I'm trying to help my friend who's getting some metal pieces cut so that he can bend the metal easily. The files he received have the cut lines along the outer perimeters as they should be, but the internal "bend lines" extend all the way to the outer perimeters, which would result in every section being cut into individual pieces on the cutting machine. So I'm going through and shortening the "bend lines" by 7mm along all the edges, so that there will be solid metal there in those 7mm gaps that can be easily bent. In the attached photo, I have already shorted the bend lines on the right side of the object, and the bend lines on the left side of the object are the unedited lines that I'm going through and shortening.
Does anybody know of a Command Line Tool where I can select all the lines on a given layer (the red or blue layers in the photo for instance) and shorten all of them at once from both ends of the line toward the center?
Other questions: Are there any reputable repositories where I might try and browse for such a Command Line Tool? Is there a similar tool that I might be able to easily adapt for these purposes?
Thank you very much, any help is greatly appreciated!
