    How to get sketch line information using dimension

    Saugat Kc

      I want to get sketch line information using dimension property. I was successful getting all sketch dimension values as well as sketch line information(start point, end point) separately using their own properties but I want to get a link between these two information for example if I have a dimension information, i should be able to get sketch information on which this dimension has been created. More details is shown in figure:


      Is there any way doing this. I was not able to get any concrete information from API as well.

          I can't find the way to get line length directly too.

          But I think if you can get start point and end point, you can calculate length like below.

          sqrt(( end point x - start point x)^2+(end point y - start point y)^2)

            Try DisplayDimension::GetAnnotation and then Annotation::GetAttachedEntities3.

                    Hello Artem,

                    There is a slight mistake on implementing correct dimension annotation. When I select the line segment after getting its entities, it is selecting following line segment rather than itself. for example.


                    When dimension L is selected, it is giving me red circled line as its line segment. Similarly when F is selected, it is giving blue circled as its line segment.

                    My implemented code is as follows:

                    public List<DimensionList> getSunpouData(Feature swFeature)


                                double value = 0.0;

                                DisplayDimension swDisplayDim = swFeature.GetFirstDisplayDimension();

                                List<DimensionList> ListDimension = new List<DimensionList>();



                                while (swDisplayDim != null)


                                    SolidWorks.Interop.sldworks.SketchSegment StartEndSegment = default(SolidWorks.Interop.sldworks.SketchSegment);



                                    Annotation swAnnotation = swDisplayDim.GetAnnotation();

                                    Dimension swDim = swDisplayDim.GetDimension();  //IT GETS CORRECT DIMENSION


                                    object[] annoEntities = swAnnotation.GetAttachedEntities3();

                                    var EntityType = swAnnotation.GetAttachedEntityTypes();

                                    int i = 0;



                                    foreach (object EntityObj in annoEntities)


                                        if (EntityType[i] == 10) // ONLY FOR LINE SEGMENT AS ALL ANNOTATION DOES NOT PROVIDE POINT INFORMATION


                                            StartEndSegment = (SolidWorks.Interop.sldworks.SketchSegment)EntityObj;

                                            StartEndSegment.Select(false);     //SELECT CIRCLED LINE SEGMENT.

                                            SolidWorks.Interop.sldworks.Sketch swSketch = StartEndSegment.GetSketch();

                                            SolidWorks.Interop.sldworks.SketchLine swSketchLine = (SolidWorks.Interop.sldworks.SketchLine)StartEndSegment;

                                            SolidWorks.Interop.sldworks.SketchPoint swSkStartPoint = swSketchLine.GetStartPoint2();   //CIRCLED LINE VERTICES ARE GIVEN

                                            SolidWorks.Interop.sldworks.SketchPoint swSkEndPoint = swSketchLine.GetEndPoint2();      //CIRCLED LINE VERTICES ARE GIVEN






                                    value = swDim.GetSystemValue2("") * 1000;

                                    string swDimensionName = swDim.Name;

                                    ListDimension.Add(new DimensionList() { DimensionName = swDimensionName, DimensionValue = value});



                                    swDisplayDim = swFeature.GetNextDisplayDimension(swDisplayDim);


                                return ListDimension;



                    What can be my possible mistake ?
