Migrating AutoCAD® .NET Classic Application to ARES Commander

You can migrate .NET applications running on AutoCAD® platform to ARES Commander with minimal changes.

Replace AutoCAD® .NET assemblies with ARES .NET assemblies.
Replace Autodesk.AutoCAD namespace with Teigha namespace in the source code.

Advance Migration

If you do not want to maintain separate source code for AutoCAD® and ARES Commander, then additional steps are necessary. A single project with two build configuration solves the issue.

Step 1: Create a new build configuration for AutoCAD® and ARES Commander.

Image Removed

Step 2: Using project Properties, select all configurations one by one and define Symbol “AutoCAD” or “ARES” for the corresponding configurations.

For AutoCAD_Release configuration:

For ARES_Release:

Image Removed

Step 3: Add Conditional reference assemblies to the project using Symbols. Modify csproj file manually in the text editor to add condition for all references as in the following example.

<ItemGroup>

    <Reference Include="accoremgd" Condition="$(DefineConstants.Contains('AutoCAD'))">

      <HintPath>C:\Program Files\Autodesk\AutoCAD 2018\accoremgd.dll</HintPath>

    </Reference>

    <Reference Include="acdbmgd" Condition="$(DefineConstants.Contains('AutoCAD'))">

      <HintPath>C:\Program Files\Autodesk\AutoCAD 2018\acdbmgd.dll</HintPath>

    </Reference>

    <Reference Include="acmgd" Condition="$(DefineConstants.Contains('AutoCAD'))">

      <HintPath>C:\Program Files\Autodesk\AutoCAD 2018\acmgd.dll</HintPath>

    </Reference>

    <Reference Include="FxCoreMgd_4.03_14" Condition="$(DefineConstants.Contains('ARES'))">

      <HintPath>C:\Program Files\Graebert GmbH\ARES Commander 2018\BIN\FxCoreMgd_4.03_14.dll</HintPath>

    </Reference>

    <Reference Include="TD_Mgd_4.03_14" Condition="$(DefineConstants.Contains('ARES'))">

      <HintPath>C:\Program Files\Graebert GmbH\ARES Commander 2018\BIN\TD_Mgd_4.03_14.dll</HintPath>

    </Reference>

  </ItemGroup>

Step 4: Changes in the source code add using directives for both the application conditionally and Replace Autodesk.AutoCAD to CADApp in *.cs source files which is defined conditional declaration below.

#if  ARES

using Teigha.DatabaseServices;

using Teigha.Runtime;

using Teigha.Geometry;

using Teigha.ApplicationServices;

using Teigha.EditorInput;

using CADApp = Teigha;

#elif  AutoCAD

using Autodesk.AutoCAD.DatabaseServices;

using Autodesk.AutoCAD.Runtime;

using Autodesk.AutoCAD.Geometry;

using Autodesk.AutoCAD.ApplicationServices;

using Autodesk.AutoCAD.EditorInput;

using CADApp = Autodesk.AutoCAD;

#endif

//If we define using statement as above then while porting no need to write as below
#if ARES
Teigha.Colors.Color acadColor = Teigha.Colors.Color.FromRgb(color.R, color.G, color.B);
#else
Autodesk.AutoCAD.Colors.Color acadColor = Autodesk.AutoCAD.Colors.Color.FromRgb(color.R, color.G, color.B);
#endif

//ported code will be

CADApp.Colors.Color acadColor = CADApp.Colors.Color.FromRgb(color.R, color.G, color.B);

Step 5:

Specify separate Output folders for both configurations.

Build both configurations one by one. The builds will work with their corresponding applications.
