Arch OBJ
Description
Adicionalmente al exportador estándar de FreeCAD OBJ, el Módulo de Arquitectura dispone de un exportador alternativo que exporta caras coplanares como caras OBJ completas, en lugar de la triangulación de objetos basados en formas, como hace el exportador estándar.
Exporting without GUI
Exporting without the graphical interface is possible from the command line, using the Mesh Workbench exporter only.
In this example, a STEP file is imported, the colors of the Shape are saved, then a mesh is created from it, the colors of the original object are re-applied to the faces of the new mesh, which is then exported to OBJ format. Since this is done with the Mesh Workbench, the result is a triangulated mesh.
import Mesh
import MeshPart
import Import
data = Import.open("example.stp")
shape = data[0][0].Shape
shape_colors = data[0][1]
mesh = MeshPart.meshFromShape(Shape=shape, LinearDeflection=0.1, Segments=True)
face_colors = [(0, 0, 0)] * mesh.CountFacets
for i in range(mesh.countSegments()):
color = shape_colors[i]
segm = mesh.getSegment(i)
for j in segm:
face_colors[j] = color
mesh.write(Filename="new_example.obj", Material=face_colors, Format="obj")
