Failed to parse expression in windows

[ebrahim raeyat]

for parsing expression in FreeCAD, i found when i add dot(.) before property in windows os, it sounds an error, but it works in linux, this is my script:

Code: Select all

import Sketcher
import FreeCAD
import Draft
import Part


xcoord = 0
yc = 0
r = 1
text = 'A'

doc = App.newDocument()

sketch = doc.addObject('Sketcher::SketchObject', 'x_sketch')
g4 = sketch.addGeometry(Part.Circle(FreeCAD.Vector(xcoord, yc, 0), FreeCAD.Vector(0, 0, 1), r), False)
t = Draft.makeText(text, FreeCAD.Vector(xcoord, yc, 0))

const_num = sketch.addConstraint(Sketcher.Constraint('DistanceX', -1, 1, g4, 3, xcoord))
sketch.renameConstraint(const_num, f'x_{text}')
sketch.toggleDriving(const_num)
t.setExpression('.Placement.Base.x', f'{sketch.Name}.Constraints.x_{text}')


const_num = sketch.addConstraint(Sketcher.Constraint('DistanceY', -1, 1, g4, 3, yc))
sketch.renameConstraint(const_num, f'y_{text}')
sketch.toggleDriving(const_num)
t.setExpression('Placement.Base.y', f'{sketch.Name}.Constraints.y_{text}')

please note dot (.) before Placement for x constraints and not for y.
