Are these lisp routines from ldt incorporated into C3D someplace or were they left behind with the abandonment of ldt?
I'd wrather not use feature lines or contours, we work with lines and arcs for non-corridor/offsite grading.
I just want to offset my lines and arcs so that they offset by horizontal and vertical based on a slope and a grade, like ldt used to do so simply.
thanks for any help on this!
