### 5.1.4. Thickness Correction

The thickness correction option of the internal draping feature changes the thickness of a draped ply when it is sheared. The draping mesh is laid down on top of the finite element mesh and its size is independent of the finite element mesh. Thickness correction algorithm is based on conservation of volume per draping element. For that purpose, the ratio of the area of the distorted draping element to its plane reference is computed and the thickness of the analysis plies being considered is corrected accordingly.
