-This installment of the Cart3D tutorial will walk through the process of generating an unintersected component wireframe in VSP and then using Cart3D'​s intersect utility to process the geometry into a single watertight body.  If you haven'​t built the Onera M6 wing, or you don't have your own geometry to analyze, you should go back to the [[OneraM6|geometry generation]] phase of the tutorial or you can download a ready-to-go [[http://www.openvsp.org/​files/OneraM6.vsp|Onera M6 geometry]].+This installment of the Cart3D tutorial will walk through the process of generating an unintersected component wireframe in VSP and then using Cart3D'​s intersect utility to process the geometry into a single watertight body.  If you haven'​t built the Onera M6 wing, or you don't have your own geometry to analyze, you should go back to the [[OneraM6|geometry generation]] phase of the tutorial or you can download a ready-to-go [[http://hangar.openvsp.org/​vspfiles/108|Onera M6 geometry]] ​from the VSP Hangar.
  
 Although Cart3D'​s intersect tool is very robust, there are some cases it does not handle. ​ One of these cases is when surfaces of two parts are perfectly coincident. ​ This situation occurs at the wing root of the Onera M6 model created in the tutorial; the root surface of the left and right wing halves are perfectly coincident. Although Cart3D'​s intersect tool is very robust, there are some cases it does not handle. ​ One of these cases is when surfaces of two parts are perfectly coincident. ​ This situation occurs at the wing root of the Onera M6 model created in the tutorial; the root surface of the left and right wing halves are perfectly coincident.
