Troubleshooting guide #

Why I can’t run my plugin in Civil 3D or in console mode? #

You need to ensure that the directory of your plugin and test on the plugin is in the Trusted Location of AutoCAD system.

Ribbon UI items are missing! #

Reset the Civil 3D/AutoCAD to default; refer to here. Keep in mind that it could take a long while ( for the backup process), though.

My Civil 3D files are read only! #

It could be that they are located on a network drive or on Program File drive that you don’t have write access to. So do try to SaveAs it to another location ( such as your AppData folder) and see whether the files can be written or not.

Why there is no file/folder dialog box? #

it’s because the FILEDIA command is being set to 0. Set it to 1 from command line.


Civil 3D files, samples and resources #

Civil 3D ships with default files, samples and “resources”. Here are the locations that you can lookup if you want to find them. You can also refer to here.

  1. %ProgramFiles%\Autodesk\AutoCAD 20XX\C3D\Sample, This is where you can find API samples
  2. %ProgramFiles%\Autodesk\AutoCAD 20XX\C3D\Help. This the locations of the help files. In this folder, you can also find a lot of drawings used in the tutorial ( such as this one)
  3. %ProgramData%\Autodesk\C3D 20XX\enu, This is the location for Pipes Catalog, Pressure Pipes Catalog, Assembly and all. In other words, the resources
  4. %LocalAppdata%\Autodesk\C3D 20XX\enu\Template. This is where the template files for Civil 3D (such as where the default styling for Civil 3D is located, in *.dwt extension) is located.

Usage #

  1. Turn on coordinates in order to get a feel of where you are as you mouse hover across a drawing.
  2. To locate an exact point, at the command line, type in ZOOM C X,Y R, where X and Y are your coordinates, and R is the Height of the View, which corresponds to your zoom level.
  3. Press F3 to turn on/off for the Snapping.
