new elements are associated with the section specified on the AATT command. The section specified
by the SECNUM command is ignored.

16.2.7. Using the Shell Tool to Create Sections

Figure 16.2: Shell Tool With Layup Page Displayed
The top part of the Layup page of the ShellTool relates a section ID number to a Shell section type
(and, optionally, a section name) [SECTYPE]. The middle part of the page of the ShellTool defines each
layer in the positive Z direction of the element [SECDATA]. Note that the order of the rows in the
spreadsheet ascends up the page, resembling that stacking of the layers. (Integration point data for
each layer is ignored by thermal shell elements.) The bottom contains the fields for section offset in-
formation, if needed [SECOFFSET]. You can define tapered shells by specifying a section function relating
thickness to global coordinates [SECFUNCTION].
