T/C plane should be TOP not RIGHT. Post your file here so everyone can see it.

if you are on the main spindle WCS should be TOP ( +D+z ) tool plane and construction should be RIGHT SIDE and since you are using G112 your rotary axis should be set to C axis

Do you have your geometry broken so the post will do this correctly? If you go past center line on some post it will go crazy. Also if you do not draw your lines in the correct view and start and end them the right way the post will go crazy. Could send it over to Mike he would pop it in Catia in about 4 seconds.
