Three options of slice extraction are available in Tecplot 360. This video will describe when you should use each.

The first of the three options is which slice group you would like to extract from. In previous versions, only the currently active slices could be extracted. With the Extract by Group option, you can now extract slices without toggling them on and requiring additional steps of loading and drawing.
The next set of options allows for extraction to a single zone (the default in previous versions) or to separate the extraction regions depending on the connected regions. In this case, connected regions include zone boundaries where the slice goes across multiple zones, or when a single zone has distinct regions such as flow through a nacelle, or a wing with multiple sections.
The final new option only applies when extracting from a surface. This option makes an attempt to save the extracted zone as an ordered zone, as opposed to the previous default of an FE-line segment zone. By ensuring the resulting zone is ordered, this allows additional analysis to be performed within Tecplot, and connecting with data and scripting tools such as PyTecplot and Matlab.
