== What is it? ==

'''.cc3d''' files are the simulation project files for use with !CompuCell3D.  They essentially are an XML file that is stored in a directory with the other simulation files.  '''.cc3d''' files were introduced in to !CompuCell3D version 3.6.0.

===An Example:===
Below is a simple example of a '''.cc3d''' file. It essentially defines all the files need for the simulation.  In this case the simulation files reside in the directory '''Simulation''' which resides in the same directory as the '''.cc3d''' file.
{{{
<Simulation version="3.6.0">
    <XMLScript>Simulation/Cellsort.xml</XMLScript>
    <PythonScript>Simulation/Cellsort.py</PythonScript>
    <Resource Type="Python">Simulation/CellsortSteppables.py</Resource>
   <PIFFile>Simulation/Cellsort.piff</PIFFile>
    <Resource Type="Field" Copy="No">Simulation/FGF.txt</Resource>
</Simulation>
}}}
