ACP/Pre is very useful for layups on complex 3D shapes.

Structures bonded together from flat or cylindrical composite sheets and ribs don’t need ACP/Pre. Look up Defining and Applying a Layered Section in the Mechanical Application chapter of the ANSYS Help system. Insert a Layered Section into the Geometry branch of the Outline. In Engineering Data, add the Composite materials such as the Unidirectional Carbon Fiber Prepreg. In the Worksheet for the Layered Section, you can define the layup of plies. Each ply has a material, thickness and angle. Create as many plies as needed: 4, 8, 16 etc. Now you can select as many sheet body faces as you want for this Layered Section. You have a short list of unique layups. Create a Layered Section for each layup and give it a meaningful name. Select the faces that apply to each Layered Section. In this way, the correct composite material properties will be assigned to each sheet body of your structure.
