Survey:
Survey points import/export, drafting, polar labeling for road alignments and objects, lifting points to their correspondent elevations written in neighbour TEXT entities, flatten drawing to selected elevation.

                  
DTM:
Building TIN (Triangulated Irregular Network) with filtering points option based on elevations, fitting of breaklines (lines, polylines, 3Dpolylines), filtering triangles based on their Rmax or Lmax of triangle edge, contours generating and quick labeling, basic watershed analysis, refining of triangle network, surface creating/editing/managing

Plan:
PI based alignment, spiral-arc-spiral curve (clothoid defined based on A or L value), sliding vertical spiral-arc-spiral curve (interactivly select R&A values), connect arcs&tangents: arc&arc (reverse/compound curve, arc-spiral-tang-spiral-arc), tangent&arc, fitting arc between two fix elements; 3 center curve (for intersection edge lines), alignment defining/handling, stationing, alignment elements labeling, extracting&tabulating numerical data on curves, road edges construction (with widening in curves automatically applied), vehicles swept paths, alingments import&export, rectification of existing alignments, labeling grades/cross-slopes/pave widths along alignment; station-offset block labels, ...

        
Profile:
Sampling profiles from surfaces, profile view, vertical alignment construction, sliding vertical curve (interactivly select Rv value) labeling: profile alignment, elevation differences, section markers, intersections; superelevation, automatic superelevation design, based on designed speed and horizontal alignment, superelevation editing tools, resulting grades diagram, profile alignment optimisation, road width diagram, diagram of relative elevations for pave edges, station-elev labels - on point spoted in profile or entered station and elev, importing data from external file

                
Cross sections:
Construction of section lines, section views, labeling offsets/elevs/slopes/grades, quantities calculation, summarizing of quantities and report export to Excel spreadsheet, section views with vertical scale, minimum height for resurfacing, station-offset-elev markers, quick sections, reorganizing section views for plotting.

      
Slopes:
Construct slopes on surface, slopes with fixed width and slope, conical slopes, twisted surface, extending/modifying of existing 3D faces, construction of strings, points with slope/grade to certain point, interpolating/extrapolating points,...    

3D model:
Forming and editing templates, forming and editing set of templates, quick template, quick set of templates (template set formed automaticaly, based on alignment, superelevation and pave widths), 3D model construction.

        
Utility:
Quick entity selection filter, slope/grade quering/labeling, XY plane length azimuths, profile and section header titles translation, enhanced layer tools, importing georeferenced TIFF and JPEG format's, summarizing line/arc/polyline lengths and polyline areas, coding points for extracting and tabulating coordinate data.
