In VIA, alignment and profile are two views of the same road object. All changes that we do in alignment immediately display in the profile and vice versa. This principle is also applied to the cross sections od the road. VIA treats roads and watercourse regulations as 3D objects, not as three separate views that need to be synchronized during the design process.
Cross sections in VIA are managed via cross section constants palette. With it, the body of the road can be set up either through its entire lenght or through shorter sections.
The designer can also edit profiles graphically and add additional custom elements of cross sections. Custom elements can later be populated through other cross sections and displayed in plan and profile view.
The designer can alter course of the polylines that represent the edges of the elements of the road body either in plan or profile view. With this, very detailed changes can be made in the road design, for example we can align the road edge with the existing edges in the real environment, or make specific alterations to the road sholders, etc.
VIA enables the designers to export either the existing or the designed watercourse into HEC-RAS, where calculations can be made.
After the calculations are made in HEC-RAS, the critical water levels can be imported back into VIA, where they can be presented in cross-sections and profile view.
The designers have all the reports at their hands - from stationing data, through elevations, to cuts and fills reports. Special displays also offer the designers the overview of the road wathershed directions and the proposed design elevations display in the plan view.
