Etiquetas de Material en Revit

Descripción

El siguiente código arregla el bug de Revit que dejaba algunas etiquetas de material con un signo de interrogación (?). El problema era conocido pues lleva unos años dándose y la única solución consistía en mover ligeramente la etiqueta antes exportar o imprimir
