  Working with Large Datasets Course Introduction

  (Course Duration: 65 minutes)

   

  Course Description

  In this course, you will learn some strategies, techniques, and tools for working with large Datasets in Civil 3D.  Infrastructure projects commonly use large, data-rich datasets, captured by stationary scanners, and by manned and unmanned aviation aircraft to gain high resolution detail for their projects.  These datasets provide great value to the project, but cripple the performance of CAD systems.  To maintain workable and efficient drawing files there are a number of strategies you can consider, and tools you can leverage to keep your drawing files lean and responsive.  Each project may require a different strategy, or a combination of multiple strategies to achieve the most optimal result.

   

  Course Objectives

  The material presented in this course teach you how to:

  · Import a subset of Survey Points and/or Figures from a Survey Database

  · Import Surfaces from large LandXML files

  · Create Surfaces from large point files

  · Tile large surfaces into smaller more manageable surfaces

  · Simplify large surfaces using Edge Contraction and Point Removal

  · Use Surround and Detailed surfaces to meet resolution requirements

  · Import and Simplify DEM and GeoTIFF files

  · Partition an oversized corridor into multiple smaller corridors

  · Better navigate large drawing files
