AutoCAD has supported 3D parametric constraints since AutoCAD 2010, but except for 3D power users, most AutoCAD drafters don’t take advantage of this dynamic modeling environment and the accuracy and information it can bring to your drawings. Here are eight AutoCAD tips for parametric modeling.
Tip 1. Cadalyst and Autodesk blogger Lynn Allen explains the basics of parametric constraint tools and how to use geometric constraints such as parallel and perpendicular lines in AutoCAD. You also learn about the common parametric battle of “who changes whom.”
Tip 2. AutoCAD expert David Cohn takes the constraint talk a little further using tangents, perpendicular lines, parallel lines, concentric circles and arcs, and horizontal constraints on the same objects. He also explains the Autoconstrain tool to assign a number of constraints in one pass. As each constraint is applied, AutoCAD shows an icon in a constraint bar adjacent to the object that gets highlighted when you hover over it. Dimensional constraints and setting up formulas for them are discussed as well.
Tip 3. Lynn Allen takes dimensional constraints even further in the Dimensions tab and shows how using dimensions can make your drawing life a lot easier. Using dimensions can change the length of a line, change relationships between lines, and create new dimensional relationships.
Tip 4. Now that we’re experts on dimensional constraints, AutoCADExchange is going to introduce us to the world of inferred constraints. No longer will you be drawing first and implying constraints second. Inferred constraints work with you as you draw and apply themselves while making sure your drawing is set up properly.
Tip 5. AutoCADExchange explains another way to modify the values of geometric constraint, other than double-clicking on the value itself, using the Parameters Manager in the Parametric ribbon. This gives you a visual of all the parameters and allows you to edit them not in the drawing itself, but in the Parameters Manager. The geometry in the drawing is adjusted accordingly based on changes made in the manager.
Tip 6. If you receive a drawing that has conventional dimensions, you can still convert them to parametric constraints. AutoCADExchange explains how using the Convert command in the Dimensional Tools ribbon allows you to change any line, arc, or circle into a dimensionally constrained one. You can access these new parameters from the Parameters menu.
Tip 7. All of the dimensions we’ve discussed so far have been “dynamic” dimension constraints, meaning that we’re mainly concerned with how our drawing functions, what its parametric relationships are, and how they work. We haven’t really considered annotational dimensions that will show up on a drawing, what its cosmetic look is, and whether a construction document be made from the drawing. In the Properties tab, switch your drawing to Annotational, and you’ll immediately notice a different look. See more from AutoCADExchange.
Tip 8. Now that you can create dimensional constraints, you can use them to speed up your AutoCAD drafting by using dynamic blocks, which are the same as regular AutoCAD blocks but have parameters and actions added to them. These can be reused for common drawing elements such as doors, walls, and plumbing fixtures. Dynamic blocks are great to use in AutoCAD if you’re also a Revit user because Revit’s tools are entirely parametric and based on dynamic blocks. Using 3D in AutoCAD effectively prepares a drafter to exist in the entirely 3D world of Revit, and some dynamic blocks can even work in both programs. Learn more about dynamic blocks from AutoCAD guru Thomas Russell.

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. Just because you are use an integrated workplace management system (IWMS) or have relevant GIS data doesn’t mean it provides a single source of truth.

Prior to 3D printing’s arrival on the manufacturing scene, the US military supply chain was often met with lengthy and arduous timelines for critical asset production. This not only stalled the manufacture and repair of essential equipment within the military supply chain, but it also impeded military readiness, and with high price tags to boot.

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:
