Reality capture is a process of capturing as-is conditions as images or point clouds using various means, including laser scanners, LIDAR (light detection and ranging) sensors, 360º cameras, unmanned aerial vehicles (UAVs), and more. All of these different modes spit out different output files that can then be converted to usable point cloud or vector data. Extracting construction intelligence from the point cloud or vector data and sharing it in a consumable format is the key for the success of any reality capture process. This class will detail laser scanning and UAV data-capture and intelligence-extraction workflows for different use cases, such as quality control/quality assurance, construction planning, site logistics, data-rich 3D modeling, intelligent as-builting, construction progress reporting, and so on.

Our company, ACCIONA, has been committed since its 1862 founding to pushing forward innovation in order to develop nontraditional ways to solve problems, and to always looking for new business and new initiatives. That is the main reason why, 3 years ago, ACCIONA's Innovation Division started to work in 2 different technologies: reality capture, looking to transform the real world into a digital world; and large-scale 3D printing, aimed at creating new 3D-printed elements from CAD digital files. Both technologies were especially interesting for preserving our cultural heritage. In order to probe both worlds-physical and digital are interconnected due to both technologies-in ACCIONA, we decided to start a pilot project that let us capture an existing structure (like a sculpture or a part of a building) using reality capture technology, and then 3D print a replica using concrete large-scale 3D-printing technology.
In this session, we'll take a look at a workflow under the Autodesk umbrella to process photos collected with an unmanned aerial vehicle (UAV). We'll cover best practice workflows, from processing the drone data in ReCap software, taking those results into InfraWorks software for use and further processing, then finally moving them into AutoCAD Civil 3D software. The end result will be a functioning TIN surface inside AutoCAD Civil 3D, as well as a georeferenced orthomosaic.
Let's dive into the complete process of creating an .rcp file while in ReCap Pro software and importing the point cloud into InfraWorks software, and see the step-by-step process of creating both a usable InfraWorks surface but also extracting features from your point cloud using both the new point cloud terrain and point cloud modeling tools within InfraWorks. The point cloud modeling tool is like your description keys in AutoCAD Civil 3D software, but instead of 2D blocks you'll get 3D features like power poles and trees automatically inserted into your model. We'll take you step by step through the process to help save you time.
Last year, our team undertook the task of capturing and generating the existing condition of a building in downtown Toronto, Canada. This project was a commercial building that included a parkade, mechanical spaces, office areas, and retail space. It required over 1,100 scans, or 7 trillion points of data, to capture all spaces needed for redesign and as-built modeling. This Revit project required LOD 200 modeling process for architecture, structure, mechanical, electrical, and fire protection. Using Revit software, ReCap software, and Collaboration for Revit cloud service we were able to move from raw scan data to a Revit model efficiently. Other challenges were management of large data sets and collaboration between team members in different geographical locations. We'll show you how we planned and executed this project, and let you know what lessons we learned.
Designing and making a custom-fit Ironman suit with my son for Comic-Con International: San Diego is the inspiration for this class. It's like asking a tailor to use CAD for textile design or requesting a well-cut Italian suit made from metal. It started with the shape of my son. Then the compounded complexity of modeling sheet metal layers that custom fit him. Last but not least, how were we to work out the flat pattern of these complex surfaces? Finally, we had to make it, but with what and how? In this class, we'll explore a digital workflow with Fusion 360 software. We can use ReCap Pro software to convert human scan data to mesh model. We can refine mesh model with ReMake software. We can use Fusion 360 for sheet metal design based on the human mesh. And we can do flat pattern creation with ExactFlat Online software. We then lay out a nested flat pattern and cut on stock sheet using Fusion 360 CAM 2D profile cutting. We assemble all the parts together, and the custom-fit Ironman suit is finalized with perfect shape and size.
