Set Fractional Dimension Style Linear Resolution in Rhino Common API

Grasshopper

Hi All,

I am trying to create a grasshopper node in C# that will create a dimension style in rhino. I found a good portion of code that started me off from this forum post:

I have been able to change the dimension style so that it shows up in fractional dimensions, but I cannot seem to find out how to set the linear resolution of the fractional dim style. Currently the dimension style automatically outputs to the nearest 1/4" but I am looking to create a dimension style that can output to the nearest 1/16". I combed the rhino common api documentation and cannot seem to find which property in the DimensionStyle class controls this.

The current snippet of code that I have is this

  private void RunScript(string Name, double Height, ref object A)
  {
    var style_name = Name;
    var text_height = Height;

    //Find if the dimension style exists
    Rhino.DocObjects.DimensionStyle ds = Rhino.RhinoDoc.ActiveDoc.DimStyles.FindName(style_name);

    if (ds == null)
    {
      Rhino.DocObjects.DimensionStyle dimStyle = new Rhino.DocObjects.DimensionStyle(){
          Name = style_name,
          Id = Guid.NewGuid(),
          DimensionScale = 1,
          DimTextLocation = Rhino.DocObjects.DimensionStyle.TextLocation.InDimLine,
          DimensionLengthDisplay = Rhino.DocObjects.DimensionStyle.LengthDisplay.InchesFractional,
          LengthResolution = 2,
          ArrowLength = 1,
          ArrowType1 = Rhino.DocObjects.DimensionStyle.ArrowType.None,
          ArrowType2 = Rhino.DocObjects.DimensionStyle.ArrowType.None,
          TextGap = 1,
          TextHeight = text_height,
          FixedExtensionOn = false,
          ExtensionLineExtension = 0.5,
          ExtensionLineOffset = 2,
          ToleranceResolution = 16,
          Suffix = "\""
          };

      // Add the newly created text style to the document
      Rhino.RhinoDoc.ActiveDoc.DimStyles.Add(dimStyle, false);

      //find it again
      ds = Rhino.RhinoDoc.ActiveDoc.DimStyles.FindName(style_name);
    }

    // Set the newly created text style as the current style
    Rhino.RhinoDoc.ActiveDoc.DimStyles.SetCurrent(ds.Index, false);
    Rhino.RhinoDoc.ActiveDoc.Views.Redraw();

    A = ds;


  }

Here is where the linear resolution for fractional units is located in the properties for a dimension in rhino:
