RE: [MI-L] Extracting coordinates of the end points of a line

sorry, ObjectGeography.

ObjectGeography ( object, attribute )

attributes:

1 = minX

2 = minY

3 = maxX

4 = maxY

here's an example QRY file (save as something.qry and load up in the SQL Select dialog)

#################

Fields {ObjectGeography(obj,1),ObjectGeography(obj,2),ObjectGeography(obj,3),ObjectGeography(obj,4)}
Tables {Streets}
Where {}
Group {}
Order {}
Into {Selection}
Browse

#################

ps. if you have difficulty with it returning coordinates to only 3 or 4 decimal places, use Format( yourstuff, "00.000000") or something like that.

the function you want is ObjectNode... but for some reason i can't find it in the MI helpfile....... i haven't used it for maybe the last 2 updates of MI so maybe it's gone...??

Subject: [MI-L] Extracting coordinates of the end points of a line

Does anyone know how to extract the X1, Y1, X2, Y2 of a line to update columns, assuming that X1 and Y1 are the start of the line?

I’m stumped.
