Transcription

1 Exporting from GIS 9.0 to AutoCAD Once a map file is created in GIS with all the desired layers, selected data within a pre-defined boundary can be exported as a AutoCAD.dwg file. Setting up clip boundary shapefile Create a new empty shapefile in Arc-Catalog 1. Open ArcCatalog by clicking on the ArcCatalog icon. 2. Select working folder from the left column window. If working folder is not visible, click "Connect to Folder" to select desired working folder then click "Ok". Tip: During current work session, working folder and working files should be saved on desktop to prevent lost of connection with server. 3. Right click on an empty area in the right column window to bring up the pop-up menu. Select "New"; then select "Shapefile". The "Create New Shapefile" dialogue window will appear.

2 4. In the "Create New Shapefile" dialogue box, change the name of the new shapefile (ie: clip_boundary.shp). Spaces are NOT allowed in the shapefile name. Change shapefile type to "Polygon". Click "Edit" to import reference coordinate system. 5. Click "Import" to import a reference coordinate system from an existing geodataset (e.g., feature dataset or feature class). Select destination folder and desired data shapefile, such as building footprint.shp or contours.shp. Then click "Add".

3 6. The "Spatial Reference Properties" dialogue box displays referenced coordinates. Click "Ok".

4 7. Click "Ok" again to close "Create New Shapefile" dialogue box.

5 8. Close Arc-Catalog Open Arc-Map. In Arc-Map, select "Tools" from the top menu bar, then click "Editor Toolbar". 11. Click "Editor"; then select "More Editing Tools"; then select "Advance Editing" to disply the Advance Editing Toolbar.

6 12. In the "Task" pull-down menu of the "Editor Toolbar", select "Create New Feature"; in the "Target" pull-down menu, select "Clip_boundary". Click the "Editor" button on the "Editor Toolbar"; then click "Start Editing". In the "Advance Editing Toolbar", select the "Rectangle Tool". Start drawing the rectangle by clicking once at a corner of your intended clip boundary, then hold and drag to the oppositie corner. Click again to finish drawing the bow.

7 13. To modify the drawn box, select different options under the "Task" pull-down meun.

8 14. When finished modifying the rectangle, select "Save Edits"; then select "Stop Editing". The "Editing" and "Advance Editing Toolbars" may be closed now. 15. In Arc-Map, select "Add Data" to add the newly create shapefile.

9 16. In the "Add Data" dialogue box, locate the working folder that contains the shapefile. If working folder is not visible, select "Connect to Folder" to locate working folder. 17. Locate and select the new shapefile: clip_boundary.shp; then click "Add".

10 Clip data layers within the clip_boundary.shp for export to AutoCAD 1. Open Arc-Toolbox. 2. Select Analysis Tools ; then select Extract ; then double click on Clip". The Clip dialogue box will appear to the right. 3. In the Clip dialogue box, select desired layer in the Input Features pull-down menu. Then select Clip_boundary in the Clip Features pull-down menu. Select your working folder for the Output Feature Class. A new shapefile will be created for your desired layer within that clip boundary area. Click Ok. Click Close when completed.

11 4. A new clip layer now appears in the left window.

12 5. Repeat this step for other desired layers. 6. Image below shows newly clipped shapefile layers with the existing non-clip layers turned invisible. 7. Click to open the Arc-Toolbox. Select Conversion Tools, then select To CAD ; then double click on Export to CAD to bring up the dialogue box.

13 8. Add newly clipped shapefile layers under Input Features. Select output type (DWG 2000/DWG 2004/DWG 2005) and output location and output file name. Click Ok. Click Close when exporting is complete.

14 9. Open DWG file in AutoCAD. Move all layers to origin, 0,0,0, for ease of exporting in Rhino, 3dmax or other modeling software. ----End
