Create Draco Files
For creating Draco™ (.drc) files, there are multiple options.
Command Line Tool
Draco's Encoding Tool is a command line tool that is able to convert a mesh or point cloud into a Draco (.drc) file. It supports the following input types:
Example for encoding a Wavefront OBJ (input.obj) into a Draco file (output.drc):
draco_encoder -i input.obj -o output.drc
See the draco_encoder documentation for usage details.
Unfortunately there's no binary distribution, so you have to build the executable yourself following Draco's build instructions.
Tip: Similar to the Encoding Tool there's a glTF Transcoding Tool that it able to apply Draco compression on glTF files. See Draco and glTF for more information.
Within Unity
In the Scene/GameObject Encoding/Decoding via Menu sample you'll find an Editor script that lets you encode meshes to Draco within the Editor.
