Använd den för att rita en funktion som beskrivs av en "ekvation" [z=F(x)] (Z-X plan) Exemplet här genererar en parabol. Behöver definieras :
F=variabel som används i funktionen,
X=startvärde på x,
Nb= antal steg,
Z=funktionsuttryck med x
ZZ=funktionsuttryck med xx
# F = variable used in the function,
# X = initial value of x,
# Nb = Number of step,
# Z = function express with x
# ZZ = function express with xx
import FreeCAD, FreeCADGui, Part
import math
F=800
X=-500
Nb=10
Step=1000/Nb
Y=0
for I in range(Nb):
XX=X+Step
Z=X*X/(4*F)
ZZ=XX*XX/(4*F)
if I==0:
print "Le test est vrai !"
nomme=Part.makeLine((X,Y,Z),(XX,Y,ZZ))
WWire=Part.Wire([nomme])
else :
print "Le test est 2 !"
nomme=Part.makeLine((X,Y,Z),(XX,Y,ZZ))
WWire=Part.Wire([WWire,nomme])
X=XX
Part.show(WWire)
