For those who also want a solution at this moment. I created for me a Script in Blender as Workaround, where I can export an File-Format OBJ from Archicad and import these File into blender with preparing everything to add the Materials. (It's just workng with one single obj)
Manual for using the script
_________________________________________________________
1. Step: Create a folder named "obj" in the same folder as the blender file
2. Step: Drop the obj file into the obj-Folder
3. Step: Copy and paste the Script in blender
4. Step: Click ond the Scene "modell" or create it
5. Run the script

Script
_________________________________________________________
import bpy, os
# Getting Path, which the File is saved
filepath_split = os.path.split(bpy.data.filepath) #list with [path, name]
folder_path = filepath_split[0] + "obj"
# Importing the OBJ-File from a folder in the same Path, which is named "obj"
for file in os.listdir(folder_path):
if file.endswith('.obj'):
obj_path = folder_path + "\\" + file
imported_object = bpy.ops.import_scene.obj(filepath=obj_path)
else:
print("There is no File with the Format OBJ in the folder.")
# Iteration through all Objects in the Collection "Modell" and prepare them for Texture-Mapping
for obj in bpy.data.collections["modell"].all_objects:
# Activating the Object, which will be edited
obj.select_set(True)
bpy.context.view_layer.objects.active = obj
# Creating the right Shade of the Objects
bpy.ops.mesh.customdata_custom_splitnormals_clear()
# Transform and Rotate the Objects correct
bpy.ops.object.transform_apply(location=False, rotation=True, scale=True)
# Selecting the Object in Edit-Mode
bpy.ops.object.mode_set(mode = 'EDIT')
# Seperates the Object and sort it by the Material
bpy.ops.mesh.separate(type='MATERIAL')
# Select the geometry
bpy.ops.mesh.select_all(action='SELECT')
# Call the smart project operator
bpy.ops.uv.smart_project()
# Toggle out of Edit Mode
bpy.ops.object.mode_set(mode='OBJECT')
# Deselect the object
obj.select_set(False)
# Naming the Materials by their names.
for ob in bpy.data.collections["modell"].all_objects:
if ob.active_material:
ob.name = ob.active_material.name
# Creating new Collection an taking the Model inside this Collection.
collection_name = "Object_Import"
collection = bpy.data.collections.new(collection_name)
coll_target = bpy.context.scene.collection.children.link(collection)
collection = bpy.data.collections["modell"]
for obj in collection.all_objects:
bpy.data.collections[collection_name].objects.link(obj)
bpy.data.collections["modell"].objects.unlink(obj)
Still looking?
