Trying my luck at Aspire and having some problems with tool paths and the model I've designed... its a dished model.

After creating a roughing tool path it appears to me that the milling starts above the model and I'm not sure where or how to set it to "Z" Zero.

Can anyone confirm this for me from the images I've attached?

I'm assuming that the "Red" line indicates Z zero in the model, green lines Z up and Z Down and the blue lines X and Y movement.

Adam,
