# Name:         PS110_bounding_box_to_coordinate_system.py
# Purpose:      Rotates model bounding box in accordance of coordiante system
#                   for the active chunk, bounding box size is kept. The orig.
#                   version of this script (for Phtoscan v.0.9.x) was provided
#                   by the AgiSoft support staff. Updated for version 1.1.x.
#
# Compatibility: Agisoft PhotoScan Professional 1.1.x
