Cleaning up a logo

[Bigrhamr]

I have been trying to get my logo to burn better. It seems to have alot of extra line which causes the laser to go over an area too much. My question, is there a way in LB to ID and delete these hidden lines? Or am I just stuck zooming way in and cutting them out?

Select shapes
Ctrl + D ( Duplicate) and move aside, it´s a copy in case something goes wrong
Ctrl + U (Ungroup)
Ctrl + B (Break Apart)
Alt + D (Delete/check for duplicates)
Delete if some
Alt + J (Auto-join selected shapes)
