2. © 2012 Autodesk Class Summary Laser Scanning and Point Clouds are a hot topic and in this session we will be covering what Laser Scanning is, show the full working details. Moving right into what point clouds provide to you, managing the expectations and following the data workflow from capture (start) to use (finish) and where you can take advantage of using the Scan to BIM product with Autodesk Revit to streamline the workflow, literally from Scan to BIM. This will be a full overview taking you through the process with time to get your questions answered in one location.

3. © 2012 Autodesk Learning Objectives At the end of this class, you will be able to:  Learn first hand what the cutting edge of scanning is doing (and how a scanner works)  Identify where laser scanning may be a fit for your project  Understand & manage expectations when working with Point Cloud data  Leverage tips on what to do, what to avoid, where potential issues may arise and how the latest techniques can benefit you

5. © 2012 Autodesk Module 1: What is a point cloud A point cloud is a set of vertices in a three-dimensional coordinate system. These vertices are usually defined by X, Y & Z coordinates, and typically are intended to be representative of the external surface of an object.

6. © 2012 Autodesk Module 1: What is a point cloud Point clouds are most often created by a 3d scanner.

7. © 2012 Autodesk Module 2: Capturing Data

8. © 2012 Autodesk Module 2: Capturing Data These devices measure in an automatic way a large number of points on the surface of an object, and typically output a point cloud as a data file. The point cloud represents the set of points that the device has measured.

9. © 2012 Autodesk Scanners need to have visible targets in order to be able to assemble different scans into one unified point cloud. Targets appear in more than one scan, so that the scans can be stitched and registered together. Module 2: Capturing Data

10. © 2012 Autodesk Things to Consider

11. © 2012 Autodesk Scanning: Up-Front Requirements  What are you trying to get out of the scanning project?

12. © 2012 Autodesk Scanning: Up-Front Requirements  Number of Points Modern scanners are able to collect an overwhelming number of points What amount(s) are useful/necessary for the modeling process?  Origin/Orientation Meaningful location on building/property? GIS-based / State Plane coordinates?

13. © 2012 Autodesk Scanning: Up-Front Requirements  What’s the nature of the building? Square Footage General Shape/Features (box? Gehry-esque?) Open floor plan? Closed Rooms? Conditions (empty, occupied, access/permission to spaces, roof, etc)? Old? New? Materials? Brick, Metal Wall Panel, other?

14. © 2012 Autodesk Scanning: Up-Front Requirements  What kind of modeling is planned? Basic walls/doors/windows/openings? Piping/Ductwork/Structural Elements Stairs/Railings? Ornamental Details (crown molding, custom casework, etc)  What kind of modeling accuracy am I attempting to get? What defines modeling accuracy for you? For out-of-plumb walls: I will do profile (90 deg) walls, and test that deviation is “not too bad” I will create mass walls to model exactly Content: creation of instance-based doors, etc? Documentation of discrepancies

15. © 2012 Autodesk Scanning: Up-Front Requirements  Planning to capture MEP data? Mechanical Rooms? Above the ceiling? (you’ve just doubled your square footage) Ease of access / removing tiles / etc?  Hardware / Logistics How are point clouds being stored, delivered, archived?

16. © 2012 Autodesk Module 3: I Have Point Clouds Now What?

17. © 2012 Autodesk You can use the point clouds to create a Building Information Model Module 3: I Have Point Clouds Now What?

20. © 2012 Autodesk Module 6: Tips and Techniques

21. © 2012 Autodesk  Segment the model and the point cloud Levels Areas of the Building Key Sections Manage the point-count  How Much Detail?  Balance Distance with Detail Tips and Techniques

22. © 2012 Autodesk  Preparation Content Styles/Creation Finishes / Materials  Modeling Process Establish Building Location/Orientation Organize Revit Models Early: Levels by Sectioning Use Reference Planes Walls -> Openings -> Floors -> Roof Tips and Techniques
