BPY plus – a set of modules to extend the Blender Python API.

BPY plus is an open-source project based on Blender API and extending it with several features and making it easier to use some of “bpy” functions.

You can use BPY plus in your add-ons and scripts in any way for free.

At present it is small, but in the future, it can be extended with more modules.

The “bpy_plus” package must be placed in the same directory as the project in which it will be used. Copy “bpy_plus” to your project directory. Now you can import “bpy_plus” modules as usual

from bpy_plus import *

from bpy_plus.bounding import Bounding

empty = bpy.data.objects.new(name='empty', object_data=None)
empty.empty_display_type = 'SPHERE'
