How to correctly SplitFaces (all of them)?

[Anonymous]

Hi, i need to Split Faces (All).

I want to select "Faces" => Red lined object

Selecting "Faces"

Then i need to select "Split Tool" => Red themed object

Selecting "Split Tool"

Description of "SplitFaces" method is this:

SplitFeature SplitFaces(object SplitTool, bool SplitAll = true, object FacesOrBody = null)

And by definition, SplitTool can be WorkPlane, WorkSurface, SurfaceBody or a Path.

I know (thanks to the Split window in Inventor):

SplitTool => Red themed object

SplitAll => will be True

FacesOrBody => is optional, so i don't really know if i really need this

// Red themed object
PartComponentDefinition partComDef = (PartComponentDefinition)occ.Definition;
// Red lined object
PartComponentDefinition targetDef = (PartComponentDefinition)_selected.Definition;

// what i have tried
SplitFeatures splitFea = targetDef.Features.SplitFeatures;
splitFea.SplitFaces(occ.SurfaceBodies[0], true, targetDef.SurfaceBodies[1]);
splitFea.SplitFaces(occ.SurfaceBodies[1], true, targetDef.SurfaceBodies[1]);
splitFea.SplitFaces(occ.Definition.SurfaceBodies[0], true, targetDef.SurfaceBodies[1]);
splitFea.SplitFaces(occ.Definition.SurfaceBodies[1], true, targetDef.SurfaceBodies[1]);
splitFea.SplitFaces(partComDef, true, targetDef.SurfaceBodies[1]);
splitFea.SplitFaces(partComDef.SurfaceBodies[0], true, targetDef.SurfaceBodies[1]);
splitFea.SplitFaces(partComDef.SurfaceBodies[1], true, targetDef.SurfaceBodies[1]);
splitFea.SplitFaces(partComDef.Features.ReferenceFeatures[0].SurfaceBody, true, targetDef.SurfaceBodies[1]);
splitFea.SplitFaces(partComDef.Features.ReferenceFeatures[1].SurfaceBody, true, targetDef.SurfaceBodies[1]);
splitFea.SplitFaces(partComDef.Features.ReferenceFeatures[0].SurfaceBodies[0], true, targetDef.SurfaceBodies[1]);
splitFea.SplitFaces(partComDef.Features.ReferenceFeatures[0].SurfaceBodies[1], true, targetDef.SurfaceBodies[1]);
splitFea.SplitFaces(partComDef.Features.ReferenceFeatures[1].SurfaceBodies[0], true, targetDef.SurfaceBodies[1]);
splitFea.SplitFaces(partComDef.Features.ReferenceFeatures[1].SurfaceBodies[1], true, targetDef.SurfaceBodies[1]);

What i am doing wrong?
