Description

This macro creates a wire (or points) with the coordinates extracted from a file. The coordinates X Y Z are separated by a space.

Usage

The file must have three coordinates X Y Z in ascii format without header

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

## path for Windows    : C:\yourPath\cloud.asc (create one error in Python (cause, the "\" is a command syntax in Python)
## replace "\" by "/"  result : C:/yourPath/cloud.asc 
## or replace the "\" by "\\" result : C:\\yourPath\\cloud.asc

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).
