Most of the mod-PATH3DU menu commands are found by right-clicking on the mod-PATH3DU item in the Project Explorer. There is no mod-PATH3DU menu in the main menu bar.

New mod-PATH3DU... 
This command is found by right-clicking on a ugrid. It results in the creation of a new mod-PATH3DU simulation. Multiple simulations can exist at the same time.
Run mod-PATH3DU... 
Launches the mod-PATH3DU executable with the selected model as input. The project has to have been saved previously so that the mod-PATH3DU input files are ready to run.
Check Simulation... 
Opens the mod-PATH3DU Model Checker which can be used to detect obvious errors in the model setup.
Options... 
Opens the mod-PATH3DU Options dialog which lists the options available for modifying the model.
Porosity... 
Opens the array editor dialog that allows specifying porosity for every cell in the model. This porosity array is the same as the one used by MODPATH and is accessible from the MODPATH menus as well as from the MODFLOW Global Options/Basic Package dialog.
Tracking Algorithm... 
mod-PATH3DU allows specifying the tracking algorithm to be used on a cell-by-cell basis. This data is saved as an array in the MPBAS file. This command allows editing this array. A value of 1 indicates the Pollock Method, a value of 2 indicates the SSP&A method, and a value of 3 indicates the Waterloo method (recommended).
Create Particles At Wells... 
Creates particles in cells that contain MODFLOW well boundary conditions. A circular ring of particles is created around the center of the cell.
Create Particles from UGrid... 
Creates particles from the points or cells of a user specified UGrid.
View Pathline Report... 
Opens a dialog showing a spreadsheet containing information on all pathlines in the selected simulation.
Export... 
Allows saving model data in various formats: the native model files, the pathlines to a line shapefile, the pathline points to a point shapefile, the capture zone polygons to a polygon shapefile, the pathline data to a tab delimited file.
