Using AutoMap 3D to create a shapefile Using RAM 148 Daryl Hines
The Source CAD File It 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.
Considerations before beginning Export to Kentucky Single Zone Coordinate System Contain only the following: Proposed Boundary Current Approved Boundary Fills Permanent Impoundments Haul Roads Bonding 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?
Assign Coordinate System Because if you will be exporting to Ky Single Zone (ft) the software needs to know your current coordinate system ADESETCRDSYS
Assign Coordinate System ADESETCRDSYS
Assign your Coordinate System (for this drawing KY83F) ADESETCRDSYS
Assign your Coordinate System to your drawing (remember this does not transform the drawing) ADESETCRDSYS
next The exported features need to be closed polygons
Closing features The exported features need to be closed polygons…. In PROPERTIES are polylines set to “closed”?
next If there are areas within the permit boundary that are not permitted then they need to be excluded
Creating polygon with islands, holes, or discontinuous polygons Use PROXYGRAPHICS, GROUP, and MAPPOLYLINETOPOLYGON commands 1 st Set the PROXYGRAPHICS system variable to 0 (does not save image with the drawing; a bounding box is displayed instead)
Creating polygon with islands, holes, or discontinuous polygons Select inner and outer polygons to group Use Group command Name Group Select polygons
Creating polygon with islands, holes, or discontinuous polygons Select the group and then; MAPPOLYLINETOPOLYGON
Looking 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.
ADEDEFDATA So, we need to end up with a table that looks like this within GIS software..
Define Object Data Command ADEDEFDATA
ADEDEFDATA Table name is up to you
ADEDEFDATA Table name is up to you
ADEATTACHDATA Now that we have the object table’s fields it’s time to select the objects and attach the table
ADEEDITDATA At least two ways to edit object data, to add permit information.
ADEEDITDATA Select all of the objects that will be attributed
ADEDITDATA In the value box type in the appropriate information for each field that applies.
Second method is to use the PROPERTIES command. Select object and type in values. This is a good way to attribute many objects at one time!
Add object data. Hit the enter key after each update
MAPEXPORT Now that we have attributed the objects it’s time to export them out as a shapefile..
1 st name it correctly; example ( _NW or _AM_3) and.shp extension
MAPEXPORT 2 st choose polygon
3 rd Coordinate conversion if necessary. Type in KY83F if not already in KY83F. 4 th Treat closed polylines as polygons? May be useful to your business needs. NAD 83 Kentucky Single Zone US Feet
Select objects to export Several options; choose the one that is best for you.
Check your work..
Use free ArcGIS Explorer to check work? lorer/index.html lorer/index.html
ArcGIS Explorer (free)
Add your shapefile data here
Right mouse click for “Properties”
Mouse click on map to open table
Using a template with the object table Open map template Use INSERT command to add your drawing Use “locate using Geographic Data” option
Attach Object Data (supplied with the template) Use ADEATTACHDATA command Select objects to attach
Now you are ready to edit object data using ADEEDITDATA back in slide 24…
