There are three kinds of features that define the model tree


- Feature Node (kA3DFamily_Root-kA3DFRMRoot_Node)This type of feature corresponds to a simple node in the tree, with the following structure


- Feature Package (kA3DFamily_Root-kA3DFRMRoot_Package)This node will embed multiple feature definition, to define in one time several feature with the same cad file.


- It's the case of multi-pad, with the possibility to have different depth size. \| 
- Another example, a feature that define multiple hole at different positions. \| 


- Feature Container (kA3DFamily_Root-kA3DFRMRoot_Container)This type of feature corresponds to a sub tree. Underneath, a parameter with typekA3DParameterType_Containerthat regroup all sub nodes.
