DimensionSegment /Dimension Segment Array

Anonymous — Fri, 27 Sep 2019 17:15:58 GMT

I am familiar with the process to generate dimensions by creating lines and adding references to an array. However, I have been attempting to recreate an ordinate dimension string as seen in the image, where it is a single string with multiple references. From using Revit Lookup, it appears I need to construct a DimensionSegmentArray and Append it with a DimensionSegment. I've attempted to create lines and use those, but get an error to create "DimensionSegments" instead. I've searched hours for a solution to this, but I am apparently missing something.

How would I construct a "Dimension Segment"?

Would I have to create a NewDimension for each segment, then append those to create another, longer dimension? If that's the case, then how would the number of Reference Arrays work in the longer NewDimension?

Using the code below, I was able to generate a single dimension string. How would I be able to generate a dimension string with multiple references and dimension segments (as seen in the image below the code and in the first post)?

When I Append multiple references to the ReferenceArray, I get an error saying "Expected DimensionSegment, got Line" for the dimension transaction. I also generated an unboundline to see if that woul work. A solution to this would be a huge help.

P1 = edge.AsCurve().GetEndPoint(0)
P2 = edge.AsCurve().GetEndPoint(1)
        
dimensionLine = Line.CreateBound(P1, P2)

dlEdRef1 = edge.GetEndPointReference(0)
dlEdRef2 = edge.GetEndPointReference(1)

edgeRefArray = ReferenceArray()
		
edgeRefArray.Append(dlEdRef1)
edgeRefArray.Append(dlEdRef2)

tt.Start()
dim = doc.Create.NewDimension (view, dimensionLine, edgeRefArray)
tt.Commit()

I answered my own question in the post above after a bit more exploration.

Segments got created automatically as reference planes were sequentially added one after another to the reference array.

XYZ p1 = new XYZ(10, 10, 0); XYZ p2 = new XYZ(10, -10, 0); XYZ p3 = new XYZ(-10, -10, 0); XYZ p4 = new XYZ(-10, 10, 0); ReferencePlane refplane1 = doc.FamilyCreate.NewReferencePlane(p4, p1, cutVec, uidoc.ActiveGraphicalView); ReferencePlane refplane2 = doc.FamilyCreate.NewReferencePlane(p3, p2, cutVec, uidoc.ActiveGraphicalView); ReferenceArray raD = new ReferenceArray(); ReferencePlane refplane3 = doc.FamilyCreate.NewReferencePlane(new XYZ(0, 0, 0), new XYZ(1, 0, 0), cutVec, uidoc.ActiveGraphicalView); doc.Regenerate(); raD1.Append(refplane2.GetReference()); raD1.Append(refplane3.GetReference()); raD1.Append(refplane1.GetReference()); Line LineD = Line.CreateBound(new XYZ(p4.X-0.5, p4.Y , p4.Z), new XYZ(p3.X-0.5, p3.Y , p3.Z)); var dimD = doc.FamilyCreate.NewLinearDimension(uidoc.ActiveGraphicalView, LineD, raD1); DimensionSegmentArray s = dimD.Segments; s.get_Item(0).IsLocked = true; s.get_Item(1).IsLocked = true; dimD.AreSegmentsEqual = true;
