First time I hear about that one. WPF_Base is a class that is used for all my UI Forms so it's confusing to me. - Can you tell me what Revit version did you use? - Also, have you tried reinstalling? Sounds to me like you are missing code in your installation.

@@ErikFrits I use Revit 2023. Reinstall Revit, pyRevit or the extensions?

​@@renatogheno Delete and Reinstall EF-Tools through pyRevit extensions menu. I use 2023 as a main version, so that should be the one with the least bugs :/ Let me know if you still get this error, I will need to check what's going on

@@renatogheno I can see that WPF_Base is present in the extension on GitHub, so you shouldn't see the error No module named WPF_Base... github.com/ErikFrits/EF-Tools/blob/main/lib/GUI/WPF_Base.py I would appreciate if you could send the full error message if you get it again.

Thank you for kind words and glad that you read newsletter too! Oh wow, I keep getting a ton of request on the WPF lately. It's certainly on the list to do one day, but I need to brush up my skill again before teaching. Happy Coding!

@@ErikFrits Yeah It was me aswell per email :D (Bram) But yeah, WPF is the key to making, not just handy tools, but awesome looking ones aswell. Im getting the hang of python for revit specfically. Want to make the tools we make into our "in-house" style. And most of us make these tools in our spare time, because we are way too busy during workdays. Nowadays AI tools are a big help, like chatgpt, but I wish to understand it myself.

Oh makes sense, but I was getting even more request on WPF. Oh yeah, AI is a big helper. I've made little test with WPF, and it can also be useful for creating forms. But Binding the data to python code would probably have to stay manual.

Oh yeah, WPF is very requested but there is a lot to prepare for it first 👀

Hi, Happy to help! I haven't looked how to attached/detach walls to other elements with Revit API. Haven't had an idea for such tool yet 🤔

Also can you please tell me if it would work for central - local network model vs ACC cloud model?

Happy to help! Any particular tools in mind for the requested topics?

Check out EF-Tools installation Guide on CZcams 😉 czcams.com/video/q0zbdyyBIo0/video.html

My pleasure!

Hi, You can start with the free E-Book (check link in description) And there are plenty of videos on CZcams too! Focus on python until you are comfortable, then dive into Revit API

Thanks alot sir​@@ErikFrits

Thanks for suggestion. Haven't looked at constraining elements yet, but I will add it to the list.

You might need to explore events triggers. The event you mentioned: This event is raised when Revit is just about to reload latest changes from a central model. I would recommend to start very simple and just make some print statement when it's triggered. If you can't get it to print, then either your event is not triggering, or you have an error in your event handler and therefore nothing happens. As I've mentioned errors happened during the events won't be shown to us, so we need to make sure our code is working good and we handle all the errors ourselves.

@@ErikFrits Thanks for the reply! I tried and tried and couldn’t get that particular event to ever fire. However, I was able to use WorksharedOperationProgressChanged event. It has a property called “ReloadLatestFinished”. The event triggers a bunch of times during reload latest, but you can track the status using that property.

🙌 First come - first served ;)

Leuk, maar naar het nederlands vertalen is voor codeertaal wel een ramp. of bedoel je alleen de # teksten? Nice, But translating to Dutch is horrible... or do you mean only the # texts? def SkipAllAboveTekst(): :D

Glad you found them useful! Happy Coding!

Yes, UnitTypeId was introduced in 21 or 22. Before that we had to use DisplayUnitType Enumeration for the units. www.revitapidocs.com/2019/7d3d3306-a4c2-c577-0aeb-cca42d6cfd2f.htm

Awesome! I hope it will save you a lot of time ;) Happy Coding!

JavaScript?

python? 😁

Hmm that's strange. Probably there was a mistake somewhere. 1. Is it named 'icon.png' ? 2. Is the size less than 96x96 px? 3. Have you reloaded pyRevit ?

@@ErikFrits Found it ! i rename the file as 'icon' with no '.png' at the back. Cause the file are already in PNG format. Thank you for your help Erik

@@luqmanghani8047 Ah so you had file extensions hidden by default. Glad we found the solution ;)

It's a great feature!

Happy to help

I haven't done it for floors, but it's possible to do. I'm just not sure how many people might need it 🤔

Thanks ! I need to add dad jokes 😂

I don't think it's an error if you see "unused import statement" pyCharm IDE monitors unused variables, imports and other things to notify us that it might be a good idea to clean it up. Does python autocomplete work if you keep writing further? (os.path.join() e.g.)

