# Cannot import name 'common_utilities'

I'm trying to enable my polystrips addon but I receive this error every time I try to check the enable addon box.

• Looks like you are having the same type of problem as I answered here – David Feb 14 '16 at 0:11
• I renamed my folder common_utilities and I'm still getting the same error – Sam 3D Feb 14 '16 at 0:34
• have you posted on the support page for the product you are using? – patmo141 Feb 14 '16 at 14:30

It appears you need to grab the code from here https://github.com/CGCookie/retopology-lib and put the source files (ie __init__.py, common_utilities.py, common_drawing.py, common_classes.py) into the empty retopology-polystrips-master/lib folder
