Revit 2022 – What’s New: Platform and Structural tools

After the most unusual year that many of us have experienced, the new release of Autodesk Revit 2022 will hopefully be the dawn of a brighter year. In this review we will take a look at the new structural features and improvements and also talk about the all-important platform tools that underpin the Revit 2022 platform.

This year follows a similar theme to Revit 2021 with a focus on improving the steel modelling workflows and continuing to build on the reinforcement tools. However, there is a really strong set of platform tools this year which I genuinely think that many will find useful and use on a day-to-day basis. This is significant and highlights that Autodesk are starting to improve the core tools which, of course, will benefit many industry sectors. Let us start by looking at some of these core improvements.

New Platform Features

You can now create tapered walls which are useful when working with retaining structures. You can set both an interior and exterior angle for the wall which will remain consistent when walls have different heights and levels. In the example below, a retaining wall has been modelled and reinforced for a carpark.

A few years back, Autodesk added 3D levels that could be seen and edited in the 3D model. This was a very welcome addition but what we really needed was 3D grids. They have now arrived with Revit 2022! They have a very similar look and feel as the levels and can be edited in the 3D view. This is great when you need to extend grids in the vertical plane, previously you would need to do this in a section or elevation. This is even more useful when you need to extend curved or skewed grids.

A great new feature is the native support for exporting PDFs and naming the sheets based on a concatenated set of parameters. Think about the below problem with sheet naming (ISO19650) and the Revit view references such as section and elevation markers.

We can now export the sheets as PDFs and automate the naming based on naming rules. In the image below you can see that I have used a series of shared parameters from the view and project to form my sheet naming convention! A Very welcome feature.

On a similar theme, revisions can often cause pain when you need to combine a revision state with a number. For example, some drawings may be at preliminary stages and others at the contractual stage. We now have the ability to create several numbering strategies and use these for various revisions.

You can then assign the relevant numbering sequence to each revision as required. In the example below you can see the revision table showing both preliminary and contractual revisions and the current revision displayed in the bottom right of the title block.

Phasing can now be added to a filter in visibility/graphic overrides. This is a big deal when you need to create specific views, hide particular elements created in previous phases or simply display elements in different colours based on phasing. A great feature for contractors!

When creating schedules, you can use filters to reduce the number of parameters that you have to scroll through, this is very significant and streamlines the process of creating schedules as more and more shared parameters are added to families.

Talking about schedules, we can now split these across sheets. Previously, if I wanted to create a rebar bending schedule for each sheet, I would need to use shared parameters and a series of filters to create ‘separate schedules’ for each sheet. I can now simply split the schedules and place them on the relevant sheets.

Once the schedules are split, you will see the following ‘child’ schedules in the project browser, you can simply drag the relevant ‘child’ schedule onto the sheet. The schedule length can be controlled for each child.

There is now support for multiple tags and leaders, this new tool allows a number of elements to be tagged with multiple leaders and it is also possible to recover the quantity!


Simply add new hosts to the tag and multiple leaders are added and a count is produced. Note that the instance properties of the tag will display the host count.

Steel Connections

Each year Autodesk continue to build on the steel connection functionality allowing designers to model connections based on standard macros or create custom connections. In Revit 2022 you can now create ranges of applicability which will lead to the use of standardised connections. For example, a base plate with the dimensions of 450 x 450 x 25 could be applicable for use on a UC column, a SHS column or certain CHS sections. The connection can also be selected based on member end forces and materials.

This new functionality will be useful when adding simple connections (pinned connections) that are selected from the green book. Currently, the connections can be applied to the model with the use of Dynamo or Dynamo Player which adds the connections based on a library of connections.

Another improvement has been made to the structural connections category that allows the user to set default materials for plates and profiles in the Object Styles dialog. This is much quicker that individually changing each element.

There is still a lot of the connection functionality that is hard coded and libraries that are dependent on the Autodesk Advance Steel databases. Also, we will need the ability to produce fabrication documentation and NC code from the model. These issues will need to be addressed to detail a steel model and get fabricators interested in Revit as a detailing tool. I am sure these tools and functions will be addressed in future releases.

Reinforced Concrete

The reinforced concrete detailing tools continue to be developed this year allowing some great new workflows and modelling capabilities. In this release we can now model reinforcement bar by picking two points and we can also move rebar in a set.

Let us first look at the modification of rebars within a rebar set. Individual rebars within a rebar set can now be modified by moving, rotating, or deleting the bars. This is very useful when the links or bars are clashing with other elements. In the example below we have a drainage pipe cast into a ground beam. We can now simply move rebars, so they do not clash. This is very useful for highly congested areas where steel fixers need to understand exactly where to place individual bars.

You simply select a rebar set and you will then see the ribbon displayed below. Here, you can edit bars, remove bar or reset the rebar to its default state.

Rebar can now be placed by two points. This is very useful when you want to place links in pairs as shown in the image below. The standard method used is to expand to the cover which is useful for certain bars but not for the links in the middle of the beam!

The new method simply allows you to pick two points and the shape is created.

A variety of new tool tips are also displayed directly at your cursor which is very useful when first learning Revit. For more experienced users, these tooltips can now be switched off.

You can also see that the vertical and horizontal placement options have also had an overhaul.

Conclusion

In summary, the Revit 2022 release has been great for the new platform tools that most of us will end up using on a daily basis. Features such as the 3D grids, tagging, revisions and PDF exports are very welcome, and it is great to see Autodesk focusing on these core tools. As said before, these are tools that are used daily by all users.

