Subject: Using .NET applications

CADdirect supports the .NET programming language in two ways:

•   .NET Classic — More closely matches the .NET interface used by AutoCAD.

•   .NET based on COM — Initial .NET interface supported by CADdirect.

To prepare a .NET custom application

   1   In the .NET application, inherit the IICadPlugin interface that is defined in Intelli­CAD as:

public interface IIcadPlugin

{

   void PluginLoaded(object sender, EventArgs e);

   void PluginUnLoading(object sender, EventArgs e);

}

Where PluginLoaded() is called on plug-in load, the sender argument is a COM Interop model class CADdirect.Application for working with (storing it as a class member), and PluginUnLoading()is called right before the plug-in is unloaded.

To load a .NET Classic custom application

   1   Do one of the following:

•   On the menu, choose Tools > Load Classic .NET Application.

•   Type netload and then press Enter.

   2   In the Open an Assembly dialog box, select the .NET .dll file that you want to load, and then click Open.  

.NET Classic custom applications can also be run automatically when the program starts.
You can add .dll files for .NET to a startup suite or use a script. For details, see CADdirect_starts.htm#XREF_77322_Running">Load­ing custom applications automatically when CADdirect starts.
