Can't get 3D morphed spiral to work

[GPTech2444]

I can do a scallop but I can't do a morphed spiral. I get this error,

Warning: Unable to create morphed spiral because a cavity contains more than one core.

Warning: No passes to link.

Here is a screencast of what is happening.

The current morph feature only supports doing morphed spiral between one-to-one pairs of contours. In this case I think that the outermost contour extends so far from the inner contour that morph wants to split it in multiple "pockets". However, we are adding an improved morph which will be able to handle more cases like this. Stay tuned.

That said, in not sure if morph is really what you want here. If the surface is actually flat then you should normally be using Horizontal or maybe 2D Pocket in open pocket mode. Only if the surface is curved it would be appropriate to use Morphed Spiral / Scallop.

The surface at the top of the model is a 3D contour and I've set the bottom level just below that surface so the flat area of the model isn't touched in this step.
The scallop works perfect but I wanted to see if morphed spiral is better.
Thanks.

Try putting a containment boundary around the just the the left boss area.

Thanks Jeff, that sorted it. I thought the bottom level would do the same.
