On rare occasions I come across a coordinate system which is non-standard and can cause the user some headaches.  Recently Igor, a Pointools user, had a dataset with a left-hand coordinate system which when imported and converted to POD caused it to appear mirrored. 

I did some work with a surveyor from Singapore some years ago and remember that they use a LHS coordinate system, which we could compensate for while on site, i guess it is normal in some countries. 

To correct this in Pointools is quite simple.  Just figure out which axis the POD is mirrored on and scale the POD by -1 in that axis:

• select POD in Object Tree
• scroll down to scale input boxes in Properties window
• change value in box to -1 (the 3 boxes represent X Y + Z in that order)

Once this is done go to Export and create a new copy of your POD with a unique name.
