Sharing a pretty disjointed/funky workflow today that I came across and put a few things together for recently - checking Revit file versions using a Python IDE and no need for Revit itself!

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

@AussieBIMGuru Год назад

Thanks for the kind words, and you are welcome!

@LSArchirects Год назад

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

@AussieBIMGuru Год назад

Ah yes I know the pain as well!

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 Год назад

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

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 11 месяцев назад

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 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 11 месяцев назад

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

@miapepe 2 месяца назад

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 2 месяца назад

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

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 11 месяцев назад

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.
