Arch OBJ
Description
En plus de l'exportateur standard .OBJ de FreeCAD, l'atelier BIM dispose d'une solution alternative d'exportation qui exporte les faces coplanaires comme des faces OBJ entières, au lieu de trianguler les objets basés sur des formes, comme le fait l'exportateur standard.
Exporter sans GUI
L'exportation sans l'interface graphique est possible à partir de la ligne de commande, en utilisant uniquement l'exportateur de l'atelier Mesh.
Dans cet exemple, un fichier STEP est importé, les couleurs de Shape sont sauvegardées, puis un maillage est généré, les couleurs de l'objet d'origine sont réappliquées sur les faces du nouveau maillage, qui est ensuite exporté au format OBJ. Comme cela est fait avec l'Atelier Mesh, le résultat est un maillage triangulé.
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")
