CAD .DWG templates to a specified coordinate location on Earth

Hey Everyone,

My group has a number of dwg files that are multi-vector diagrams of a structure. The final output would be a GDB environment. Writing to a GDB is easy enough but there is no coordinate information attached to it. The template is meant to be placed anywhere we desire on the planet. If there was a center point in the middle of the multiple vectors, is it possible to have FME reference everything to the coordinates point that are supplied by the user?

What you want is called georeferencing. And yes it is possible.

If you only need to move over XY you can use the Offsetter transformer. Set the corrections in the paramaters and you are good to go.

But georeferencing usually involves moving, rotating and scaling. If you also need to rotate and scale you can use the AffineWarper or RubberSheeter transformer.

With those you need at least 4 vectors (from-to lines) to calculate the transformation of the data.

If you prefer to fix this in AutoDesk software, the command is ADERSHEET.
