Understanding Zooming to an address
« on: November 20, 2018, 08:19:52 AM »
I was toying around with if there is a way in cad I can type in an address and it would zoom to the location and load the aerial from bing.

So, I also played around with Google Earth and Saved a KML of a location to my desktop.

Through the Insert Ribbon Tab / Location Panel / Set Location (From File) it asks for a KML.

Then the Geographic Location Screen appears.

within the GIS Coordinate System (How do you know which one to Select?) I know I would want feet, EPSG?, but other than that I am not sure.

So I assume a coordinate system, then select next.

On the Command Line it asks for:
GEOCRPHICLOCATION Select a point for the location (0.0000, 0.0000, 0.0000)
***Could someone help explain this step / part of the process for me?***


Thank you very much!!!

I will start you with this one.  The CS (coordinate system) is whatever you plan to do your project in.
For me that would most often  Central Zone, US Foot (AZ83-CF).  So this setting is or should be project specific.

State plane NOT being an option use WGS84


GEOCRPHICLOCATION Select a point for the location (0.0000, 0.0000, 0.0000) - this prompt is technically murky in what it is asking for.
Short answer....IF you had a survey point at a monument, and that data was selectable from the MAP, or imported via 'from file' option
and you have that known point in your file, click on the known point at this prompt, this should align the imported map information with the data already in your file.

From help file:

Select a point
Specifies the point in model space that corresponds to the geographic location you specify in the dialog box. The command places a zoom invariant indicator known as the geographic marker at the point you specify.

You will definetly need a geographic location for the drawing. It would be much easier if you actually assign a cooridnate system (assuming you are using map or civil)
The command is "adesetcrdsys"
One drawing you've sent me in the past used coordinate system code "IN83-EF" - NAD83 Indiana State Planes, East Zone, US Foot

I would do this in lisp using a geocoding service like google maps.
Pseudo Code
  • User inputs address
  • Parse address into format for geocode
  • Send Geocode request
  • Read and parse response
  • Accept first response or give user a list of search results which they can select from
  • Do a coordinate transform on the point
  • Zoom to point

EDIT This appears to be what VOVKA does in his amazing routine http://www.theswamp.org/index.php?topic=47908.0
Cheers, Rod
