I try to model post tensionning tendon on Revit. I have the idea to extract from Autocad 3D curves of tendons profile and transform this to a revit element. I have succeded to convert 3D line to Revit model lines (you can see that on the picture bellow). Now I have no idea to convert these line to a family instance (and which family ?). I think pipes family are flexible enough to do this work in the first time. On a second time I want to create a family based on Generic model adaptative template.
Have you an Idea to do that ?
