I am trying to draw a detail line on top of a wall by using dynamo. I can get wall center line by using element.getlocation. But when I tried to connect this curve to DetailCurve.ByCurve node, Dynamo stopped working.
I tried to convert this curve to modelline by ModelCurve.ByCurve and it works fine.
Also I tried to create curve originally from dynamo(set 2 point and connect them as a line), and test DetailCurve.ByCurve node, it also works fine.
I figured it out. I am using Revit 2019. The Roombook Areabook Buildingbook for 2019 adds-in seems to be conflict with this components. Also it will significantly slow down Revit 2019. Hope to be improved in the next version.
