1Using AutoMap 3D to create a shapefile Using RAM 148Daryl Hines
2The Source CAD FileIt is your decision whether to make any changes to the layer structure in your current CAD template.The object is to select and attribute only a few elements from your CAD drawing and export them as a shapefile.If placing these features on different layers, renaming layers, or establishing any other standards that facilitate an eventual export, copy, or save down into this separate DWG will speed or enhance this process, then you might make these types of modifications to your CAD workflow.Your challenge is to make this process as seamless and easy as possible.How you, as CAD operators, get to this point is up to you, as only you know what will work best within the CAD framework and software you operate with.Today is a good time to share your expertise and experience with others.
3Considerations before beginning Export to Kentucky Single Zone Coordinate SystemContain only the following:Proposed BoundaryCurrent Approved BoundaryFillsPermanent ImpoundmentsHaul RoadsBonding Increment Boundaries (if applicable)All export features must be closed polygon elements.For haul roads, the polygon area would be the right of way edges but if the roads are polylines these could be buffered into polygons.Need to exclude non-permitted areas (create donuts).Create or use template provided for object data table?
7Assign your Coordinate System (for this drawing KY83F) ADESETCRDSYS
8Assign your Coordinate System to your drawing (remember this does not transform the drawing) ADESETCRDSYS
9nextThe exported features need to be closed polygonsFIX
10Closing features The exported features need to be closed polygons…. In PROPERTIES are polylines set to “closed”?
11next gas wells, cemetery? If there are areas within the permit boundary that are not permitted then they need to be excludedgas wells, cemetery?
12Creating polygon with islands, holes, or discontinuous polygons Use PROXYGRAPHICS, GROUP, and MAPPOLYLINETOPOLYGON commands1st Set the PROXYGRAPHICS system variable to 0 (does not save image with the drawing; a bounding box is displayed instead)
13Creating polygon with islands, holes, or discontinuous polygons Select inner and outer polygons to groupUse Group commandName GroupSelect polygons
14Creating polygon with islands, holes, or discontinuous polygons Select the group and then; MAPPOLYLINETOPOLYGON
15Looking back and moving along Assign current coordinate system (ADESETCRDSYS)The exported features need to be closed polygons (PROPERTIES)If there are areas within the permit boundary that are not permitted then they need to be excluded (PROXYGRAPHICS, GROUP, and MAPPOLYLINETOPOLYGON)Attributes need to be assigned. Use template or create object data table?We will look at creating a new one first.
