Arch: File OBJ

Descrizione
Oltre all'esportatore OBJ standard di FreeCAD, il Modulo Architettura dispone di un esportatore alternativo che esporta le facce complanari come facce OBJ intere, invece di triangolazioni eseguite su oggetti costruiti su forme di base, come fa l'esportatore standard.
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")
