Elements Lists basics

[Anonymous]

The first day of my Elements Lists experimentation I found myself exploring a variety of element lists in a wide number of combinations (by layer, by storey etc).

The next day I have noticed that now the available Lists are only 4 basic ones (basic, doors, windos, default), with all other missing.

What puzles me is that I have never created the first long list of element Lists also the reason they dissapear and wander on the way to bring them back on.

Please excuse my ignorance.

And you'll be noticed, when you open General element list, the volume unit is m2 (square meter), not m3 (cubic meter). And this also appears in volume of object's Element Information pallete.
Something missed with program typing?
