I am trying to select 3D point this way.

    In Pro/Toolkit you can use ProSelectionAlloc. The second parameter is Promodelitem - your 3D point.

    I want to use PROTK API for making this happen. It is based on C language structure.

      I want to use ProNoteAttachAddend() API for making leader line to my note. For this Proselection object is required. I am able to create ProSelection object but not able to set selected id and type correctly to my proselection object.

      ProSelction object can be created by using the item name and item type.

      Make ProModelItem object first (using 'ProModelitemByNameInit'), and then create ProSelection object (using 'ProSelectionAlloc').

        I am making a point programatically (so don't have name or id of this point) and select it as a proselection() object programatically.

        How do you create the point programmatically? Could you post here a piece of code? It should be a modelitem, so you should be able to use it directly in ProSelectionAlloc..

          All suggested methods are good and to the point. But in my case i got one API ProGeometryAtPointFind() works really well. This API should be used when you are certain that your 3D point will be on the part surface somewhere.

          This method will tell you surfaces or edges where the point lays on. I probably do not understand what are you exactly going to do...

          See i need model item to fill proselection object and i already know that the co-ordinates which i have they are on part. So by using this API "ProGeometryAtPointFind" i get the proselection object at that point directly. It creates proselection object on that part with appropriate data structure.

          extern ProError ProGeometryAtPointFind ( ProPart part,

                                       Pro3dPnt point,

                                       ProSelection** p_sel_arr,

                                       int* p_count);

          /*

             Purpose:     Determines the surfaces or edges on which the specified

                          point is located.  If a point lies on an edge, the function

                          does not return the neighboring surfaces.

             Input Arguments:

                part      -  The part handle.

                point     -  A three-dimensional point, in the coordinates of the part.

           

             Output Arguments:

                p_sel_arr - An array of <I>ProSelection</I>, which has information

                            about surfaces or edges on which the point is located.

                            The function allocates space for this array; free it

                    using ProSelectionarrayFree().

                p_count   - The number of items on which the point lies.

            Return Values:

                PRO_TK_NO_ERROR    - The function successfully evaluated the point.

                PRO_TK_BAD_INPUTS  - One or more of the input arguments are invalid.

                PRO_TK_E_NOT_FOUND - The surface or edge was not found.

          */
