NewDimension - dimension created but not visible

[boostyourbim]

Hi,

I'm trying to create a dimension referencing lines in a family. The code below creates the dimension but it is not visible in the view. The newly created but invisible dimension is listed in RevitLookup. Any ideas why isn't shown in the project?

RVT attached with code as a document macro.

Thanks

Harry

Here is the RVT

A couple of suggestions:
Check that the dimension's referenced elements are visible in the view, if the elements are not visible in the view, the the dimension will not display.
Also check whether dimensions are set as visible in the visibility and graphics settings of the view.

One more thing. Are you setting ComputeReferences to true in your geometry options?

Nevermind i see that you are. Reading the code on my phone makes it easy to miss.

I met the same problem as U.

The Dimension was created with sentence "Dimension dim= document.Create.NewDimension(document.ActiveView, line, arry );", but was failed to visible in ANY Views in Revit.

The dimension could be found in the DB and located in any views, but it was invisible in any circonstance.

Have U fixed your problem?

I'm looking forward to your answer.

the code used by boostyourbim gets the (reference) lines  from the familySymbol.

For the (reference) lines of the familyinstance :

		void FamilyInstanceGetLines(Autodesk.Revit.DB.GeometryElement geomElem, out List<Curve> curves)
		{
			curves = new List<Curve>();
            foreach (Autodesk.Revit.DB.GeometryObject geomObj in geomElem)
            {
                Autodesk.Revit.DB.Curve curve = geomObj as Autodesk.Revit.DB.Curve;
                if (null != curve )
                {
               		curves.Add(curve);
                    continue;
                }
                //If this GeometryObject is Instance, call recursive FamilyInstanceGetLines
                Autodesk.Revit.DB.GeometryInstance geomInst = geomObj as Autodesk.Revit.DB.GeometryInstance;
                if (null != geomInst)
                {
					List<Curve> resCurve = new List<Curve>();
					FamilyInstanceGetLines(geomInst.GetSymbolGeometry(), out resCurve);
                	if (resCurve!=null) curves.AddRange(resCurve);
                }
            }
		}

Please refer to this other discussion on fixing a non-visible dimension after copying it from another view:

https://forums.autodesk.com/t5/revit-api-forum/copy-dimensions-from-a-view-to-another/m-p/7226217

Maybe that solution will help in your case as well?
