NewLinearDimension input not met

[crapai]

I'm trying to create a dimension between a reference line and plane and I'm getting and error saying input are not satisfied. It looks like from the API that I am meeting everything. What am I doing wrong?

Here is the error on line 36 below:

Exception: One of the conditions for the inputs was not satisfied. Consult the documentation for requirements for each argument.

t = Transaction(doc, "pyRevit - Create Reference Plane")
famMan = doc.FamilyManager

famMan.AddParameter("Label_Dim_LeftCorrection", ForgeTypeId(), SpecTypeId.Length, True)

lineSymbolVerticalCenter.ChangeToReferenceLine()

# Create Dimension
ra = ReferenceArray()
ra.Append(refSymbolAnchorLeft.GetReference())
ra.Append(lineSymbolVerticalCenter.GeometryCurve.Reference)
dimline = Line.CreateBound(XYZ(-3, -1, 0), XYZ(2, -4, 0))
dim = doc.FamilyCreate.NewLinearDimension(cView, dimline, ra)

Testing to add the dimension type even thought here is a method that uses the default dimension and no luck. I printed out all the input to check if it was all there but nothing.

Are you sure the line used to create the dimension position is perpendicular to the reference line and plane?

[crapai]

I fixed that a bit ago but still getting this error. The line should now be -3, -4 to 2, -4. I've also tried switching the points and lowering them, even though I don't think that would do anything.

t = Transaction(doc, "pyRevit - Create Reference Plane")
famMan = doc.FamilyManager
#dimType = FilteredElementCollector(doc).OfClass(DimensionType).
dimTypeId = doc.GetDefaultElementTypeId(ElementTypeGroup.LinearDimensionType)
dprint(dimTypeId)
dimType = doc.GetElement(dimTypeId)

Turns out the references weren't working because they didn't exist due to them not being committed. I ending up using subtransactions and regenerate to get the lines to be committed before adding the dimension.

Nice, gratz for solving. For Document.Regenerate() ,I know that Transactions automatically regenerate the document, but not sure if subtransactions do that also. Maybe you could try removing it, would shave some milliseconds 😂
Anyways, good job

[crapai]

Originally didn't have the regenerate. So, I had to add it.
