Yeah, just create the VecScatter however you like.

Hello,
I have a DM and its vector for a structured 3-D domain and trying to
extract the data for a 2-D plane. I did some research on the manual and
noticed there is function named DMSlicedCreate(), however, it is for
unstructured problem. Is there any ohter function to extract vector for
