Read Revit file versions using Python (without opening Revit)!

[@user-me9qt4ux3m]

People don't say it often. But you are one of the best..since years. Thank you.. thank you and thank you.🙏👍

[@AussieBIMGuru]

Thanks for the kind words, and you are welcome!

[@LSArchirects]

Perfect timing to help with the latest 2024.1 schema bugs!…. Which I may have upgraded a couple of projects too… 🤦‍♂️

[@AussieBIMGuru]

Ah yes I know the pain as well!

[@costas92]

I actually created a very simple script that you can run in powershell that will do the same thing and export everything to an excel file, it does so by scanning the actual code of the file, similar to opening it up in Notepad, and searched for a particular string. Unfortunately this only works with rfa files but it's been a great help in cleaning up our content.

[@AussieBIMGuru]

Nice one! Yes I believe the OLE/binary option is the only safe way to deal with larger files like rvt.

[@miapepe]

sorry for stupid questions, do you have this in opensource? i need to extract information, such as components, sizes and materials from .rvt file in python

[@AussieBIMGuru]

Most of that information is not possible without cracking the Revit file format/ole. I believe this has been achieved by some companies who sell this as software, but is well beyond what I know how to do with a raw Revit binary interpreter. This article summarizes it: thebuildingcoder.typepad.com/blog/2010/06/open-revit-ole-storage.html If you mean my code, this is on my github: github.com/aussieBIMguru/Misc/blob/master/ABG_260628_RevitBuilds.zip

Great video! Is it possible to access the actual revit database this way to batch check the views' properties or some built-in parameters of some revit elements?

[@AussieBIMGuru]

Unfortunately not using Revit API etc. Maybe look into this company which reckons they've cracked the code on Revit and offer a software solution for it: www.opendesign.com/products/bimrv

[@KervinCalero]

hmm, I came accross some project files that have built: [wrong year or last date modified] and format: [correct year] 😞, is there a workaround for parsing the binary file in this case? Thank you

[@AussieBIMGuru]

Yes get in excess of the needed characters and then process the string afterwards to detect the syntax in the alternative case. Basically ask the binary to decode more than needed.

I actually have a question that's not related to these video, When i Add formula to the parameters using instance parameters, there would be an error, it said that the family is a type driven family and connot be driven by instance parameters. How do i fix this and turn it into instance driven parameter.

[@AussieBIMGuru]

Type parameters cannot be driven by instance parameters. To work around this your driven parameter needs to be changed to instance. If it is an inbuilt parameter you can do this by using it in a dimension/constraint and selecting it, then toggling the Instance tick box in top ribbon.

Thank you

[@PANDURANG99]

What if my model stored on cloud?

[@AussieBIMGuru]

At that point you would need to look into forge unfortunately. Dynamo isnt built to work with cloud files.

[@PANDURANG99]

@@AussieBIMGuru for forge there is big learning path. Administrative control, forge paid subscription etc

[@AussieBIMGuru]

Yep there sure is. No way to sugar coat it though, if you want to automate in ACC/BIM360 it's your only option really.
