What did you do?
I attempted to reduce the length of a curve using the Curve.ExtendStart node in Dynamo for Revit 2024 and 2025. However, Dynamo does not allow negative values for the distance parameter. As a result, I received the following warning: "Curve.ExtendStart operation failed. Failed to extend Curve: NON_POS_LENGTH -- length negative or zero."
What did you expect to see?
Curveextend_2024-06-27_03-24-57 In Revit 2023 and earlier versions, I was able to reduce the length of a curve without encountering this issue.
