Hello,

I normally work on British Ordnance Survey coordinates in meters. I've been sent a drawing where the coordinates appear like this:

3.5230E+08,1.7998E,

can anyone tell me what this means? the drawing is in mm.

Cheers
Dave

the X coordinate is 352,300,000 (3.5230 x 10 to the 8th power), I'm not sure about the Y coordinate, it seems to be missing an exponent, probably 1.7998 (1.7998 x 10 to the 0 power). This is scientific notation, it can be changed using the Units command.

AutoCad is just lazy.... I read it as 3.5230 x 10^08 that is 3.5230 x 10 000 000 00 ... it's just too big numbers for AutoCad to print out...

damn, too slow again! :glare:

ah, i mistyped the 'y', it should read 1.7998E+08.

thanks guys
