This module provides the user with a simple python API to realize
|
|
various sketches from the GEOM text user interface.
|
|
|
|
Example::
|
|
|
|
from salome.geom.sketcher import Sketcher
|
|
|
|
# Create the sketch
|
|
mysketcher = Sketcher()
|
|
mysketcher.startAtPoint(0,0)
|
|
mysketcher.translateToPoint(100,0)
|
|
mysketcher.translateWithAngleAndLength(30,100)
|
|
mysketcher.intersectYWithAngle(15,100)
|
|
mysketcher.close()
|
|
|
|
# Get the geom object
|
|
wire = mysketcher.getGeomWire()
|
|
|
|
# Put it in the study
|
|
from salome.geom import geomBuilder
|
|
geompy = geomBuilder.New(salome.myStudy)
|
|
geompy.addToStudy( wire, 'mysketch' )
|
|
|
|
Additionnal examples can be found as unit tests in the source code.
