Latitude/longitude not working ?

Didier Bur

Hi all,

Has anyone ever got this working (out from the su-ruby api doc) ?

Assuming you have set the georeference of your model in the Model Info dialog:

coordinates = [10, 10, 10] # or whatever coordinate...
model = Sketchup.active_model
point = Geom;;Point3d.new(coordinates)
latlong = model.point_to_latlong point
latitude = latlong.latitude
if (latitude)
UI.messagebox latitude
else
UI.messagebox "Failure"
end

It doesn't return a latlon object, but a point3d object. And I need a latlon...

Help greatly appreciated !

The 3D point it returns is in the format 'long/lati/height'.
The 'X' is the longitude in degrees [actually it's in 'inches'!]
The 'Y' is the latitude in degrees [actually it's in 'inches'!]
The 'Z' is the point's height in inches.
To return the long/lati use
latlong = model.point_to_latlong(point)

(55, -1, 0) - this is for the 'ORIGIN' where I live...
To set it as 'degrees' - for use in other methods you can use...
long = latlong.x.to_f lati = latlong.y.to_f high = latlong.z.to_l [in current units]
-1.0, 55.0 and 0.0
You can then use
ll = [lati, long]

Note how perversely it takes 'lati/long' in the reversed order from the 'point' itself!

my_ll = Geom::LatLong.new(ll)

LatLong(55.00000N, 1.00000W)
my_ll.latitude >>> 55.0
my_ll.longitude >>> -1.0
It's not the easiest or most logical method in the API!

Thanks a million TIG
