I know you can use various addins (like Case Extrude Rooms to 3D Mass) to make a form out of a Room element in Revit. However, there is a vanilla Autodesk way you could go about this:
Export a Revit view to Navisworks with all of the Room-related export boxes ticked in the Navisworks Exporter addin
Open / append the NWC in Navisworks
Turn off everything except the Room objects that the Navisworks Exporter created
Export the scene to FBX, convert to DWG, import it to a family, place that family back in the project (using parts of this workflow). Use origin-to-origin linking to get things right.
You could then use the Room 3D element “family” in an Interference Check, to determine what elements exist in Rooms (this would only work for Categories that support Interference Check in Revit).
Jeremy Roh has created some decent tutorial content and shared it on Youtube, covering topics such as Revit, conceptual modelling and Dynamo. One of his recent playlists is embedded here:
I had the opportunity this week to spend a bit of time with Unifi. What is it? Well, in simple terms it is a way to store all of your Revit families in a secure location online. You just batch upload all of your current family library, and Unifi then goes ahead and indexes all of the important family related data. Then, you can do fast and intelligent searches of your entire content library whenever you want to find and load specific families into your Revit projects (using the Unifi addin for Revit).
However, it does a lot more than just ‘store’ stuff. It handles users and permissions in an efficient yet elegant manner, and guess what… because your cloud family library is now globally accessible, you can share it with project team members inside and outside of your domain or organization. You can set up different “libraries” based on their purpose (for example, the standard Revit Imperial/ Metric content can live in one library, while your “Essential” company content may be another, Healthcare families in another library and so forth). Tags can be applied to families, and the search function actually has learning algorithms, so it gets smarter as your team uses it.
What about different Revit versions, you say? Well, after you upload a Revit family from a given version (say 2012), the Unifi servers will automatically create 2013 and 2014 versions for you (automatic upgrading). In this way, there is a single point-of-truth for each family – you don’t get file folders full of different family versions with different functionality (a problem that BIM managers have been dealing with for years).
How many family professionals are in your team or company? Usually there are one or two users who are really at the top of the family tree, and they do your family development, content creation and the like. How can you quickly connect these highly skilled users with the actual day-to-day BIM technicians in your office? Unifi handles that too. Any user can “request” a new family if one doesn’t exist for a particular purpose, and this request is automatically passed onto the family creation people (by Unifi). When they login, they see a list of content requests, and can then handle them in a logical and methodical way. They make the family, upload it, and then the entire team has access to the new content.
Unifi is what Revit content management has needed for some time, in my opinion. You can easily download the trial, upload your content and see if you like it. Many Revit teams are struggling with a core set of challenges when it comes to content; Unifi provides solid answers to many of these questions.
I spent some time with Steve Germano (Director of Product Development) this week, and I was excited to hear about the plans to expand and upgrade the already-compelling feature set of Unifi (including branching out into the Sketchup realm). The development team over there clearly has a good view of what Revit users need, and they are already well on track to provide a solution that could easily become a key part of the Revit content management system in your organization. Additionally, they are listening to the current user base, and continuing to build the feature set with each new update.
If it sounds like these Unifi folk know what they are doing, it might because INVIEW labs is behind Unifi. And INVIEW labs does lots of Revit content development for Autodesk Seek. Are you getting the picture? (This is one of those times that you probably could just stop reading and go get the trial… or) Read on for a brief summary:
Unique, powerful features of Unifi:
your folder structure is automatically tagged onto your content when you Batch Upload it
batch user creation (is very fast!)
tracking of content requests – content creation can be centralised and distributed to key users
Shared Search Keywords (learning algorithm)
Smart Folders / Saved Searches
automatic upgrading of uploaded content (single point of truth for each family)
automatic versioning of changes to families (backup / rollback abilities)
extract any Revit System Family Type from an existing Revit Project and store them in the Unifi cloud – Wall Types etc (this includes complete MEP systems with required supporting families from Routing Preferences)
Steve mentioned that they have no server-side concerns with handling the bandwidth of company library uploads and downloads – the actual storage space is not an issue for them. Its interesting to consider really, because its something that might currently be a struggle for your company: trying to store and backup 100gb of Revit content on your local domain, and mirror that globally between offices, and keep it all in sync. That can be hard. But uploading it to Unifi and getting them to handle it all – much easier from an IT perspective.
A number of large firms have already made a commitment to the Unifi system. If it makes $$$ sense for the big guys, I think it will make sense for SMBs too.
There appears to be some validation in place, that will stop the upload of very bad Revit families (like the Room category family I made a while back) Video here.
You can open the Unifi pane in headless mode (without Revit) by using the shortcut, which will likely be installed to this path: “C:Program Files (x86)INVIEWlabsUnifiUnifi.exe” This will allow you to drag and drop from Windows Explorer to directly batch upload to Unifi without opening Revit.
Give it a go, and feel free to reply via comment to this post or tweet me @lukeyjohnson with your opinions!
Update 1: Some people have expressed concern with having to download their families from the web to insert them into projects. Consider the following points:
you never have to deal with the upgrade screen as Unifi always inserts the native Revit version of the family (a good time saver)
Unifi has a local cache of any family you’ve downloaded (it internally stores the last 50 families you’ve downloaded) so you insert these from local HD anyway.
if you’ve already inserted a family into your project from Unifi, the next time you use Unifi to “insert” that family into your project it actually knows if the family in your current Revit project is the same revision as the one on the cloud, and it simply starts the family place command, it doesn’t actually download again. No reason to as it is already in the project
office to office bandwidth may be extremely expensive compared to internet bandwidth. Multi-office AEC firm CTO’s may prefer the fact that Unifi uses internet bandwidth and not their network bandwidth.
Unifi provides monthly full database downloads for customers, meaning that a rare internet outage is likely a very low risk to affect workflow.
Update 2: If you want to clear your upload queue for Unifi, go to: C:UsersUSERNAMEAppDataLocalINVIEWlabsDiscoverClientSettingsUploadQueue
Close the Unifi Pane, then delete all of the files in this folder. After restarting Unifi, your upload queue should be clear.
From a LinkedIn discussion: normal .ifc file from Tekla with the rebar option ticked and imported it into MicroStation, from there I exported a .sat file of the rebar and inserted it into Revit. Of course this means you can’t modify it in anyway but if all you need it for is to cut sections then works quite well.
I thought it might be useful to set up a shared folder to allow Navisworks users to upload, download and share resources. The idea here is that lots of Navisworks resources (as listed below) can be exchanged and re-used on future projects. Why should we all keep reinventing the wheel?
Only invited users can upload, while any user can view and download the content. Note: if you are an uploader, keep in mind that this will be globally accessible, so you need to be aware of any IP considerations that may apply. At this point, I’m considering this to be “open source” (with associated licensing conditions). Additionally, I am keeping the guidelines to a minimum, just feel free to share something if you think others could make use of it.
