Geometry ID #s

[JKLINE]

I added some geometry ID numbers to a list, but I'm not seeing a way to retrieve the information of the geometry by referencing their ID #.

I thought this would get the first ID# from the list, and then get it's geometry. It gets both ends of a line, alternating between two lines. (Want to draw a line between points 1&3 and 2&4)

Example: 

            void connectLines(){
                var set = 0;
                foreach (var Line in CreaseID){
                    var geomask = new Mastercam.Database.Types.GeometryMask
                    {
                        Lines = true
                    };

                    if (set == 0){
                        var creaseGeo = SearchManager.GetGeometry(geomask);
                        foreach (var singleGeo in creaseGeo){
                            var line = (LineGeometry)singleGeo;
                            creaseX1 = line.EndPoint1.x;
                            creaseX2 = line.EndPoint2.x;
                            creaseY1 = line.EndPoint1.y;
                            creaseY2 = line.EndPoint2.y;
                            set = 1;
                        }

                    }
                    if (set == 1){
                        var creaseGeo = SearchManager.GetGeometry(geomask);
                        foreach (var singleGeo in creaseGeo){
                            var line = (LineGeometry)singleGeo;
                            creaseX3 = line.EndPoint1.x;
                            creaseX4 = line.EndPoint2.x;
                            creaseY3 = line.EndPoint1.y;
                            creaseY4 = line.EndPoint2.y;
                            set = 0;
                            CreateLine();
                        }

                    }
                }
            }

This worked like a champ. I was getting tripped up by the fact that it stores GetEntityID numbers, example 1490.

I thought it would save that Entity number, but in the list it would be [0] instead of [1490]. 

var GetEntityID()[0] = 1490 instead of pulling the item number from the list at index and then asking for that entity information.
