You can run scripts in EPLAN without having licensed the EPLAN API. Scripts are executable program code, written in C# (*.cs files) or Visual Basic.NET (*.vb files). Scripts always exist as source code. When you start a script, it will be loaded into the system, compiled and then executed. 

For scripting, go to the ribbon item File > Extras > Interfaces. You will find the category Scripts.

 

 

 

After calling File > Extras > Interfaces > Scripts > Run, a file dialog appears and a script file to execute can be selected. 

 

In script following assemblies can be used:   

• System
  • Namespace System
• System.Drawing
• System.Windows.Forms
  • Namespace System.Windows.Forms
• System.Net.Http
  • Namespace System.Net.Http
• System.IO.Compression.FileSystem
• System.Xml.LINQ
• System.Xml
• System.Core
  • Namespace System.Linq
• Newtonsoft.Json

 

Also these EPLAN assemblies are referenced by default: 

 

• Eplan.EplApi.Baseu
  • Namespace Eplan.EplApi.Base
• Eplan.EplApi.ApplicationFrameworku
  • Namespace Eplan.EplApi.ApplicationFramework
  • Namespace Eplan.EplApi.Scripting
• Eplan.EplApi.Guiu
  • Namespace Eplan.EplApi.Gui
  • NameSpace Eplan.EplApi.Scripting
• Eplan.EplApi.MasterDatau
  • Namespace Eplan.EplApi.MasterData
• Eplan.IdentityClient.Authentification
  • Namespace Eplan.IdentityClient.Authentification
• Eplan.IdentityClient.Types
  • Namespace Eplan.IdentityClient

 

There is no way to reference additional assemblies (.NET framework, EPLAN or other providers)! 

This feature is only available for EPLAN API developers having "EPLAN API Extension" license.
