Opzioni
Principio di funzionamento :
pointsDirection = lineSelected.Shape.discretize(Number=500) # discretize the path line first selection
la perpendicolarità è calcolata tra 2 punti modificando :
v=pointsDirection[0].sub(pointsDirection[1]) # perpendicular of first > second point
2:
v=pointsDirection[-1].sub(pointsDirection[-2]) # perpendicular of last > before last point
pl.Base = pointsDirection[-1] # position base last point
3:
v=pointsDirection[100].sub(pointsDirection[101]) # perpendicular of point 100 > point 101
pl.Base = pointsDirection[100] # position base point 100
4:
v=pointsDirection[0].sub(pointsDirection[-1]) # perpendicular of first point > last point
pl.Base = pointsDirection[0] # position base first point
per discretizzare gli altri parametri
# Discretizes the edge and returns a list of points.
# Forum thread: https://forum.freecad.org/viewtopic.php?f=12&t=16336#p129468
# The function accepts keywords as argument:
# discretize(Number=n) => gives a list of 'n' equidistant points
# discretize(QuasiNumber=n) => gives a list of 'n' quasi equidistant points (is faster than the method above)
# discretize(Distance=d) => gives a list of equidistant points with distance 'd'
# discretize(Deflection=d) => gives a list of points with a maximum deflection 'd' to the edge
# discretize(QuasiDeflection=d) => gives a list of points with a maximum deflection 'd' to the edge (faster)
# discretize(Angular=a,Curvature=c,[Minimum=m]) => gives a list of points with an angular deflection of 'a'
# and a curvature deflection of 'c'. Optionally a minimum number of points
# can be set which by default is set to 2.
