Revit

in the CAD.CurvesFromCADLayers node

There is an input: LayerNames

You need to feed it the name (as a string) of the AutoCAD layer that contain the curves

Hello, thanks for the answer. But I tried that, however I still haven’t resulted, and it also has any errors. I still don’t know what it can be. Would it take the CAD file to be all clean? With only the layer of the walls? Because if so, it doesn’t make much sense, it doesn’t speed up the work.

Can you tell us which node gives the error? Also did you fill in “Externa” correctly?

it also seems you are picking some longer Curves out of a list but not really merging Curves etc.

Can you supply the AutoCAD file with this script? I can then take a more comprehensive look

Good evening everyone!
I copied Alban’s plan, but unfortunately I got a problem with the GroupByParallel node. It doesn’t find the DWG lines, i only can see null. Can you please tell me what I’m doing wrong? I can’t find the error.

Hi,

The DynamoIronPython2.7 package version 2.5 must also be installed when using custom nodes written in Python.

Quick point of clarity on this: the nodes must be be installed if the code was written using the 2.7 engine.

Thank you for your help, it almost works. The only problem is that no center line has been formed and the wall has built up on the outer line of the DWG.

Unfortunately I cant upload my .dyn file.

I also don’t understand why I have to set the code block for group by distance to 0.4 for it to work. actually my wall thickness is 0.2.

Thank you all!

I can’t fine the Flatten node, I found a List.Flatten node.
I also did not find a Project Units mm node, do I need it?
I also did not fine Levels.LevelsAbove.
I’m in imperial units and working with Revit 2022.

Hi,

This topic is 6 years old and is already solved.
Please start a new topic.

Use the Adjacent Levels custom node from the Genius Loci package.

I did start a new topic. There are several other nodes that are not found in Revit 2022 “Flatten” Projet Units" to name a few.
