I, for one, don’t want to wait three years to make that happen. That’s why we’re all here on Revit ideas right? So that we can get you the improvements you need. We’re excited that we are able to get these new features to you as soon as they are completed. These changes are shipped as part of our point (previously R2) releases. I also want to point out that we already make an effort to identify and work on improvements that don’t require a format change. We often hear feedback that we don’t improve the product fast enough unfortunately this would aggravate, not alleviate the problem. If we had to wait 3 years to get significant enhancements you, it would also mean we would it would be another 3 years before we could make further improvements/corrections to features.

For example, the ability to have OR in filters could arguably be reflected as one format change, but that change could impact hundreds of views and sheets. This also doesn’t account for the fact that one change can have a huge impact. So, on average, there are over 10 format changes per development day. Comparing our development build to the 2017 file, there are about 3,000 changes to the format. I took a quick look and by my estimation at least 14 of the top 20 ideas on this forum would require changes to the file format. To be quite frank, freezing the file format would significantly hamper the speed of Revit development as the majority of Revit features require changes to the file format.

There are two ways we could approach the problem: freeze the file format or add converters that transform new data to old data to recreate the old file format. It is quite simply an exceptionally difficult (impossible?) technical challenge, which, were we to embark on fixing it, is unlikely to fully deliver on the expectations and experience that you deserve (more on this later). If backwards compatibility was an easy thing for us to do, we would do it in a heartbeat because we understand that this would enable workflows that are a true challenge today. Further, there is no motive that is not expressed in this post. Despite what a few posts here suggest, this decision has nothing to do with how we sell our products, nor is it a strategic move on our part. “Can I save my Revit project for an older version” is the probably one of the most asked questions about Revit (along with “When do we get Revit for Mac” and “How can i override a dimension”) – Sasha Crotty, Revit Product Manager, posted a very nice explanation over at Revit Ideas as the explanation why this won’t be implemented:įirst off, let me say that this is not a decision that we take lightly.
