Request - UV indicator during surface preview to assist with setting number of spans in U and V directions. Currently the only way to know the directions is to start changing the number of spans and look for whick way spans are being changed.
RH-94459 Patch: UV indicator
As requested many times in the past, any command for editing or building new geometry that affects the structure of a surface should automatically evoke UV indicators (and even N if the normal direction is changed).
