Hi everyone,

I'm new to CAM in general and Solidworks CAM in particular (though I've used Fusion 360 CAM a little).
I'm trying to create this multi-surface feature and you can see by the picture what I'm hoping for.

The problem is that the tool path is ignoring the material in the center of the feature.
I'm getting this as a result

It looks like it's doing a contour cut instead of an open pocket.  I've attached my part.  Can someone take a look at it and tell me where I'm getting it wrong on this feature?

Thanks
