Love the explanation and how you delved a bit further into the API for things that aren't just on the surface like others do. Also thank you for touching on filters, it's definitely a broad topic but another perspective is always informative.
Thank you! I will eventually cover filters in more depth, but for now you can check my guide for FEC and Filters with examples and explanation if you want to learn more about them.
This is super helpful! I went and made some collector functions based on this code and added them to my lib file I started. But you gotta let me know how to put a list in multiple lines like that when you are making you category list.
Thanks, I hope I understood your question right. It has been a while since I made the video. 1️⃣In python if we break a line and leave '\' in the end, then python reads next line as part of the current line. e.g. FilteredElementCollector(doc).OfClass(Wall).ToElements() FilteredElementCollector(doc) \ 👈 .OfClass(Wall) \ 👈 .ToElements() Usually IDE(at least pyCharm) adds this automatically when you break the line. 2️⃣ However, if you meant lists, then we don't need this sign because lists are covered with square brackets on both sides, and python knows. There you are free to break it into multiple lines. Just keep track of commas. e.g. [1,2,3,4,5,6] [1, 2,3, 4, 5, 6] I hope I answered your question. If not feel free to expand your question on that. Happy Coding!
Glad you liked it! Unfortunately, I have no time for that at the moment. But I will have a phase when I will write more guides and update this one along the way as well. P.S. If anyone know nice E-Book online writer let me know. I need something that supports code snippets, so it's not images but an actual text that can be copied. So far I think I might do it in Figma due to higher customizability, but that's not the final decision.
What I really need is to understand how to pass a list or filtered elements into a dialog like the PyRevit "Select From List (Single, Multiple)" dialog. Would also like a video on how you make the dialogs for your EF Tools commands.
Noted. I have a video in mind for pyRevit input forms, but I am quite busy with many other video ideas for now, hopefully get to that one in a few months. I create my GUI with WPF, and it's quite advanced from my opinion. I will eventually try to make some tutorials on the topic, but I will leave it for the end, I try to focus on more basic concepts for now.

I have been struggling with selecting elements in a given view that is both in the current model and in linked models. Does the filter element collector work for linked models as well?
Usually, we need to provide doc variable of the project we want to get our elements. if you want to get Linked elements, then you need to find and pass doc from linked model. I am not sure if we can provide linked model and then provide a view from another project. I believe there should be a way to achieve that but I haven't tried to get it like this yet.
@@ErikFrits much appreciate response! I am interested in programmatic approach to grab elements from current doc and all visible linked elements as well…perhaps a topic of a future video if you ever are able to crack the code ;) 🙏
Hi, erik! i have seen your tutorial and by the way i have learned a lot, thanks! i have had some difficulties to understand the VARIABLES and i did not understand when you used active_view = doc.ActiveView. Do you know where i can learn more about it?
You might need to check some python basics course. CS50 Introduction to Python by Harvard is a popular free course on edx.org platform. I would recommend start there
I haven't worked with rebars in Revit API, but usually there is a property 'Host' that returns an element. Have a look inside of Revit Lookup For example: if I have a variable window.

Hey Erik, I really learned a lot from your videos! I am really stuck at the moment with using a doc-changed hook, it seems to be impossible to use transactions with it (edit a parameter). Maybe you have some knowledge about this?

@@giancarloarciniegas8466 you can definitely make this with C#, but with python I don't think there is a ready solutions for that.

Not an easy. Try searching in Google, maybe someone has solved this problem already and shared solution.
@ErikFrits based on what I did so far with linework it looks like it's possible to get everything I need for linework with importinstance. There is nothing for text however. I started implementing what it looks like everyone else does, export to dxf and read that file for text info.
Hey@@ErikFrits , I'm here again. Is there a way to retrieve all structural and architectural elements, or do I have to specify all the structural and architectural categories and use the FilteredElementCollector method?
@@FelanaDiamondraRANDRIAMADISON You still need to use FilteredElementCollector. You can use .OfClass or OfCategory to get desired elements. If you decide to use OfClass, be aware that certain classes are located in discipline namespaces like Autodesk.Revit.DB.Architecture, Autodesk.Revit.DB.Structure and others.

I might write a newsletter episode about that one 😉

Great video, if you could make one's about filters it would be perfect, thank you Erik
Thanks!
I have plans for it, but at the moment I need to cross many other things from the to-do list ;)

@@ErikFrits Thank you, Erik
Great video. I have a question. How to set a value parameter from a host to elements that it contains? For example, from a beam to rebars. Thank you.
I haven't worked with rebars in Revit API, but usually there is a property 'Host' that returns an element. Have a look inside of Revit Lookup
For example:
if I have a variable window. I can get its wall something like this:
wall = window.Host
Or if you have a list of windows and you need a list of hosts:
walls = [window.Host for window in all_windows]
If you new to parameters in Revit API, I have another video which will show you all you need to read and set parameters ;)