The reinforcement tools continue to get more and more useful and now make it simple to add rebar to simple and complex concrete forms. Also, we can now produce detailed 3D views showing exactly how our bars should be fixed.

Revit Sheets, ISO19650 and Naviate

When working with Revit and ISO19650 the naming requirements (information containers) are a concatenation of multiple fields such as the project reference, originator, level, zone etc. The temptation for many is to simply type this very long string into the Revit Sheet Number. However, as many of you have probably realised, the consequences of this approach are not desirable!  An obvious issue is the referencing of the drawing number on sections, elevations, and callouts!

The answer is to create shared parameters that build up the required information containers. These can be used to form the drawing number and used to organise the sheet views in Revit, very useful for large projects. Some of the shared parameters will be added to project information (global for the project) and others for the sheets (each sheet can have a different value).

The sections, elevations and callouts can then simply reference the Sheet Number, or for multi-disciplinary design can also include the ‘Role field’ to provide a unique number. For example, ‘S-1040’ or ‘A-1040’.

This all looks very promising until you need to issue PDFs and DWGs with the correct ISO19650 naming convention. If you batch plot or export AutoCAD DWGs from Revit, you will have a file name such as:

Project Name – Sheet – 1010 – GROUND FLOOR GA

Clearly, this does not meet the ISO19650 naming conventions and your documents will be rejected by the CDE (Common Data Environment).

A very useful solution is to use the Publish tool from the Naviate tools. This is located on the Naviate ribbon in the documentation panel as shown below.

Once the Publish tool has been launched you will be presented with the following dialog. Here you can configure and save your various deliverables. These can be formats such as PDF’s, DWG’s and IFC’s.

You can set up the configuration of each format to generate the files that are automatically named to conform to your naming convention, in this case, ISO19650. You can reference shared parameters from the sheets or project to concatenate the file name.

Once the settings are configured and saved this becomes a single-click operation to create all the outputs required for the weekly delivery of documents and information saving countless hours, manual renaming and potential typos of document names!

Feel free to download our trial and test out the workflow for yourselves. You can download the appropriate version of Naviate for your industry here!

Accelerate your Revit RC Detailing with the Naviate Rebar Extension

I am sure some of you are currently using Revit to produce 3D RC models and details. Those of you that are, will be gaining the benefits of working in a fully coordinated model with automated bar schedules to BS8666 and intelligent tagging. Those that are not using Revit should seriously consider making the transition! Having 3D models and presentations that show how the various layers of bar should be fixed gives you confidence in your design, especially with complex shapes and prefabricated cages. It is far less ambiguous to present 3D images and models to fully understand the design intent.

Anyway, I wanted to showcase some free tools from Symetri that you could be using right now on projects to streamline the creation of typical reinforcement. The below image shows the Naviate REX ribbon.

The first part of the ribbon focuses on the actual macros to generate the reinforcement. This is like the original REX tools that Autodesk provided a few years ago. However, the big difference is that the Naviate REX tools allow the shape codes to be generated from the shapes loaded into your template. This is a huge improvement as previously your model would have generated shapes like ‘stirrup shape 1’, Stirrup Shape 2’… etc.

The second part of the ribbon has some very nice productivity tools associated with the display of rebar.  To show or hide rebar, both in the 3D and 2D views required the use of view visibility states. This is quite time consuming and laborious in Revit as you had to do this for each view. These tools alone will save you a lot of time!

Let us now look at some of the macros that provide automated modelling of typical reinforcement. I will start with the pile caps and piles.

A time-consuming pile cap configuration to reinforce manually is the triangular one shown below. This has varying reinforcement and can have five layers of rebar to deal with.

As you can see from the dialog, there are various reinforcement types to select and options to generate other arrangements. You could just generate the bottom layers of bar or add top layers as well if required.

The reinforcement is generated using standard Revit rebar sets which enables easy modification to add additional reinforcement to the model. In the image below, you can see a combination of piles, pile cap and circular concrete columns. Additional starter bars have been added and the pile reinforcement has been adjusted. This is all possible with standard Revit tools.

Moving on to strip footings and walls, again we can place out most of the bar using the macros and then finish off items such as starter bars. Again, this is much quicker than defining the bars from scratch and creating rebar sets.

I have noticed that some of the shape codes do not generate as expected but you can just swap these out for the correct UK shapes. Another big benefit is the ability to save configurations for typical elements. For example, the slab opening macro can be configured and saved as an RXD file that you can recall and use elsewhere in the project or perhaps on a completely new project.

Some of you may already know that you cannot use the built-in interference check in Revit on reinforcement. Reinforcement bars are special objects that are optimised for performance and will not show in an interference check. However, the Naviate REX tool can check a reinforcement layout before you send this to your client! Of course, you can also use Navisworks for comprehensive clash detection and resolution but this is a convenient tool within the Revit platform.

We all know that some interferences that are found by the software may not be real problems out on site. The steel fixer will simply shift or deflect the bar. In these situations, you can set an effective diameter to account for the actual diameter of bar as well as a tolerance that you want to set. Also, you could just select reinforcement with a diameter greater than 16 and only check for clashes between these bars.

So, I would urge you all to download this free set of tools and take a look If you are currently producing RC models and details in Revit or are moving away from 2D detailing then these tools will certainly help you!
