This input demonstrates the "drilling-milling" technique available in PLANT to generate marker distribution to fit the complex shapes on cartesian grids. The method rests on PLANT ability to handle virtually "live" mathematical expressions as the arguments of its functions.

All cases of the file are wholly focused on calculation of marker disributions. Therefore, no other actions are supported by input data.

Four different cases, in which the one spherical drill bit is used to get different shapes, are arranged as unsteady problem: at each time moment the new marker distribution is PLANTed calculated and dumped into specified file to be viewed by PHOTON commands supplied

- Drilling diagonal pipe in a cube.

- Drilling the cone in a cube.

- Drilling the spherical chamber in a cube.

- Drilling the pipe junction in a cube.
