What is a good way to place a workplane based family, for example onto a reference plance? I can find only nodes that require a face as the host. Place by face would mean that I first have to create a Revit element, just for its geometry, then retreive the correct face, then place the instances and…

So, the answers: -To place a workplane based family use FamilyInstance.ByReference from Genius Loci -Error code 5: dont know what it means exactly but my mistake was feeding a vector which was not on the workplane as a direction. The direction given should correspond to the family’s internal posit…

Furthermore, I am looking at FamilyInstanceByFace. When you feed it a plane instead of a face, it says it needs a Dynamo Surface [image] If you feed it a dynamo surface, it says it needs an ElementFaceReference [image] If you feed it an ElementFaceReference it says it needs a Surface :frowning: …

The node needs the face reference of the geometry surface. It’s confusing. I’d ignore the node for now. Make sure the original python code works for a single instance first. It should, that method has not changed. If it does, then you can move on to handling a list of inputs. I would recommend zipp…

Hi, If you want to place instances on a reference plane, the FamilyInstance ByReference node of the Genius Loci package will work.

@Alban_de_Chasteigner I tried your suggestion but im confused. The description says it can handle a reference plane: [image] But the parameter description says it needs a face from an element. [image] I have tried with feeding referenceplane but then an error comes. [image]

You need a Autodesk.Revit.DB.Reference in the input reference. Use the Element Reference to obtain it from the reference plane.

Thanks for the advice @Alban_de_Chasteigner . At first I got it to work. As you can see from image below. [image] But then … I messed up again X), and now it doesnt work anymore. And I get the exact same ‘Error code 5’ with the Genius Loci node as I got with my own code in my post above. So the…

Here is a reproducable sample (dyn and dummy are attached). What is wrong with this code? [image] Dummy.rfa (408 KB) error.dyn (22.0 KB) FYI 2 nodes are from the GeniusLoci package: [image]

I believe I have it. I am a dumbass and had my vectors mixed up…

FYI 2 nodes are from the GeniusLoci package:

Do we have any nodes to edit workplane