LIDAR (light detection and ranging) is being collected with amazing speed, accuracy, and precision. This class will examine opportunities to collect data using Leica static scanners, backpack scanners, and mobile mappers, and how to extract intelligence from these point clouds using InfraWorks software and ReCap software.
Using drones and unmanned aerial vehicles (UAVs) on job sites to capture the existing conditions has gained a lot of popularity, thanks to cheaper equipment and a growing demand for accurate and up-to-date frequent surveys. ReCap software offers a complete set of tools to process UAV photos and to create 2D, 2.5D, and 3D deliverables that will be used in the Autodesk portfolio to extract the right information for the user. In this hands-on class, you will learn a complete process using ReCap in combination with InfraWorks software, AutoCAD Civil 3D software, and Revit software to extract various meaningful data from UAV photos, such as measurements (distances, surfaces, volumes), digital terrain model (DTM), BIM model, movies, virtual reality content, and so on.
This class will discuss the benefits of capturing existing conditions using laser scanners on a very large retail project. We will discuss the integration of point cloud data within the intelligent model in Revit software. You will learn how to utilize laser scan data across various components within the Autodesk Architecture, Engineering, and Construction Collection (Revit software, Navisworks software, ReCap software). This class will also discuss data collection of building equipment using BIM 360 Field software to connect project stakeholders located across different offices.
This class will walk through an early construction case study of a boutique dual-branded hotel in midtown Atlanta that began in January 2017. Beginning with establishing existing conditions and site logistics, working through MEP (mechanical, electrical, and plumbing) coordination and structure build up, this class will cover a wide variety of construction technology integration. Fully designed in Revit software, this project team embraced using the BIM 360 platform-including BIM 360 Docs software, BIM 360 Glue software, BIM 360 Field software, and BIM 360 Team software-to manage documentation and project coordination between the design team, general contractor, and trade contractors. We'll also explore the benefits and challenges of reality capture and photogrammetry in an urban environment using laser scanning and unmanned aerial vehicle (UAV) flights in conjunction with the ReCap Pro software.
The class will focus on multiple use cases provided by an intelligent model. A validated and functioning model is important for multiple areas of real estate, but it becomes vital to be able to trust data when working with complex critical infrastructure. It is essential to understand the limits of software and use them as stepping stones to creative solutions. We will cover many of these creative solutions, showing multiple areas in which we can use validated models to improve operations. It is also beneficial to use Dynamo software for solving challenging problems that can not be resolved by modeling software.
InfraWorks software facilitates engineers, planners, and architects in the making of complex decisions. Of equal importance is the role it can play in explaining the complexities of the decision-making process to a less technical audience, making the "why," "how," and "what" accessible and engaging. As part of a new plan for its central core, the City of Vancouver is replacing a viaduct system, the only remnant of a proposed freeway, with a more resilient and connected street network. Public engagement is a key component of the process-and with extensive changes being proposed to the street system and the public realm, the challenge has been to present the future state and how things are being phased/changed in a clear, accurate, and interesting manner. This class will show how an interdepartmental team is collaborating to use the full palette of InfraWorks software's capabilities-including web maps, ground-based LIDAR (light detection and ranging), and virtual reality-to make the public an informed and engaged partner in the process.
Miami Marine Stadium was the first U.S. stadium constructed specifically for power-boat racing, and its use isn't the only thing unique about this structure. Its design consists of a dramatic, cantilevered, folded plate roof supported by 8 sloped, tapered columns. The facility has been condemned since 1992, but it's finally set to undergo a major rehabilitation. This class will share techniques used by Langan and VIATechnik to laser scan and model the entire structure. Matt Sipple from Langan will discuss his approach to capturing existing conditions with an unmanned aerial vehicle (UAV) and a terrestrial scanner, and Kyle Hudson from VIATechnik will share tips and workflows for modeling this complex geometry in Revit software. Reality capture and modeling strategies used on this project are applicable to all facilities with complex geometry or one-of-a-kind shapes and forms.
