Presentation Transcript

  1. Working with CAD Data In ArcGIS Travis Wagner

  2. New Features • Adds CAD datasets as group layers • Still have the ability to access all feature types properties and symbology • Better CAD rendering (symbology closely represents CAD drawing) • “CAD unique entity values” in Categories group in the symbology • Can change and then “Restore original” CAD symbology • More support for CAD properties • More fields that give you more information from the CAD drawing (layer information, file type, file path…)

  3. Georeferencing CAD Datasets2 Point Transformation • Prior to 9.2 only supported Raster • 2 Point Transformation(Georeferencing toolbar) • 2 Source points and 2 Destination points • Maintains aspect ratio of CAD dataset • Supports snapping when in edit session • Creates world file (.wld) • Text file of two rows of control point coordinates • Must save it in same folder structure and same file name prefix • Save, create new, or load world file • When you need more than two points use the rubbersheet tool • Can also rotate, scale or shift

  4. Georeferencing CAD DatasetsRubbersheeting • Must convert to feature class • Use Arc Map Spatial Adjustment toolbar • Can use multiple reference points in this tool rather than only two

  5. Demo

  6. CAD Data Translation • CAD to GIS or GIS to CAD • Several Way to accomplish this • Right click on layer and export data • Copy, paste in an edit session • Geoprocessing • Copy features • Feature Class to Feature Class • Append to existing datasets and takes on existing symbology • Import from CAD • Export to CAD (only in ArcGIS Arc Info License Level) • With the use of a Seed File, you can utilize properties or symbology of an existing CAD file • Can export annotation feature class to CAD or override point feature class based on a attribute for text in a CAD file

  7. Demo

  8. ArcGIS for AutoCAD • Free download from ESRI as a plug-in for AutoCAD 2007 adds new menu “ArcGIS” • Imports ArcGIS Server Services • Entire service, data frame or individual bookmarks • Displayed in AutoCAD spatially referenced • Used for background, digitizing and main referencing • Able to control service on or off by toggle the service properties (ESRI_Mapservice) • Can have a cashed service or keep dynamic via properties of service • Allows you to identify map service features by using identify tool • Keeps layer scale dependencies set up in the service (if dynamic) • Keep connection to service if saved if able to keep connection

  9. Demo
