RAS Mapper can also display results for multiple cells along a transect. HEC-RAS calls transects of 2D results Profile Lines. To create a results transect Right Click on Features menu and select Create a New Layer | Polyline Layer. Name the Profile Line and press OK (see figure below).
Figure 1. Right Click on the Feature menu to create a Polyline Layer.
This adds the transect to Features and activates the drawing tool. Draw the polyline that you would like to visualize results along. Double click when it is complete. Then right click on the new Feature (Bed Change Transect in the figure below) and select Stop Editing. Click Yes when asked to save.

Now, right clicking on this feature, generates a menu similar to the menu RAS Mapper provides when right clicking a cell or cell face. Users can select a profile plot and animate it with time. A profile will plot a longitudinal transect of the selected result for the displayed time step. As with all of the time series and profile plots in RAS Mapper, press the Table tab to retrieve the numerical results behind this plot.