@@ErikFrits Yes the autocomplete seems to be working thanks.

Great Suggestion, Max! I'll look into that, it's a very requested topic about external packages. Meanwhile, you can try using sys.path.append to manually push the path to where your numpy is located. Maybe it will force it to find the right path.

Happy to help!

Hi, yes I provide students discounts too. Write me to support@LearnRevitAPI.com , and we can talk about

I tried MIT when I started with python many years ago. It was good but it's a much longer course and it also covers more ground about computer science in general. C# and C++ definitely have a bunch of advantages over python: Execution speed, protected source code, better handling of .NET features.... But python is by far easier and quicker to begin with and it's also possible to push it really far to create advanced tools. My goal is to help AEC expert to begin coding, and python is much better choice since it takes less time to begin with. And people can always switch to other languages much easier. And Revit API logic will pretty much stay the same. C# and C++ requires you to dive much deeper before you can start make your first Add-Ins so therefore I focus primarily on python for beginners. The good thing about programming - is that all the languages are similar. The computation logic stays the same, we just need to express it with different words and additional symbols (syntax)

Happy to Help!

Happy To Help! Did you get any errors or where did you get stuck with your problems? - What was the problem with generating schedule? - For exporting TextNotes in CSV you can use csv python module. You just need to get and structure your data and then export in a csv format. ChatGPT will be able to help you write the code if you never used csv package ;)

Happy to help!

Hi, Thanks for suggestion, I've added it to the list ;) In my experience, I actually liked keeping pyRevit extension on the server so everyone points in the same folder, so I only needed to update it in 1 place, instead of updating it on each machine individually. But since you use VPN and pyRevit scripts take long time to execute, then it might justify it.

I also found Chatbot Arena a very interesting resource! So easy to test different models quickly without making lots of accounts

Thanks!

You mean placing nested line-based families inside of a family? Can you give a bit more context on the goal

@@ErikFrits Yes, exactly placing a line based family on the default level or reference plane in the family environment. I have alot of line based families which i want to place in the another family (Generic model containing all line based families). All these lines lines represent walls for repetitive floor plans in one project and across different revit files. in that way i can change it one time and reload it into all the projects if there are some changes in the floorplan. The problem is that the familyinstance.bycurve node works fine in the project environment but doesnot work in family editor environment. i posted it in the dynamo forum and someone suggested to use this method "NewFamilyInstance Method (Reference, Line, FamilySymbol)" but still its not working. I used chatgpt to convert the c# example to python and tried it but didnt worked for me. Thanks. I am a dynamo user and now i am starting learning Revit API and Python. Your videos are really helpful. Thanks for that.

Зравствуйте. Запуск курса планируеться очень скоро. Можете мне написать на support@LearnRevitAPI.com Так будет удобнее написать когда я узнаю больше об оплате с России.

Hi, The next course launch is planned very soon(in 2-3 weeks) and it will stay always open after that. Sorry for the late reply. P.S. If you want to get an immediate access, write me to support@LearnRevitAPI.com ;)

Thank you a lot Daniel!

Hi, Do you mean venv folder after you created an interpreter? venv folder is created when you make your Virtual Environment (venv). It's a default name but in the tutorial I think I named it differently. Also I've heard that people had issues with pyCharm 2024 for making Revit API Coding environment. But once they downgraded to pyCharm 2023, they managed to make it work. Maybe this is part of your issue as well.

Merci!

Happy to help ;)

if someone is wondering what the problem was, then I named the file doc-changed instead of doc-updater

Glad you solved the issue🙏 Naming of the hooks is important!

Hi Gilberto, 1. Disallow Unpinning IUpdater is not the best option here in my opinion. Instead of that you can subscribe to the event of Unpinning elements, and then check if element can be unpinned based on your rules. Then if it shouldn't be unpinned you can prompt a message to the user and cancel the 'unpin' command. I've made a tutorial before that one where I blocked "Import CAD" button in Revit and put a password on it with a command hook. here is link: czcams.com/video/tfEQAv36EaM/video.html 2.Monitor Element Deletion I might also use another monitoring events here. Monitoring other events allows you to stop the execution of the command that caused the Event Trigger, and also it can be enough to write something to a reporting file. The only downside of using other events is that we can't make changes in Revit Projects. IUpdaters are useful when you know you want to add Extra changes to the model. Otherwise they might be an overkill as they are a bit trickier Hope it helps Happy Coding!

Happy To Help, Oscar!
