Hi, i have a List of Points(3d) and now i just want to create an ID for every Point. I know it has something to do with Element.setsParameterbyName or FamilyInstancebyPoint…but i can’t figur it out. The ID should be like, 1,2,3…1000 or Point1,Point2,…,Point1000. Can someone help me with that?

It depends what you want. The simplest is GetKeys, which is an element position in the list. But the number will not necessarily stay the same for each element if you run the Dynamo graph several times [image]

Thank you for that Andrew and Yna. I will try it and post Results.

Well, i got a Warning: [Internal error, please report: Dereference of a non-pointer] at Element.SetParameterByName and [FamilyInstance.ByPoint failed.Value can not be null.Parameter name: familyType] at Family.InstanceByPoint. I think i need the FamilyInstance to get the points from Dynamo to Revi…

The rule is quite simple: nodes won’t work if you don’t feed them with what they ask for, which means that you can’t enter a Parameter value into an Element input and neither an Element into a FamilyType input. In general, requirements are written in the description of the node. More explanations he…

@Hannes What exactly do you want to achieve ? Points don’t exist by themselves in Revit, unless within a topography, adaptive family etc In Dynamo, you need to do something with the points, such as creating geometry or inserting a family The screenshot is chopped off- but it doesn’t make sense- …

The entire workflow would be too big for a picture, so I had to cut it Im trying to get points out of an xml file. Make lines out of it and get it into revit. here is my upadate: now i got a family:) and a id for every point. (I thought that would be necessary to get the points in Revit) [image] …

I’m not sure- I am not in front of a computer with Dynamo, but you are feeding a line into the DetailCurveByCuve node, which does not look right to me (I think it needs to be a curve) Do you specifically want detail lines in a certain view rather than model lines ? Andrew

Hello, curves are something special in Dynamo: “Lines are the simplest form of Curves” (see here: http://dynamoprimer.com/en/05_Geometry-for-Computational-Design/5-4_curves.html ) but as usual it must be tested…

he thx for help! I don’t need specifically detail lines. All i want is to get my Lines (From StartPoint to EndPoint) to Revit. So i tryed DetailCurve.ByCurve and DetailLine.ByCurve. With the same result: Error for two Elements (Lines) - they can’t connect. If model lines stay permanently in revit…
