In order to enable ESA space programs to assess their compliance with ESA's requirements on space debris mitigation, the DRAMA (Debris Risk Assessment and Mitigation Analysis) software is made available by ESA. The updated DRAMA is composed of six individual software applications, addressing different aspects of debris mitigation (see  for more details). This paper focuses on the new CROC (CROss Section of Complex Bodies) module. It allows the computation of projected cross-sectional areas for user-defined bodies. The computation of the projected cross-section of the complex geometry needs to address two different issues: the cross section of every primitive and the shadowing effects among them, which does not allow to simple sum up every singular contribution.
