VCarve Pro doesn't include an auto-panelling option.
We do have customers who have split large designs into smaller machinable projects by using the Weld and Node Editing Tools in VCarve Pro. By drawing rectangles the size that can be machined over the top of a large design and using the Weld Merge and Subtract tools.
The Layers control helps with this process, and I would place a copy of the complete design on each layer along with a rectangle for each segment. Then edit the design to leave each smaller segment on each layer.
This sounds tricky, but with practice it can be done quite quickly.
I hope this makes sense and helps,
