error ?

Regards

Perhaps I've misunderstood what you are trying to do, but the ObjectARX SDK can only be used to create C++ or .NET dlls that can be loaded into AutoCAD and run from within AutoCAD. It can't be used to create a standalone exe that does not need AutoCAD.

If you want to create a standalone console application that does not require AutoCAD, then you will need to use the RealDWG SDK which is a licensed SDK that is not free.

According official sources you are not right because ObjectARX is a plugin SDK, but contains ObjectDBX (for standalone apps just few dll (see below), RealDWG is the license version ofObjectDBX )

Official info from techsoft3d (Autodesk)

To test and trial RealDWG, please follow these steps:

Download and read about system requirements for the ObjectARX SDK here. These libraries are actually the API for AutoCAD (So you can see how well integrated RealDWG is!)
If you don’t have AutoCAD, you can download a 30-day trial version here.
If you’re not familiar with ObjectARX programming, you can get started here. Also have a look at the sample projects that come with the SDK.
RealDWG uses the ObjectDBX part of the Object ARX libraries. (Please be aware that any UI or draw functions are NOT included in RealDWG. However, all file reading, file writing and geometry functions are.)

Using the ObjectARX SDK, it is possible to do a “proof-of-concept” to validate the intended behavior. As RealDWG is a subset of ObjectARX you need to make sure critical features are kept within the RealDWG parts of the API.

See below for specific instructions about how to test if you are using Managed (.NET) code or Native (C++) code.

Managed code (.NET)

You’ll be using the managed API of ObjectARX. The ObjectARX features that are specific to RealDWG only, can be found in the namespaces of the AcDbMgd.dll:

However, you need to make sure no critical calls are made to the AcCoreMgd.dll, which contains overlapping namespaces ‘GraphicsSystem’ and ‘Runtime’ (this dll is not part of RealDWG):

Additional dll’s in ObjectARX that are also available in RealDWG:

acdbmgdbrep.dll
AcAxDb23res.dll

Native code (C++)

The ObjectARX functionality that is also available in RealDWG is restricted to these libraries:

ac1st23.lib
acdb23.lib
acdbmgd.lib
AcDbPointCloudObj.lib
acge23.lib
AcGeolocationObj.lib
acgiapi.lib
acismobj23.lib
acModelDocObj.lib
AcMPolygonObj.lib
AcPal.lib
AcSceneOE.lib
axdb.lib
rxapi.lib

from the utils folders

AecModeler.lib
AdImaging.lib
AdIntImgServices.lib
acbr23.lib
acgex23.lib
AsdkHlrApi23.lib

@artc2 better than anyone on this forum know how to use ObjectARX and ObjectDBX (RealDWG)

Without RealDWG you can not create exe-file for reading/writing dwg-file.

Interesting how to buy RealDWG without way for understand what is possible to do by testing of ObjectDBX in standalone mode.

Thank you for both answers!

Ask this question in techsoft3d.

Can you confirm that testing of ObjectDBX (dwg open/read) is possible only by plugin for AutoCAD?

You will need an appropriate host application to load and test a DBX module. This could also be RealDWG based app like Autodesk Trueview that allows to load DBX modules.

Anyway I would recomment AutoCAD because it might be tricky to test your functions if you are not using AutoCAD.

The usual way is to to write a command in an ARX module that calls your functions. If you use another host app you have to figure out a way to make it call your function.

Sorry but this code has nothing similar with RealDWG and ObjectDBX

Original problem can be easy solved with ObjectARX or AutoCAD .NET API, AcCoreConsole and bat-file.

No you should not remove posts. By the way, you can not remove your post - it is possible only with help of forum moderators.
