About Shells

Note: You can edit a selected composite by accessing its settings from its context menu:
Use Flip (from Shell Settings or the Info Box) if you want to move the Shell body to the other side of Shell membrane.
See Create Hole in Shell and Skylights.
ARCHICAD’s Gravity feature works on Shells. That is, when placing a new Wall, Column, Beam or Object-type element, the Gravity function lets you place it directly on top of an existing Shell, thus taking on the elevation of the element it is placed on.
