which shape type (dynamic/static) to be used in negative power planes?

Q1. which shape type (dynamic/static) to be used in negative power planes and why?

    Negative planes still have their place in some designs and if you continue to use them I would recommend using Dynamic shapes.

    Why? Dynamic shapes will automatically void any Route Keepouts on the layer (For example, Keepouts around mounting holes) while pins and vias will continue to use geometries defined in the Padstack.

    Hope this helps,
