Description

Cette macro crée un wire (ou points) avec les coordonnées XYZ extraites d'un fichier. Les coordonnées X Y Z sont séparées par un espace.

Utilisation

Le fichier doit avoir les coordonnées X Y Z au ASCII sans entête.

Script

Macro_WireXYZ.FCMacro

# -*- coding: utf-8 -*-
# created a wire with coordinate x y z separated (in the file)
#EX:
#0 0 0
#10 10 10
#15 20 25
#. . . .

from __future__ import unicode_literals
from FreeCAD import Base
import Draft, Part

fichier = "C:\yourPath\cloud.asc"                          # path and name of file.txt

file = open(fichier, "r")                                  # open the file read
wire = []

for ligne in file:
    coordinates = ligne.split()
    X,Y,Z = coordinates                                     # separate the coordinates
#    Draft.makePoint(float(X),float(Y),float(Z))            # create points (uncomment for use)
    print X," ",Y," ",Z
    wire.append(FreeCAD.Vector(float(X),float(Y),float(Z))) # append the coordinates

file.close()
Draft.makeWire(wire,closed=False,face=False,support=None)   # create the wire open
#Draft.makeWire(wire,closed=True,face=False,support=None)   # create the wire closed (uncomment for use)

... Modify your path and name of file, save and load the macro and run.

fichier = "C:\yourPath\cloud.asc"                          # path and name of file.txt

If you want a close wire modify this line (closed=False):

Draft.makeWire(wire,closed=False,face=False,support=None)   # create the wire open


and replace with (closed=True):

Draft.makeWire(wire,closed=True,face=False,support=None)   # create the wire closed

same for the face, False or True (face=True).
