About the Developer's Guide Intended Audience The is designed for developers who want to customize AutoCAD® Civil 3D® or create applications using the underlying APIs. It can also be used for creating macros to automate repetitive tasks for AutoCAD Civil 3D users and for developers of custom subassemblies. AutoCAD Civil 3D APIs There are three APIs available for customizing AutoCAD Civil 3D: ■ .NET API — allows you to write extensions to AutoCAD Civil 3D in any .NET language. In general, the AutoCAD Civil 3D.NET API performs significantly faster than the COM API. Development requires...

The COM and .NET APIs are described in this guide. For more information about the Custom Draw API, see the Custom Draw API Reference (civildraw-reference.chm). In addition, an API is provided for creating custom subassemblies in .NET. See Creating Custom Subassemblies Using .NET (page 143). Which API you choose to use depends on what you want to do: If you want to: Customize the way objects are rendered in AutoCAD Civil 3D the Custom Draw API. The Custom Draw API is an extension of the AutoCAD ObjectARX API. For example, if you wanted to number the triangles on a TIN surface, you could...

Chapter 9: Creating Custom Subassemblies (page 143) Explains how to create and install custom subassemblies using Visual Basic .NET and the creation of catalog files which enables users to access custom subassemblies. You can also convert subassemblies written in VBA to .NET (see the Appendix Converting VBA Subassemblies to .NET (page 191) for more information). Appendix A: Converting VBA Subassemblies to .NET (page 191) Explains how to convert legacy custom subassemblies written in Visual Basic for Applications (VBA) to .NET. Appendix B: COM API (page 203) Covers the Legacy COM API. New...
