Build Better Infrastructure – The New Features in Civil 3D 2021
Another release of Civil 3D just became available, just as you probably finished installing the latest 2020 “fix.” That was somewhat sarcastic, but I do some see much needed improvements to Autodesk Civil 3D 2021 and all other 2021 products. But we can’t just look at what’s new in our hero product, but all other complimentary products as well, so I will briefly mention a few of those.
Civil 3D Version Interoperability
Typically, the first question asked is about prior version interoperability. The AutoCAD format for 2021 is also the 2018 format they previously introduced. Meaning you should have no problem going back and forth between 2018, 2019 and 2020. The only exceptions to Civil 3D objects would be the newer Civil 3D object/features will not go backwards, but this shouldn’t be a problem.
New and Enhanced Pressure Network
One of the bigger changes in Civil 3D 2021 is the introduction of path-based pressure networks, and multiple enhancements to the overall pressure network workflows. For those that do a lot of subdivision work, or complex pressure systems, you will really like these changes!
- Pipe Runs – This is a fantastic change to how pressure networks are created and modified. I wish they would do this for gravity networks now. Your pressure network can still remain as one entire network, but you can have separate “runs” within the network. This is great for subdivision development and will make your network much easier to manage.
- Paths – Fitting can be added and updated automatically when grip edited or moved. For example, if you have a 45-degree bend, and you grip edit on portion of a pipe, that bend can now change to the proper angled bend. This is a very cool addition.
-
Fig_1-768x307.png - Pipe Run Profile Settings – If/when you base your network on a cover depth, the pressure network can now remain dynamic to a profile.
- Profile – Better functionality for pressure networks have been introduced, such as adding vertical deflections just as you would a PVI in a profile.

AutoCAD Platform Items
Here are few new things to look forward to in all AutCAD platform products:
- XREF Compare – Similar to the drawing compare feature, you can now compare the changes made to a drawing file attached as an external reference (xref) in the current drawing. Any changes to the referenced drawing or a compared drawing are highlighted using revision clouds. (You can also uncheck this option prior to reloading your XREF, or change the variable to disable it.)
-
Fig_3.png - Drawing History Support (Subscription Benefit) – If you save drawing files to a OneDrive, Dropbox, or Box account, additional versions of these drawing files are created as you work, creating a version history. The previous versions will be listed in the new Drawing History palette so you can compare them with the current version of your drawing.
- Trim and Extend – I must admit, I actually strongly dislike this change. Instead of having you select objects or boundaries for the TRIM or EXTEND command, the new “quick” mode selects all potential options by default.
- To revert back to the standard way or using the Trim/Extend command, type in one of the commands and from the command line choose MODE, then switch to Standard.
- Misc Commands
- BREAKPOINT – Allows you to break an object at a specified point
- XCOMPARE – Compares an attached xref with the latest state of the referenced drawing file, highlighting the differences with color within revision clouds.
- REVCLOUD – Some nice enhancements to the REVCLOUD command which allows you to control chord length or modify a cloud.
- XCOMPAREENABLE – Enables the comparison between an xref and the referenced drawing file.
- TOUCHSCREEN ENHANCEMENTS – I’m not sure if this has been around a while, or I finally got a laptop cool enough to have touch screen capabilities, but there are a couple enhancements to the Pan and Zoom and selection.
Infraworks Integration
- Add Bridges to Corridor – The workflow between Infraworks and Civil 3D has been enhanced to add bridges into your corridor design. If these bridges are modified in Infraworks, you can simply reload them in Civil 3D.
- Interoperability between Civil 3D and InfraWorks for Corridors – This enhancement has been needed for a while now! You can now create corridor component roads in InfraWorks from Civil 3D corridors. A corridor component road represents the designed corridor in Civil 3D and is read-only in InfraWorks.
When you bring a Civil 3D corridor into InfraWorks as a corridor component road, geometry for the shapes and links is created in the InfraWorks model.
-
Fig_4-768x544.png
Most, if not all, of the 2020 update enhancements have been rolled into the software. Some of the following items below may be of interest and really help in streamlining workflows and enhancing design.
- Use enhancements to gravity network analysis including the support for multiple catchments per structure.
- Use the new drainage structure parameter mapping feature to map the parameters of Part Builder parts to parameters that are required for the Analyze Gravity Network command.
- Enhanced reference template features to manage styles and settings.
- The Manage Data Shortcuts command has been updated so you can specify a different data shortcut project path when the current path is still valid.
- Bring ArcGIS data into your Civil 3D drawings and save back, publish, and export data for use in ArcGIS.
- Export feature lines to LandXML files. This is a big benefit for survey and machine-controlled models.
- AASHTO 2018 design standards are included.
DYNAMO
DYNAMO for Civil was introduced in the 2020 release of Civil 3D and exploded with popularity! The Dynamo Player has now been incorporated directly into Civil 3D, so no need for a separate install, and has enhanced capabilities for use within the civil space.

BIM 360 Document Management (BIM Docs) & Collaboration for Civil 3D
Now I know this is supposed to be an AutoCAD / Civil 3D article, but I really think you need to at least take a look at BIM 360 Docs and the new version of Collaboration for Civil 3D and what it can offer to you and your design workflow.
Three key features that I see are file locking, file compare and versioning and the utilization of data shortcuts.
Bryson Anderson wrote a great article in the February 2020 AUGIWorld Magazine and explores BIM 360 Collaboration for Civil 3D in great detail.
I may not have covered all the features and there may not seem like a ton of new features, but the new features and enhanced features will help in your everyday workflows.
I would love to hear from you regarding the new features and features you would like to see added or enhanced, so feel free to call or email me anytime.

