Horizontal alignment
The IPs of the alignment: the first row is the start point, the last the end point. Radius 0 means no curve at that IP, Ls 0 a simple circular curve. IRC radius and Ls sets the minimum radius and transition for the design speed.
The plan and the curve table follow every change; Draw plan puts the plan with chainage ticks and curve tables on the drawing, Curve report writes the Excel table. IPs can come from a polyline (AutoCAD) or a CSV file (Name, Easting, Northing, Radius, Ls).
A project can keep several alignments; the one marked ★ is the alignment of the sections (coordinates, superelevation, LandXML).
Commands
CXHALIGNHorizontal alignment and plan…
IPs with spiral–circular–spiral curves, IRC radius and transition checks, curve table and Excel curve report, plan with chainage ticks.
CXCURVESSuperelevation and widening on curves…
How the templates change on the curves of the alignment: superelevation and IRC extra widening for roads, cant and formation widening for railways – per curve worked out from the speed or typed, with the superelevation diagram. The marked template elements turn and widen when the templates are applied.
CXTINSECCross sections from survey points…
Sample ground levels from a TIN of survey points at stations and offsets along the alignment.
CXPLANCSDraw section lines on the plan
Draw the section lines (and levels) of the project on the alignment plan.
