Each link carries a width, a slope in percent, a depth, a colour and a cut flag. A link with Cut = False is drawn at its literal width whatever the terrain does -- a carriageway, kerb, berm or wall. A link with Cut = True searches outward until it crosses the ground, up to the template's MaxW.
▪
The supplied presets are Link, CutBat, FillBat, Berm, Wall, DitchIn, DitchOut and Split. A Split link is a branch point: it follows its CutBat sub-links where the ground is above formation and its FillBat sub-links where it is below, so one definition covers a corridor that alternates between cut and fill.
▪
Mirror reuses the right-hand link list on the left. MaxW is how far a batter may search for the ground before giving up. TM, the template margin, is how far past each batter point the ground profile is drawn and trimmed.
▪
A template can be flagged as a structure. Bridge reports no cut or fill at all, since the deck spans the ground, and records a deck thickness separately. Tunnel computes the excavated area from the formation width and a clearance height, and reports it all as Cut.
▪
A full set of templates saves to, loads from and merges from a .ltl file in the native MX format, so a library built for one project can be reused on the next.
▪
The paclet ships the example template library used by the worked examples -- Type 1, Type 2, tunnel, Dual 2 lane motorway, Single carriageway and Bridge. Get its path with PacletObject["MalcolmWoodruff/LineTerra"]["AssetLocation", "TemplateLibrary"], then open it with Load Library in the Templates panel.
