5 Class Narrative 1. A competitive advantage exists within the ability to effectively market the process of a product. 2. The most effective way to communicate the process is through technical visualizations.

6 Key learning objectives At the end of this class, you should be able to: 1. Quickly Develop Conceptual Models for Proposals 2. Use Civil 3D for Model Based Design 3. Incorporate AEC Models to Market the Process of Modern Design This class incorporates the following tools: 1. InfraWorks 2. Civil 3D 3. 3DS Max Design

7 Introduction Notes Create visualizations as a means of telling a story Reference existing media for guidance Movies, commercials, art, CG Architect, etc. Use existing content surface model, aerial imagery, buildings, etc.

8 Introduction Notes Import content from real world sources Existing Buildings, cars, road, colors from image samples Emphasize the source of the model Architectural/Engineering final design content Proposed

9 The Purple Pipe Project

10 Purple Pipe Video

11 Purple Pipe Project Data

12 Purple Pipe Construction Facts Construction of 16,000 feet of 20 and 36 pipe from NCPCP to the Covanta Energy Resource Recovery Facility 7,000 feet of 12 pipe to the Laurel Hill Golf Club

13 Purple Pipe Sustainability Facts Sustainability Benefits Reduce nutrients discharged to the to Chesapeake Bay Preserve 2 MGD Drinking Water Improve drought resistance Offset treatment costs

14 Purple Pipe Technology Use of Civil 3D for pipeline design and existing utility conflict detention Successfully completed construction of 4+ miles of pipeline in ultra-urban region without single conflict

15 Purple Pipe Workflow Available base data to develop proposal design GIS Based Proposal Graphics and complimenting video Civil 3D pipe/road tools to model existing utilities and proposed pipeline Civil 3D Pipeline Design 3ds Max Design and Civil View to show final engineering design 3ds Max Design Engineering Graphics

16 I. InfraWorks - Preliminary Design & Visualization

17 Preliminary Design and Visualization InfraWorks allows for an efficient means of compiling data (GIS, CAD, imagery,) and allows for rapid production of design concepts. Visualizations of this data during project proposals is used to demonstrate an understanding of existing conditions and to show innovative solutions.

18 GIS Content Quick Overview GIS is simply a geometric Geometry (line, point, polygon) shape with data (like an excel sheet) attached to the shape. GIS GIS files come in multiple format types, with the Attribute Data (name, size, date) most common as.shp file Typical to link to data, as opposed to import

19 Recommended Existing Base Data (GIS) Surface Data Contour/Breakline/Point.shp C3D to IMX File Aerial Photography mrsid files tiff with World File (.tiff &.tfw) Buildings Footprint.shp Files

20 Supplemental Base Data (GIS + Models) City Furniture Points of interest.shp files (utility poles, traffic signals, etc.) Landmarks from SketchUp Warehouse or self authored Utility Information Pipes and structures from.shp files Civil 3D networks (.IMX)

21 Proposed Improvements Design Pipeline Export alignment line to.shp and set as barrier Alternatively, use Alignment object an export.imx Annotations 3D Text objects (imported as models from CAD, 3ds, etc.) Additional Linework MAPEXPORT -.shp

22 Cinematography Tips Begin with comprehensive view Long slow scenes Rely on aerial imagery Avoid showing the edges of the model Standard HD (720p).wmv format (15,000 kbit/sec)

23 Live Presentation Option InfraWorks Models can be exported for web/ipad based viewing Free motion of content, low quality and limited settings Consider video backup

24 InfraWorks Video

25 II. Civil 3D Final Design

26 Pipeline Model Based Design All infrastructure components should be Civil 3D objects Horizontal Pipeline Vertical Pipeline Appurtenances Pipe Trench Existing Utilities Aerial/Field Topography Pipeline objects are interpreted as Civil 3D objects shown below Alignment Object Profile Object Pipe Network Assembly / Corridor Pipe Networks Surface with Edits/Paste

27 Civil 3D Visualization/Design Optimization Pipe Networks Existing utilities created as Pipe Networks Assumed depth for nongravity systems (adjust at test-pits) Proposed utilities created as Pipe Networks Gravity and non-gravity utilities as applicable (Pressure Pipe Networks do not export) The non-gravity utility designations typically come in as 2D linework. Assign elevation by existing surface (no intermediate grade break) Convert object to pipe network, merge networks Convert to feature lines Lower feature line to assumed depth Alternative: create pipe network with depth rule min=max

28 Pipeline Design (as Road Design) Plan View Waterline bends as PI Labels to show deflection angle, station, n/e Based on standard bend angles (11.25, 22.5, etc.) Horizontal Curves Labels to show start/end station, radius

29 Pipeline Design (as Road Design) Profile View Vertical Bends as PI Labels to show deflection angle, station, n/e Based on standard bend angles (11.25, 22.5, etc.) Vertical Circular Curves Labels to show start/end station, radius

30 Pipeline Design (as Road Design) Equivalent Radius R = L 2[tan( 1 2 )] L = pipe stick length = MAX deflection Equivalent Bend (Vert.) 100*ABS[ATAN({Grade In}) - ATAN({Grade Out})] Pipe Size Allowable Deflection Max Design Deflection Pipe Length Equivalent Radius A (Grade Change) Equivalent Bend 9.85% % % % % % 60

31 III. 3ds Max Design - Visualization

32 Advanced Visualization Video

33 Export From Civil 3D Pipes Supported on export. If using the road tools for pipeline, create featureline from alignment, then pipe from object Surfaces Supported on export. Ensure no overlapping surface by using boundaries

34 Coordinate Notes Global Shift Importing a Civil View file will automatically apply a global shift to the data to account for geo-coord Each new imported file will relate to that shift Two separate Max files importing from the same Civil 3D file, may not have the same shift

35 Coordinate Notes Basic AutoCAD objects are not currently supported to be exported and shifted. Use featurelines (supported under Sites) to allow for reference building footprints, property lines, etc.

36 Other Model Content Buildings Basic outlines with extrusions (distance) Simple Revit models Site Features Export.FBX from InfraWorks for a good library of homes, power poles, cars, trains, bridges, etc.

37 3ds Max Design Base Settings (Preferences) Mental Ray render Reduce most settings unless you see a noticeable difference mr Photometric Exposure Set Exposure Value to 14 Civil View Daylight Create daylight system from Civil View explorer

38 Render Formats Always render to images (.bmp), never to video files Each frame can take 5+ minutes (23.96 frames/sec) and an issue with a single frame will cause you to rerender the entire video VirtualDub (or AE) compiler to convert images to video

39 Lighting The sun is bright, and complicated If you want objects to glow, the light intensity has to be as high as possible to compete with the sun Photorealistic lighting takes a lot of resources, but will provide the best visuals Add lens flares in post

40 Additional Visualization Tools GIMP 2 Before After Used to edit aerial imagery, remove flat features with clone tool Cars Bridges Power Lines Aerial image location is referenced, so do not change rotation, crop, or size of image

41 Additional Visualization Tools Forest Pack Pro Along with a good tree library, can allow for quickly creating a mass of proxy objects Create libraries of Revit based buildings to create neighborhoods 3ds Max can import Revit

42 Post Production Microsoft Expression Encoder 4 (free) Combine, trim,.avi to convert to.wmv Adobe After Effects Consider Game Engines

43 Helpful Values Aspect Ratio 16:9 (wide screen) 720p: 720x p: 1080x1920 Frame Rate 24 = FPS Exposure mental ray photometric 14 Daylight Adjust location in daylight system, and time/date based on aerial imagery
