Using manufacturing model for second side, but first model is calculating

[tsquaredesign]

I am new to 2 sided CNC so I am working to find the best practice for this. 
I work in wood on an older Nomad desktop machine. I made the following test part in order to practice programming the top and bottom of a part:

I made a manufacturing model and rotated it 180 degrees in order to develop the paths for the bottom side. However, the paths continue to calculate the top surface even when that model is turned off. 

I'm sure I missed something, but I'm not sure what. 

Thanks

Have you checked the orientation of the work coordinate system?  Usually when this occurs the Z is pointed down.

I thought by rotating the machine model I was able to keep the Z axis pointing up? That's why i made two (2) manufacturing models, one up and one down. Then I turned "off" the MM that I was not using.

I think you might have a slight misunderstanding on how multiple Setups should work in Fusion. There's typically no need to duplicate models or Manufacturing Models. 

Create 1st Setup, assign Stock and WCS location

Create all toolpaths for that Setup

Create 2nd Setup on the opposite side, select "From Preceding Setup" and select "Continue Rest Machining". Designate your WCS value and location.

Create toolpaths as needed.

Well, it has taken me most of the day, and a few crashes to understand your approach. I cannot thank you enough for your help and support as I learn. 

I just heard back from AutoDesk, and it appears that multiple manufacturing models is a "no no". Didn't know that. Your approach is much more direct.

Hi @tsquaredesign - who steered you away from multiple manufacturing models?

We usually steer people away from manufacturing models due to limitations with them, but they have value. There's nothing in particular problematic with having multiple of them, depending on how you use them. It sounds like, though, in your situation, it's not necessary.

Thanks,

I think you are correct. I overcomplicated the strategy unintentionally. 

thanks again for all your help.
