1. A modular tooling configured to manufacture multi-spar torsion boxes of different web heights, the modular tooling comprising:
a mandrel module including a hollow beam geometry which comprises a first base, a second base opposite to the first base, and two walls extending between said first base and said second base, and
at least one spacer module configured to couple with the mandrel module, wherein the at least one spacer module is selected from a plurality of spacer modules each having a common width and a different height;
wherein a web height of a multi-spar torsion box being formed by a stack of the mandrel and the at least one spacer module is defined by the stack, and
wherein the stack and the mandrel module each have a width substantially the same as the common width of each of the at least one spacer module.
