Use it to draw a function described by a "equation" [z=F(x)] (Z-X plane) The example done here generate a parabol.
Needs to be defined :
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)
