Our school just got our master cam program working. When I generate g-code it always has the Z in a positive position instead of a negative. Any help appreciated.

I should note also I am inporting directly from Autodesk Inventor to Mastercam X.

You haven't given enough info to diagnose your actual problem
pics would help
maybe a comment as to what you should expect in the code

Go to the FRONT view
- Where is the toolpath in relation to the part ?
&
Where is the part in relation to the Z0 datum line ?

If you have worded the question wrong, and want to know why it is not using arcs
look at the filter tab ( enable arcs in XY plane )-may have to go deeper,( into the control file ) if this doesn't fix it.

Most likely simple case of z zero not set properly. Or incremental value in depth field.

Screenshots would surely help.
