That's why in the German version we are advised to draw the gross volume with morphs.
But I agree it is a bit weird that we can't get the gross volume (it just shows "---" in a schedule) – my guess it's because Archicad could not differentiate between a legit SEO/roof-cut and one that should be disregarded for the gross volume.
Through national regulation we have to extract gross and net volumes / areas based on the ISO 9836 standard. In Germany I believe it is the DIN 277 norm they have to follow. Both have a lot in common.
True, right now we can not schedule all these areas and and volumes using ther zone tool. We also use morphs for gross volumes and fills for gross areas. Both are workarounds, but we have it all streamlined and it does give us everything we need for our Schedules.
But this workarounds do require extra manhours and I would be very happy if the zone tool would be upgraded in a way, so we could extract all these data into schedules without the extra work.
