Hi there,

I am trying to extract mate information from an open assembly. I referred to this example from SolidWorks API help: Get Mate and Mate Entities Example (VBA). For each mate under "Mates" feature in Feature Manage Design Tree, by using IMateEntity2.GetEntityParams() method, I get a set of parameters of each mate entity.

But here is a problem that I couldn't overcome. It's about how to get the name of mate entities associated in a mate by their parameters. I've done some searching on internet but with no progress. Does anyone have  idea?

//------------------------------Code--------------------------------------------------------------------//

private void ExtractMateInformation_Click(object sender, EventArgs e)
        {
            SldWorks.SldWorks swApp = new SldWorks.SldWorks();
            ModelDoc2 swModel;
            Feature swFeat;
            Face2 swFace;
            Feature swMateFeat=null;
            Feature swSubFeat;
            PathTitleName Sub = new PathTitleName();
            Mate2 swMate;
            MateEntity2 swMateEntity_1;
            MateEntity2 swMateEntity_2;
                     
            string MateFeatName = null;
            swModel = (ModelDoc2)swApp.ActiveDoc;
            swFeat = (Feature)swModel.FirstFeature();
            //  Iterate over features in FeatureManager design tree
            while (!(swFeat == null))
            {
                if ("MateGroup" == swFeat.GetTypeName())
                {
                    swMateFeat = (Feature)swFeat;
                    break;
                }
                swFeat = (Feature)swFeat.GetNextFeature();
            }
            MateFeatName = swMateFeat.Name;
            //  Get first mate, which is a subfeature
            swSubFeat = (Feature)swMateFeat.GetFirstSubFeature();
            while (!(swSubFeat == null))
            {                
                swMate = (Mate2)swSubFeat.GetSpecificFeature2();
                if (!(swMate == null))
                {
                    string MateName = swSubFeat.Name;
                    string Component1 = swMate.MateEntity(0).ReferenceComponent.Name2;
                    string Component2 = swMate.MateEntity(1).ReferenceComponent.Name2;
                    int MateType = swMate.Type;
                    int MateAlignment = swMate.Alignment;
                    bool CanBeFlipped = Flipped;
                    int Entity1Type =swMate.MateEntity(0).ReferenceType;
                    int Entity2Type =swMate.MateEntity(1).ReferenceType;
                    
                    //get two mate entities associated in this mate
                    swMateEntity_1 = (MateEntity2)swMate.MateEntity(0);
                    swMateEntity_2 = (MateEntity2)swMate.MateEntity(1);
                    
                    //get a set of entity parameters                    
                    double[] EntityParams_1 = swMateEntity_1.EntityParams;
                    double[] EntityParams_2 = swMateEntity_2.EntityParams;
                    
                }
                //  Get the next mate in MateGroup
                swSubFeat = (Feature)swSubFeat.GetNextSubFeature();
            }            
        }

Cheers,
