How to get the correct coordinate of a path when i use bindkey 'q' && use car(geGetSelSet())~>points ?

Hi All ,

I draw a hori path which coordinate Points = (10099.045 122.01) (10103.915 122.01) when i use 'Edit Path Properties' to display

But when i use car(geGetSelSet())~>points , in CIW , it returns ((10099.05 122.01) (10103.92 122.01))

when i use the points to do something , it gets wrong result.

But when the path moved to (9737.795 122.01) (9746.925 122.01) => the result is correct.

It seems the points will be truncate or round when path at large coordinate .....

Thank you,

Charley

Charley,

The database itself has the full precision - it's just the default print representation in the CIW that is limited to 7 significant digits. You can use the fullPrecision switch to change the default display to using 14 digits:

> 12345.123
12345.12
> a=12345.123
12345.12
> a-12345.12
0.003
> sstatus(fullPrecision t)
t
> a
12345.123

Regards,

Andrew
