Description
Cette macro crée un triangle isocèle en donnant comme argument , l'angle de tête et la hauteur du triangle. La tête du triangle est positionnée aux coordonnées XYZ 0,0,0.
Utilisation
Copiez la macro Triangle AH complète dans la console Python de FreeCAD et tapez :
triangleAH(angle=90, height=10) # or triangleAH(90, 10) # or triangleAH(45, hypo=10) # or triangleAH(90, base=10)
