I'm just wondering if I'm missing anything? Does anyone else have a need for this?
I often want to make a 'surface box' but haven't a nice way in a single feature.
For Revolves it works great, not so for extrude
I know a work-a-round but it's PITA
Hopefully someone has a better solution but if not I would consider it a useful enhancement request to have an extra checkbox in the property manager akin to knit surface.
In my mind Surface Extrude should always create a surface. Why duplicate the behaviour of Boss-Extrude?
