VTL C axis Zero Setting

[@Mastercam]

Hello Gents,

How to change c axis zero position in VTL?

In default VTL post  C axis zero is at 9 clock when looking from top. But I need to change this position to 3 clock. I've attached .Mcam file also

If anyone know kindly assist me to that.

Are you using a Mastercam Generic Post that is looking to the LMD? If you you have a setting in there to control this.

Go in the LMD (Lathe Machine Definition) and set the start angle for the C axis 90 or -90 and see if that helps.

Take you [top-1] plane and rotate it 90 degrees and regenerate the operation. I got this:

Generic post might not give you what you need. I am afraid you going to have to reach out to your dealer and get a custom post for what you need. I tried switches in the post and nothing seemed to give me what your after. I haven't messed with post in years I leave it to the professionals and focus on other work.

By Rotating  plane is a secondary solution. 
In Generic post C zero is at 12 clock position for Lathe - Looking from front  &  For VTL C  zero at 9 clock position - Looking from Top .  But i need this C zero at 3 clock position.  
so i made change in MD  c-axis but it is not working.

For reference, I've attached some of images...….
