To prepare Civil 3D objects for 3D printing, you need to install Autodesk Print Studio. Installation of Autodesk Print Studio is easily accomplished by selecting Print Studio from the 3D Print panel of the Output ribbon or by selecting the Print option from the Application Menu, then selecting 3D Print. A dialog box will appear with the option to install if the program is not currently installed on your computer. The software and its drivers are easily installed by following the prompts throughout this process. Below is a link to an Autodesk Help Video that demonstrates the entire process:
After installation, the first time you select 3D Print, a dialog box (shown below) appears with the option to learn about preparing a 3D model for printing:
Selecting this option opens the following Autodesk AutoCAD Civil 3D Help window:
