No. SVOffice is the platform which manages how all the software modules communicate to each other. Like in Microsoft Office - you can purchase any program (SVFlux, SVSlope, etc.) by itself or in combination with other programs and they all have a common interface.
The SVOffice interface has been designed to simplify learning & speed model setup for the user. The menus and layouts in each module have been designed so that similar commands will be found in the same menu in each software module.
All menus have been laid out in a left to right format. When you start setting up your model you will start with menus on the left, and as you progress with your modelling you will move through the menus from left to right.
