	In this short article we summarize the FPP package and the tracking code PTC which is crucially based on FPP. PTC is remarkable for its use of beam structures which take into full account the three dimensional structure of a lattice and its potential topological complexities such as those found in colliders and recirculators.

	For the last few years the MAD-X program makes use of the Polymorphic Tracking Code (PTC) to perform calculations related to beam dynamics in the nonlinear regime. This solution has provided an powerful tool with a friendly and comfortable user interface. Its apparent success has generated a demand for further extensions. We present the newest features developed to fulfill in particular the needs of the Compact LInear Collider (CLIC) studies. A traveling wave cavity element has been implemented that enables simulations of accelerating lines. An important new feature is the extension of the matching module to allow fitting of non-linear parameters to any order. Moreover, calculations can be performed with parameter dependence defined in the MAD-X input. In addition the user can access the PTC routines for the placement of a magnet with arbitrary position and orientation. This facilitates the design of non-standard lattices. Lastly, for the three dimensional visualization of lattices, tracked rays in global coordinates and beam envelopes are now available.
