Installing the New Subassembly

The Autodesk Tool Catalog files (.atc files, found in [DataLocation]\Autodesk\C3D 2011\enu\Tool Catalogs\Road Catalog) need to be modified in order to list your new subassembly in the Civil 3D Subassembly Catalog.

Note:
DataLocation in the path above depends on the operating system:
  • On Windows XP it is C:\Documents and Settings\All Users\Application Data\
  • On Windows Vista and Windows 7, it is C:\ProgramData\Autodesk\

The .atc file format for .NET subassemblies is largely the same as for VBA subassemblies except that two new tags are used:

<GeometryGenerateMode>UseDotNet</GeometryGenerateMode>

<GeometryGenerateMode> tells Civil 3D that you are using a .NET subassembly. It is placed within the <Tool> tag.

<DotNetClass Assembly="%AECCCONTENT_DIR%\C3DStockSubassemblies.dll">Subassembly.NewCurb</DotNetClass>

<DotNetClass> is used instead of <Macro> tag when using .NET subassemblies
