OVERVIEW

• 3D MODELING
• Hardware Needs
• Video Card (256 MB)
• RAM (2 GB)
• Processor (2.5 GHz)
• Software Needs
• ArcGIS Desktop with ArcScene
• 3D analyst extension
• Movie editor
• Data Needs
• Contour (elevation) data
• DGN, DWG, SHP, ETC.
• Preferably polylines
• Features Data
• Preferably polygons
• Aerials
• JPEG, TIFF, IMG, ETC.
• Preferably JPEGs

Project Example
4
1) START WITH A 3D CAD FILE ( OR ANY OTHER DATA
FILE THAT CONTAINS ELEVATION VALUES RECORDED FOR
EACH LINE).
5
2) EXPORT THE CONTOUR POLYLINES TO A SHAPEFILE.
6
3) CLIP THE CONTOUR SHAPEFILE WITH THE CUT/FILL
BOUNDARIES FOR THE PROPOSED ALIGNMENT.
7
4) COMBINE THE CLIPPED CONTOUR SHAPEFILE WITH THE
PROPOSED ALIGNMENT CONTOURS.
8
5) CONVERT THE COLLECTION OF CONTOUR SHAPEFILES
TO A TIN USING THE 3D ANALYST EXTENSION.
9
6) ADD 3D FEATURES SUCH AS TREES, UTILITIES,
VEHICLES, STRUCTURES, ETC. USING ArcScene 3D
SYMBOLOGY.
10
7) DRAPE AN AERIAL PHOTO USING THE TIN AS THE
BASE HEIGHT.
11
8) ADD FEATURES FOR THE NEW ALIGNMENT USING THE
TIN AS THE BASE HEIGHT.

SUMMARY

• START WITH A 3D CAD FILE (OR ANY OTHER DATA FILE
  THAT CONTAINS ELEVATION VALUES RECORDED FOR EACH
  LINE).
• EXPORT THE CONTOUR POLYLINES TO A SHAPEFILE.
• CLIP THE CONTOUR SHAPEFILE WITH THE CUT/FILL
  BOUNDARIES FOR THE PROPOSED ALIGNMENT.
• COMBINE THE CLIPPED CONTOUR SHAPEFILE WITH THE
  PROPOSED ALIGNMENT CONTOURS.
• CONVERT THE COLLECTION OF CONTOUR SHAPEFILES TO A
  TIN USING THE 3D ANALYST EXTENSION.
• ADD 3D FEATURES SUCH AS TREES, UTILITIES,
  VEHICLES, STRUCTURES, ETC. USING ArcScene 3D
  SYMBOLOGY.
• DRAPE AN AERIAL PHOTO USING THE TIN AS THE BASE
  HEIGHT.
• ADD FEATURES FOR THE NEW ALIGNMENT USING THE TIN
  AS THE BASE HEIGHT.

VIDEO SIMULATIONS

• Use model and animation toolbar to capture video.
• Create animation file of keyframes
• Series of camera positions
• Export to video
• Captures a video based on the preselected
  keyframe (camera) positions
• Must select a video file type
• Must select a codex to compress the video
• Can create an uncompressed video but the file
  size will be enormous
• Edit video
• Combine video clips and add captions using any
  video editing software available
