The reality capture group at Autodesk is working on ways to acquire, manipulate, or analyze real scene data using laser scans or photos through ReCap™ products. While several AU classes demonstrate ReCap use and workflows associated with these products, this class focuses on how to programmatically access the reality capture web API to create or extend an application. We start with a quick overview of basic photogrammetry concepts and image parameters. Then we approach the reality capture REST API and discuss how to define a photo scene from multiple photos and create a dense 3D mesh. We cover some of the advanced features that are available to customize and refine the process. Finally we conclude the class with a complete example written in PHP.

3D technology has historically been reserved for large, exclusive, purpose-specific platforms. Users have been required to have advanced knowledge of laser scanning to operate high-tech scanners. As technology continues to evolve, laser scanning is just one piece that is moving to a smaller, inclusive, all-encompassing platform.<br/> <br/> In this presentation, Hexagon Geosystems CTO Burkhard Boeckem will take you through the journey of how this evolution led to the creation of the Leica BLK360, the world’s smallest and lightest imaging 3D laser scanner. Moving from the belief that AEC professionals couldn’t access the technology due to the high barriers of entry to democratising laser scanning for anyone with inspiration and desire to embrace new possibilities, the development of the BLK360 is opening opportunities previously thought unobtainable. Don’t miss this future-looking presentation and your chance to experience the latest in laser scanning technology.
This class will present the first SNCF rail project that implemented a BIM approach. The project consists of transforming the existing Saint-Cloud Station in order to interconnect to the future metro station and fit the increase of passenger traveler flow. As part of this presentation, we'll address the following topics: BIM for rail issues and expectations; SNCF challenges and expected BIM outcomes; overview of the Saint-Cloud project; reasons for using BIM on this project and expected outcomes; approach taken in partnership with Autodesk Consulting; outlook.
This class will be delivered by Kier Construction, a UK-based, industry-leading construction company, supported by Topcon and Autodesk. Kier will describe how they have applied Autodesk BIM 360 tools in collaboration with 3D laser scanners and total stations into their workflows on a complex construction project undertaken in the UK. Kier will demonstrate the key benefits of collaborative working, effective supply chain engagement, and adoption of technology on construction sites to realise and exceed client expectations. Using office-based software such as Navisworks, Revit, and ReCap, we will cover how using a variety of mass data capture techniques to gather as-built documentation combined with integrated on-site verification and management has improved efficiencies and reduced errors on construction sites. Kier will appraise the impact of using innovative new workflows to overcome interoperability challenges between several types of BIM authoring software.
This class will explore the implementation of an efficient workflow for 3D scanning of large plants. From laser scanning at the field until a point cloud, which can be combined with a 2D layout and 3D models, our scan projects count regularly more than 100 scans. After the scans are taken, the scans are removed from noise and then divided in layers according to the flow sheet. The buildings are also on a separate layer and divided into roof, walls, and floor. These scans are then combined in Navisworks software with a 3D model of a new line generated at our company. The 3D models are made with Inventor software. A 2D layout, which we receive from the customer, is also attached. This workflow has been improved on a lot since the start, and this is what we want to teach in this class. Recently we purchased a drone to capture photos at places that are not reachable for our scanner (for example, ducting on a roof). A 3D point cloud can then be derived from those photos and combined with the laser scan point cloud This session features ReCap, Inventor Professional, and Navisworks Manage.
The idea of using Building Information Modeling (BIM) models in facilities management has been raised for many years. One major reason why it isn’t widely adopted in the market is the mismatch between as-built model and built structure. Using reality capture technology, we can collect the scan data of the built structure and use it for as-built model verification. A list of discrepancies between scan data and the as-built model would be produced, and team members could validate the results and amend the as-built model when appropriate. This class will identify the workflow when using Revit software to verify the as-built model with the scan data, as well as the possible follow-up actions. We will use a third-party Revit plug-in for scan data identification with model category, and we’ll perform model checking using point clouds. We’ll explore a sample case to demonstrate the suggested workflow. This session features Revit and ReCap. AIA Approved
This class will explain the fundamentals of laser scanning, explore its value and application in building construction, and reveal how reality-capture tools are shaping the future of the industry. Attendees will gain a basic understanding of what data is collected and how, typical scan-data processing workflows in ReCap software, and analysis for ASTM E1155 Concrete Floor Flatness & Levelness (FF/FL) reporting. We will share best practices for capturing data in the field; accurate and precise scan registration to ensure reliable results; and several examples of actual projects where ReCap software was used to enhance processes and communication. This session features ReCap.
Should you consider adding this tool to your workflow? While there are some very powerful laser scanners that are accurate and fast for larger spaces, and photogrammetry that is cost-effective but not as accurate, there is a growing number of more-affordable handheld scanners that can be capitalized on to augment the as-built conditions, and in some cases they are more effective the other alternatives. We will discuss the current and forthcoming technology that may augment current scanning methods. This class will address the following questions: What is a reasonable expectation from a handheld scanner and return on investment? What is the workflow for maximizing the scanner’s use for as-built and quality assurance / quality control uses? How can we best capitalize on scanning at this scale? When is the right time to consider handheld versus other scanning technology? Where can this scanning method be most effective? This session features ReCap and Navisworks Manage.
Reality capture techniques are becoming commonplace in many aspects of design. The factory layout process is no different. From the clean up and orientation of the point cloud to the possibility of using point clouds as factory assets, when it comes to utilizing point clouds with Factory Design Suite software, there is a lot to consider. Join us in this class as we focus on the various techniques and workflows for capitalizing on point clouds captures in the factory layout process. This session features Factory Design Utilities, Inventor Professional, and ReCap.
What if we—Autodesk, Inc.—would use our own technologies for our own needs? In this class we will show you how we applied interesting workflows involving the following software: ReCap software, Revit software, BIM 360 Glue software, BIM 360 Layout software, and Point Layout to retrofit the Autodesk Paris office. After having generated a 3D model in Revit software based on point clouds reflecting existing conditions that we got from 3D scans, we made a retrofit proposal and used BIM 360 Layout software to stake out data into the field with a robotic total station. Finally, we used BIM 360 Layout capabilities to verify the as-built construction and update the model. This session features BIM 360 Layout, ReCap, and Revit. AIA Approved

Renovation work is challenging when you’re trying to capture all the necessary details via hand sketches and pictures to complete the new work with as little field conflicts as possible. This is where the laser scanning of existing spaces is best utilized. Laser scanning enables the design and construction teams to collect 3D color images that, when assembled using ReCap software into a single file, enable users to "walk-through" the 3D space as though they were actually in the space in person. Users are able to navigate through the spaces as well as take relevant dimensions without ever having to get on a ladder or even leave their desks. Laser scanning saves time and provides additional levels of detail that pictures alone can't achieve. This roundtable will discuss how companies are currently utilizing point cloud data along with best workflows to maximize the value provided, along with industry trends. This session features ReCap and ReCap.
Learn how to take existing project information and capitalize on Autodesk, Inc., platforms; ReCap 360 Pro software; Remake software; Revit software; and Maya software—all to create and aggregate models and present information in an immersive virtual-reality setting to derive value for the overall project. The case study we’ll look at is a historically significant, high-visibility project that needed various reality-capture methods to mitigate possible risk and liability during construction. The team was able to use these requirements to drive drone flights, photogrammetric models, and laser scans. These were used to enrich the design models and create an environment to run scenarios for logistics and feasibility studies. The downstream effect will help the owner better understand the complexity and manage understanding of changes as they occur. The created environment will also aid in developing future projects that have similar challenges. This session features ReCap, Maya, and Revit. AIA Approved
