The ability to create groups of Steel Columns, Beams & Connectors. In a given design you are likely to use a group of elements repetitively at various points. Revit doesn't seem to allow you to group these common elements(within a design). I assume it has something to do with how the whole connector element works and not the actual Beams & Columns
Please add functionality to Group Steel Connections. Similar to the Master/Slave option in Advance Steel. Alternatively, allow Steel Connections to be added to a Revit Group. Always a mission if a connection changes to update similar ones.
With this, the ability to save your connection in a library for later re-use.
Users should be able to create custom connections starting from a template, then apply the custom connection to multiple (similar) analytical nodes at once . I used to do that a lot in Strucad a long time ago. On the analytical model (axis/wireframe model) i was simply selecting the desired nodes and apply a predefined or custom connection. In case of error/misfit Strucad just refused to apply the connection issuing a warning about the situation. The big problem was mirroring the connection. All the nuts and bolts were going backwards making things impossible. A workable alternative was rotating the connection by 180 degrees, but was unreliable, the slightest rotation mismatch would result in connection error.
Revit 2019 has new integrated structural connection functionalities, however the implementation of those raised the limitation, that it is not possible anymore to create an assembly or a model group of structural frame elements modified with steel features, such as cut, weld, bolt, connection...
More information documented about this limitation in the Revit Help:
I believe steel elements modified with connections are meant for fabrication purposes. Therefore the steel elements should be grouped in sub-assemblies (=main I,H profile+all stiffeners, gussets, plates, etc) and assemblies(=several sub-assemblies staged together). And only afterwards you should group similar assemblies or give them similar codenames. At such late stage of the design process (connection detailing) it makes little sense to group/select just frame elements without their stiffeners, baseplates, gusset plates, etc.
Yes, we need assemblies for steel elements. But due to structural connections nature it will have limitations - no moving, no copying, no type selection. Only views isolation and automatic instance comparing.
ipselute you propose hierarhical assemblies. I think it is more global separate idea.
@YarUnderoaker: Why bother copying individual elements, when you could copy entire (sub)assemblies much faster? It would be easier for the software, the computing time would decrease dramatically. Plus, assemblies should be created erection-wise. Assemblies should be as easy to transport and manipulate as possible. In many cases, assemblies are created by several specialized subcontractors. You absolutely need to control what assembly goes to what place, at what time, in what sequence. Mounting phases determines transportation and erection times. Every assembly must be time-scheduled in a gantt chart.
@ipselute I totally agree with you. I am not sure if this limitation is temporary or not. It makes perfect sense for including the connection details in an assembly. And I am surprised Revit 2019 limited this ability. Please update us to show road map for this feature. Learning Advanced Steel when we are so close to use assemblies doesn't make sense.
In the spirit of bi-directional communication with Advance Steel and creating the ability to have Revit sub-assemblies of steel connections and main-assemblies, please ensure that part marking from AS to Revit also transfers with each model update.
It is necessary for AEC design coordination that we can create framing assemblies and include steel connections to improve quality of interdiscipline model reviews.
@Geoffrey.Jennings I agree! A way to define sub-assemblies within a main-assemblies makes it manageable and follows workflows to divide complicated fabrication into smaller manageable pieces.
New forRevit 2020 is the propagate joint option, but also along with this is the ability to create a series of connection configurations, as a duplication and stored with a different reference. This allows the user to create and store different connection configurations/variations within the model.
This allows for the selection of the Group instance and then modifying the parameters within the Group via the new dialog interface available.
The procedure for applying a basic joint is the same as previous versions, but then the Modify joint options process changed, before the option was available to edit default, now this is changed so the option needs to be selected by the ‘override in instance’ option in properties dialog. With this in place, you can select this option and then modify that instance of the applied connection, but note if to remove the check box tick, the joint will revert to the default stored parameters.
Within the option now available via the Edit type under properties, this opens a new dialog interface that allow for the duplication of the joint and then with new instance name reference, the parameters are stored under the New reference. This reference can be seen in the Steel connections listing under the project browser.
With this in place it can then be used and propagated within the model, also then edited, as all the joints with the Same instance types will alter if the parameters are changed in the source parameter stored for the joint/instance. For example, if the base plate thickness changed for a type A reference, you would alter the joint type in one location and then via the ‘modify parameters’ all the connections of that reference/type/instance will change in the model.
How can this be useful?
So, where an engineer may have several different types of the same joint, these can be created and stored within file, then applied to the beams with similar conditions as required, but with it being a “type”, should that type have to change, then you can go in and edit the main parameters and they will all update. Similarly, if you wished to change a single connection or several to a different type, this can be done by selecting those connections and changing the sub type of stored connection parameters.
Revit 2020 - Steel Connections Group types (instances) and propagate options.
"in Revit 2020, trying to apply single sided endplate connection and also moment end plate, but once applied seem unable to edit the connection, the modified button is greyed out on ribbon. Previously in this test model I had propagated this type of joint and found I could not modified the joint details, so deleted them, but still the same when reapplying. in same model I have some base plate connections, that I propagated and I can't access the joint parameters."
So when I click the checkbox for example, it becomes instance and the modify parameters is available.
What is the purpose of that checkbox? for example instance would be like a temporary or to do a try and error while modeling the desired connection shape ? Cause if I want to calculate the amounts of connections, the easiest would be with the type properties that way you can repeat the same connection on the desired places. Instance is only for the selected one. for me by just modifying the type or duplicating it, you will have a better control for calculating the amounts of connections. Or is there a way to copy the same instance to several connections?
And this is also preventing bind the link to a new file! Are you kidding me that your new fancy development is blocking me to do something and I have to wish for a fix? Seriously?
Need to open the feature that can group connections (Plate, Blot, Anchors .....). The fact that in 1 project I work with steel structures with steel grades that are not specified in the standard that Revit supports, this saves me and the team a lot of time when changing the design plan.
I just went to try assemblies again after many years, to create a set of shop dwgs for a very small project... can't even see the holes in the assembly parts created by the steel connections. What a Joke!
It's September 2024, 6 years since the original post. Donald trump and Kamala Harris are battling it out for the US presidential elections. Thought I would give some context for the historians who find this message long after they are both out of office and structural ideas like this still are yet to be fixed.
can this feature be added soon? its frustrating having to copy the same support around that i cant group because i have plates/bolts from the steel tab