Transition periods are never easy. As businesses move from routine practices to uncertain situations, there’s a level of trepidation involved. Thankfully, there are ways to ease this anxiety—namely, by shedding light on the gap in old vs. new practices. At a time when many organizations are either in the middle of transition or running up against it, investment in visibility is imperative.
Nowhere is visibility more important than facility planning. Facility managers need oversight as they begin to adapt assets and workflows in the near-term and for the future.

The COVID-19 pandemic has been disruptive to physical workplaces for so many reasons. One of the biggest challenges for businesses has been adapting offices to new and often equally disruptive safety standards – social distancing, sanitization, contact tracing, etc. While there’s keen emphasis on these practices, indoor air quality (IAQ) in many offices is only now getting the attention it deserves.

Healthcare facility management is complex, especially since many organizations are open around the clock. Ensuring yours is at its best is expensive. Maintaining a building properly accounts for more than 80 percent of the total cost of operations and occupancy. Safety regulations constantly change. Patients arrive and depart on a variety of timelines. Healthcare workers regularly use spaces like break rooms and storage areas.

Does your business have a single source of truth when it comes to data sharing across facilities? Ensuring data is accurate, relevant, and structured is something any business can recognize as important, yet it is more difficult to achieve than most realize.

Americans spend about 90% of their time indoors, according to EPA reports. Whether it is their home, workplace, or another location, people depend heavily on a controlled environment. Everything from the air we breathe to the light we bask in is artificial or at least managed. In shared spaces, it is the responsibility of building owners and managers to provide healthy and safe workplaces.

Out of sight, out of mind. It’s all too easy to forget about asset maintenance when the assets themselves aren’t right in front of you. During the COVID-19 pandemic, this became more evident as employees went home and logged into a virtual workplace instead of coming to a physical space.

There are two distinct factions when it comes to working from home: those who relish it and those who despise it. Before COVID-19, working from home was a perk. When the pandemic hit, work-from-home (WFH) became a necessity to combat the virus’s spread. One person’s dream; the other’s nightmare.
As COVID-19 rolls on, employers are dealing with two sides of a war between those who want to return to the office and those who’d prefer working from home. Depending on who you ask, results are mixed:

The modern workplace is a far cry from spaces of the past. Banks of private offices gave way to an open concept fad that’s morphed into a hybrid of spaces, including personal desks surrounded by pony walls, hot and hotel desks, and collaboration areas.
COVID-19 threw workplace and space management into turmoil, but the return-to-work movement is underway. As employees come back to offices, stores, factories, and other businesses, the need for privacy in the workplace again takes center stage.

Mixed-use spaces – used by public sector agencies for different purposes – or even mixed-use cities present unique challenges for workplace managers under the cloud of COVID. Unlike single-use facilities, mixed-use spaces may see much larger groups of people come and go. Monitoring the health of every individual is likely impossible without strict contact tracing standards.

Historic buildings hold a special place in the hearts of architects, workplace planners, and employees. There’s something alluring about creating workspaces within the confines of century-old stone or retrofitting a Victorian Era home into offices.
For all their uniqueness, repurposing historic buildings for modern workplaces isn’t as easy as replacing a few light fixtures and brushing on a new coat of paint. Most older structures are governed by sometimes-strict regulations overseen by historic districts – the first was created in South Carolina in 1931.

The benefits of the Internet of Things (IoT) are undeniable. IoT-enabled technologies collect data that impacts cost, productivity, compliance, and security. However, that data is only as good as the analyses derived from it, especially when it’s connected to how workplaces are populated, and space is managed today and in the future.

Managing real estate for a single workplace is, in certain ways, simple. There is a single set of data for land, buildings, and leases. For companies with multiple properties or a global presence, the task becomes daunting.
A centralized data repository is the key to maintaining accurate and easily accessible information to manage real estate portfolios. But not all data systems are alike. Real estate planners and facility managers should consider several items when choosing a real estate portfolio management system:

Digital design data is a big data business. It requires secure management and storage, versions need to be stringently controlled, and teams need to access files readily so they can share that data with stakeholders.
For too long, however, designers, engineers, and CAD managers have relied on traditional document management systems, like network drives, to achieve this. While they do a great job with office documents, those same solutions don’t work well with today’s design files and models, for several reasons:

If your job involves capturing existing field conditions as part of the design and construction process, you’ll know it’s a tedious, manual, often analog and inaccurate process, which often leads to costly re-work.
Whether you’re renovating a building or involved in a large-scale infrastructure project, the process goes something like this:

As any surveyor or field engineer knows, capturing existing field conditions for an infrastructure project or building renovation is a tedious, manual, often analog, and inaccurate process – not to mention dangerous.
Renovations projects are a particular challenge since the infrastructure or building may be decades old and designed before the age of digital blueprints. You’re almost guaranteed to start a project using static 2D image documentation of existing conditions. Verifying and updating these manually is a lot of leg work.

Building information modeling (BIM) is poised for greater adoption by federal, state, and local government agencies. In Wisconsin, for example, publicly-funded projects over $5 million are required to incorporate BIM and 3D software from initial planning concepts to bidding documents and project closeout. Many DoTs, including MassDOT, FDOT, and CALTRANS are also embracing BIM for infrastructure projects.

It’s hard to imagine a world without digital. But as you look around you, much of the physical world was designed and constructed using traditional 2D blueprints and is yet to be captured in a digital format. This creates a challenge for AEC professionals to incorporate these as-built designs into re-build or renovation projects.
Traditional imaging techniques like photogrammetry aided in this process by allowing engineers to piece together photographs of as-built conditions and weave in GPS coordinates to create interactive 3D models, see below:
