  • Historically, architects and engineers have used CAD, CAE, and more recently BIM that worked in separate environments from GIS users. CAE or Computer-Aided Engineering refers to engineering technology involving modeling, analysis, simulation, and design often used in manufacturing and other areas involving components and assemblies
  • Engineering data – new road centerlines or curb lines, utility alignmentsMap data – property data, wetlands, soil types
  • CAD can directly read GIS data, including properties and transformed according to GIS. No translation required.
  • 3D support refers to the new feature of selecting a property that stores the Z value and setting the feature to that elevation. Very useful for contours.
  • CAD can directly read GIS data, including properties and transformed according to GIS. No translation required.

    10. 10. Translate if necessary, but not necessarily translation.<br />Direct access<br />CAD<br />GIS<br />
    11. 11. Bentley’s Approach<br />Add tools to consume GIS features<br />Coordinate systems<br />Attribute data<br />Tools to read the various formats<br />(SHP, MID/MIF, ODBC, TAB, WMS, Oracle Spatial)<br />3D support (set elevation)<br />Users can now import or reference GIS data directly with on-the-fly coordinate conversion and full access to attribute data<br />
    12. 12. Export to GIS<br />Export<br />CAD<br />GIS<br />
    13. 13. Bentley’s Approach<br />Add tools to specifically define GIS feature types within the CAD model<br />Point, line and polygon types as well as collections.<br />Attribute data<br />Tools to export the various formats including attributes and coordinate systems<br />Users can now export CAD data directly.<br />Basic CAD features or well defined GIS features<br />
    14. 14. Improving CAD-GIS Interoperability<br /> - Transfer only required data<br />- segregate features destined for GIS on separate level<br />- make sure only one feature type is on a GIS level<br />- set a high stroking tolerance that achieves a good result<br />- if using property data, maintain simple property types<br />
    15. 15. Other tools<br />Automatic feature recognition<br />Treats CAD elements as GIS features<br />Apply symbology based on attributes<br />Application integration<br />Tools make GIS data available for civil, building, infrastructure applications<br />Server level<br />Integrate directly with Oracle Spatial and ESRI Geodatabase<br />Publish data as WMS and WFS<br />Index and manage files spatially<br />
    16. 16. HNTB<br />Multidisciplinary engineering firm based in Kansas City<br />Use primarily geocoordination and interoperability tools to support MicroStation projects<br />Set GCS (geographic coordinate system) for designs<br />Import or reference SHP data<br />16<br />
    17. 17. Benefits - HNTB<br />Define GCS<br />simplifies output to Google Earth for visualization<br />Simplifies working with GIS data which invariably has a defined GCS<br />Interoperability<br />No need to go to GIS group to import SHP and create DGN<br />Work in design environment with minimal training<br />Add on features<br />Thematic mapping, overlays, buffers<br />17<br />
    18. 18. Port of Long Beach<br />Second busiest port in the United States, moving $100 billion annually<br />Manages all infrastructure for the port<br />Water, storm water, sewer and lease areas stored in ESRI geodatabase but maintained by Bentley Map using Connector for ArcGIS<br />Some layers still maintained in DGN<br />Regular extract from geodatabase to produce up-to-date base map for engineering<br />18<br />
    19. 19. Benefits – Port of Long Beach<br />Bentley Map the preferred tool for maintenance<br />Maintenance tools and base maps all match defined CAD standards<br />Improved workflow<br />Similar tools for design and engineering<br />Can reference as-built drawings in maintenance process<br />Interoperability with SHP and AutoCAD<br />Bentley Map part of an enterprise system including ESRI Geodatabase and Geospatial Server.<br />19<br />
    20. 20. Demonstrations<br />Import SHP<br />Bring in GIS data to solve a problem in CAD<br />
    21. 21. Conclusion<br /> GIS and CAD integration does not have to be seen as an impossible task. Through the use of standards and data management, information can travel freely between the two diciplines. This eventually leads to tremendous savings in both software and more importantly time.<br />
