Insert line based family

[Anonymous]

Hello. I want to insert line based family into project. But there is exeption "This method is only applicable for detail families". I used "Generic Model line based.rft" for created family. What is the problem?

MyFamilySymbols = FilteredElementCollector(doc).OfClass(FamilySymbol).ToElements()
FamSymbol = 0
for famS in MyFamilySymbols:
    if famS.FamilyName == CableFamilyName:
     FamSymbol = famS
     break

TransactionManager.Instance.EnsureInTransaction(doc)
XYZforFam=XYZ(0,0,0)
XYZforFam2=XYZ(1000,1000,0)
newLine = Line.CreateBound(XYZforFam,XYZforFam2)
newobj = doc.Create.NewFamilyInstance(newLine, FamSymbol, doc.ActiveView)
TransactionManager.Instance.TransactionTaskDone()

try to use curve instead

NewFamilyInstance Method (Line, FamilySymbol, View)

Hey,

Based on the error you have and according to the documentation, the method you are using (the one that takes a Line, FamilySymbol and View as argument) is used to add a detail family instance on the document.  You must use a different Template to create your Family, the one called Detail item line based.rft.

Alternatively, you could maintain your family and use other arguments with the same method. There is an option that takes Face, Line and FamilySymbol.

I think both alternatives should work.

Good Luck!

Thank you for response. I think I have to try another overload NewFamilyInstance(Curve, FamilySymbol, Level, StructuralType)

I want to place my family on level.
