Hi,
Anyone can rectify the error on this lisp routine . I tried my level. not resolved.
Program For.
AutoLISP routine built for AutoCAD Civil 3D that:
• asks you to pick an Alignment and TIN Surface,
• samples every “input” m along the alignment,
• builds a perpendicular Sample Line (you choose left/right width),
• extracts every surface intersection point along that perpendicular (Civil 3D’s section engine gives you the exact TIN intersections),
• and writes Easting, Northing, Elevation, Station, Offset (signed) to a CSV.
Best regards,
PCKU
