InfraWorks Overview for Beginners

When I talk about “BIM”, most people immediately think of Buildings (the “B” in ‘BIM’). But BIM is so much more than just buildings. It also includes the surrounding site and infrastructure that help support a building. And for that, there’s Autodesk AutoCAD Civil 3D which is a great tool for creating a highly detailed design of the site grading, roadways, drainage and utility systems. But what about the early stages of a project when you’re dealing more with conceptual designs? That’s where Autodesk InfraWorks 360 has a leg up on AutoCAD Civil 3D. InfraWorks 360’s intuitive and sleek interface allows you to focus on what really matters – the design.

Rapid Model Creation Using Model Builder

InfraWorks 360’s Model Builder tool allows you to create a 3-dimensional site model with nothing more than an address. After entering an address and giving the model a name, InfraWorks 360 will pull together any data it can find for roadways, water areas and buildings using OpenStreetMaps data; terrain imagery is gathered from BING Maps and the digital terrain model data is from one of the following sources: USGS 10 and 30 meter data, SRTMGL1 30m data or ASTER GDEM v2 30m, depending on where in the world you’ve selected. Once the model is ready for download into InfraWorks 360, an email will be automatically sent to the Autodesk account that was logged into InfraWorks 360 at the time the model was created.

Multiple Data Sources

InfraWorks 360’s abiltiy to read over 40 different file types makes it an ideal tool for creating a schematic design. An architectural Revit model can be imported and located on the site for sight analysis, sun/shadow analysis, parking lot and roadway design, all in context with existing surrounding buildings and site features. And the type of data that InfraWorks 360 can read isn’t just limited to 3D dimensional models. GIS data such as SHP, SDF and Geodatabase files can be read and then linked to models to represent site features like manholes, underground piping, sight lighting, vegetation, and even existing building footprints. Even AutoCAD Civil 3D data such as pipe networks, surfaces and alignments can be imported to quickly create a model based on a rough layout from Civil 3D. Or simply sketch the roadways within InfraWorks 360 and then import them into Civil 3D for a more detailed design and analysis based on survey grade information.

Roadway Design

InfraWorks 360 gives you three different roadway design tools for quickly creating conceptual ideas, each one with slightly more features than the previous. The first roadway design tool is the most basic of the three. And as its name implies, Sketch Roads allows you to sketch in roadways and apply design speeds to horizontal curves. The second roadway design tool are Design Roads. Design Roads have the same basic funtionality as Sketch Roads but also includes a profile editor to modify vertical curves. They will also clean up nicely with other Design Roads wherever they intersect, creating Intersections or Roundabouts which can then be further refined based on number of turning lanes, design speeds, or the Roundabout’s tilted plane bearing and/or slope. The third roadway design tool is Component Roads. Component Roads includes all of the features of Design Roads but includes super-elevation modification tools and the ability to attach additional roadway components to the road such as sidewalks, curbing, bus stop lanes, and much more.

Design Analysis

With InfraWorks 360's design analysis tools, you can analyze the model in multiple ways such as applying a terrain theme to color-code different elevation bands to get a sense of where the high/low spots are, sun/shadow analysis based on not just the geographic location of the model, but also the date and time of day, watershed analysis, reporting of terrain statistics to quickly see rough cut/fill volumes based on design roads, coverage areas, water areas, etc., flood simulation, traffic analysis, create suitability maps to determine the least & most costly areas to excavate based on utilities/buildings/roads and so much more.

Presenting Your Design

InfraWorks 360’s ease-of-use doesn’t just stop with laying out roadways and adding context to the existing model. Its ability to quickly create a presentation from either a static image using the Snapshot tool, the Storyboard Editor to create flyover animations or even go mobile by creating scenarios with the Scenario Browser and viewing them on the iOS app (https://itunes.apple.com/us/app/autodesk-infraworks-360/id557267648?mt=8).

Virtual Reality

And with virtual reality being the next big thing in the AEC industry, why not create a VR experience you can share? Unfortunately, this is one feature that is currently missing in InfraWorks. However, it CAN still be done but you’ll need to export the design model in InfraWorks 360 to an FBX file which can then be read by Navisworks. From there, you simply set your point of view and render the current 3D image to a stereo panorama and let Autodesk’s cloud rendering service do the rest. Sharing your VR experience is as simple as sharing a web link or the unique QR code.

Conclusion

InfraWorks 360 is a fantastic program for generating multiple schematic design options within the context of the existing surrounding environment in a short period of time. Whether you need to design a road based on a certain design speeds criteria perform some quick sun/shade analysis for a building on a potential site, or simply need to create a quick image for a meeting or presentation, InfraWorks 360 is all about giving you the right tool for the job to present your design ideas. But don’t take my word for it. Download the free 30-day trial and try it out for yourself.
