How would I go about editing an existing floor/ceiling boundary? Rather than creating new elements to follow a defined polycurve, I want to update the sketch of an existing element. I’ve got as far as using the Collect.ElementSketch node from Springs, but I’m not sure how to write the info back to…

This might be a good place to start with modern Revit builds, as the sketch edit api is now exposed. [image] Sketch Lines - Edit, Copy, Paste Modified version here: modify sketch to given lines - share out.dyn.dyn (22.2 KB) Works like this: [image] First use: Copy li…

[image] I want to edit the sketch of an existing floor or slab Revit Btw we do have partial control over an element’s sketch, but extracting the sketch curves is costly. Once we get the correct sketches, we can move them around: [image] delete any internal loops: [ima…

Thanks @Vladimir , I tried this method and got this far: [image] It works perfectly for floors that have the same number of edges, however in the above example the source floor has 6 edges, which causes issues. Any suggestions? Also, thanks @jacob.small , but I fear I might have been using your ex…

[image] dan.buckingham: Also, thanks @jacob.small , but I fear I might have been using your example incorrectly as I couldn’t get any results. I’m using Revit 2023 & Dynamo 2.16. No one can tell you if it is being used right as you haven’t shown how you are using it, however you may have to ed…

This is the error I’m getting faces with. PythonEvaluator.Evaluate operation failed. Traceback (most recent call last): File “< string >”, line 50, in < module > exception: Illegal attempt to modify element. Reason: EditModeMgr element modifiable checker

I cannot duplicate the issue you’re seeing. Can you post your rvt and dyn with the selected source and target elements?

[image] rac_basic_sample_projectDB.rvt 2 files sent via WeTransfer, the simplest way to send your files around the world Revit 2023, Dynamo 2.16

Working fine for me - what issues are you seeing? [modify sketch]

So I’ve just reopened the rvt file and the dyn script, and it’s now working perfectly! Sorry, no idea what was cause that error with the final python script previously. Thanks for your help!

Hi @jacob.small , I’m expanding on this idea, and looking to iterate the process for multiple floors. The Sketch Plane script is working perfectly when the input is a single floor, but it’s throwing up the following error when multiple floors are input: PythonEvaluator.Evaluate operation failed. Tr…
