A structural framing element is attached to a wall whose Structural Usage is set to Non-bearing. This means that you have used a structural element such as a beam and it is attaching to a wall whose structural usage is set to Non-bearing. The following table lists the automatic Structural Usage settings for beams, based upon the elements in which they are being connected. There are a couple of different methods to correct this problem, each with pros and cons. The method used would be dictated by a number of factors, including determining if the structural elements(s) are truly structural elements or some type of faux treatment. #1: Change the Structural Usage of the Wall from Non-bearing to Bearing by selecting the wall and bringing up the Element Properties dialog and changing the Structural Usage to Non-bearing. One of the downsides to this is if you are working with a structural engineer that using Revit Structure this wall will appear as a Bearing wall. If yo...

In case you haven't started reading it, Phil Read formerly of Autodesk Consulting has joined HNTB Architecture and started started a Arch | Tech blog. His latest post is on the weakness of the current Revit Warnings system. I used to be one of those users that didn't concentrate too much on warnings, until I started working with Daniel Hurtubise . It took Daniel all of a half hour to show me the importance of addressing warnings immediately. Yes, I know that is not always possible, but it is a good practice. (If you are a non-believer, send Daniel an email and I am sure he will provide you with a demo). Since then I have been working with Phil and Autodesk Consulting (and yes they still have some assume talent there) on addressing warnings. While we have been documenting many warnings to provide the user with greater insight on how to correct them, the ability to access and track warnings has been lacking. When Phil joined HNTB, one of the topics I was hoping would be address...

With the help of a formal colleague and friend Daniel Hurtubise (see his French RevitIt blog) we are documenting a number of Revit Warnings. But the question I get both at work and via this blog is, "What's the Big Deal with Warnings". Which is usually followed by, "They don't prevent me from doing something and my sheets still print". So, I think it is important to discuss how important it is to address warnings sooner than later (or not at all). I think the first and foremost reason to address warnings is that they can have a huge impact on the file size and performance of a project. This is especially true with warnings that have to do with overlapping items such as walls, room separations lines and duplicated instances. The first time you encounter a warning is really the best time to address it. So if Revit thinks you are doing something it does not like, Revit will throw up an alert explaining what it thinks you have done wrong. I'll be the first ...

This can usually happen when are are picking geometry from an AutoCAD file. Revit will report this error when a wall is drawn at an angle at a with a fractional degree, such as 95.1 degrees. To correct the problem, either redraw the wall or change the angle. You can sometimes verify the angle by creating a 3-4 decimal point dimension style.

This means that you have a wall that is attached to a floor, roof etc. but the wall does not physically attach or touch the roof or floor. This warning can generally be corrected by “detaching” the wall from the floor or roof. Special thanks to Daniel Hurtubise, aka the Revit Warnings Nazi for his help on documenting Revit warnings.
