Программирование

The Truss tool can be used in macros and from the Python console by using the following function:

Truss = makeFence([baseobj])

Пример:

import FreeCAD
import Draft
import Arch

p1 = FreeCAD.Vector(0,0,0)
p2 = FreeCAD.Vector(2000,0,0)
baseline = Draft.makeLine(p1,p2)
truss = Arch.makeTruss(baseline)
truss.HeightStart = 200
truss.HeightEnd = 400
# adjust other needed properties
