How to Revit 2016 api Create Dimension between Grid

[cao2013]

on Revit 2014,my program ok,but on Revit 2016，it's give me a error,I search web along time,have not find the Reason

Main code
====================================
ReferenceArray refArray = new ReferenceArray();//分尺寸
foreach (ElementId e in eSet)
{
if (doc.GetElement(e).GetType() == typeof(Grid))
{
Grid gr = doc.GetElement(e) as Grid;
Curve cv = gr.Curve;
refArray.Append(cv.Reference);
}
}

if (!doc.IsFamilyDocument)
{
doc.Create.NewDimension(doc.ActiveView, line, refArray);//分尺寸
}
else
{
doc.FamilyCreate.NewDimension(doc.ActiveView, line, refArray);//分尺寸
}
====================================

Hello,

how you create the "line" ?

[cao2013]

The "line"'s start point is pick a point(snap on a Grid point),end point Calculation by start point,Increasing along the X axis.

 thinks.

Dear cao2013,

Have you debugged your code?

If not, please do.

The answer is probably quite simple.

Nobody but you can debug your code without a full and really minimal reproducible case to examine:

In 2016, get the grid reference for dimensioning like this

Reference gridRef = null;
Options opt = new Options();
opt.ComputeReferences = true;
opt.IncludeNonVisibleObjects = true;
opt.View = doc.ActiveView;
foreach (GeometryObject obj in grid.get_Geometry(opt))
{
if (obj is Line)
{
Line line = obj as Line;
gridRef = line.Reference;
}
}
