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.

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

Key learning objectives

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.

I. InfraWorks - Preliminary Design & 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.

Preliminary Design and Visualization

GIS Content – Quick Overview

Geometry (line, point,

polygon)

Attribute Data

(name, size, date)

GIS

GIS is simply a geometric shape with data (like an excel sheet) attached to the shape. GIS files come in multiple

format types, with the most common as .shp file Typical to link to data, as

opposed to import

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

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)

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

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)

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 https://infraworks360.autodesk.com/portal

II. Civil 3D – Final Design

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

Civil 3D Visualization/Design Optimization

Pipe Networks Existing utilities created as

Pipe Networks Assumed depth for non-

gravity 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.

Convert to feature lines

Assign elevation by existing surface (no intermediate

grade break)

Lower feature line to assumed depth

Convert object to pipe network,

merge networks

Alternative: create pipe network with

depth rule min=max

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

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

III. 3ds Max Design - Visualization

Advanced Visualization Video

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

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

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.

Coordinate Notes

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.

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

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 re-render the entire video

VirtualDub (or AE) compiler to convert images to video

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

Additional Visualization Tools

Before After

GIMP 2 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

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

Post Production

Microsoft Expression Encoder 4 (free) Combine, trim, .avi to

convert to .wmv Adobe After Effects Consider ‘Game Engines’
