D.4 Cross Section

Each shape can be cut out and folded along the dashed lines. If you fold all the fine-dotted lines in one direction, and the coarse-dotted lines in the other direction, the overall appearance of the shape will be as follows:

The cross-section looks like a seven-segment display.

There are holes in the shapes. Taking the cross-section of each layer of the shape from left to right, you get:

This reads "unify typos in place rotate right refold" (ignoring the "typos"). Aligning so we can see vertical columns:

yunify
typaos
in6
placye
rotatez
r6ight
refolnd

If you leave the typos in place (that is, "y" is in position 1, "6" is in position 2,... "z" is in position 7) and unify them, you get the string "y66aynz". Pasting the ssections of the original shapes which form these letters together, you get a new shape:

Rotating it right by 90 degrees and adding folding lines like the other shapes makes it look like this:

Re-folding it and reading the letters from its cross-sections spells the following:

ENGAGED is the answer.
