I needed to build a harness under a tight deadline with constantly evolving modifications and was getting overwhelmed keeping track of the changes across the TO_FROM table and diagrams. I initially tried wireviz, and it was great, but adding images and describing the harness in Yaml was kind of a mind-bender for me. I also needed some general features that were either hard to find documentation on or were very hacky (which was okay for the time being). Some of these were lengths per wire and an easier distribution method for the BOM. I spent some time trying to think of how to make this process easier for myself and ultimately built Wirely. It's a ground-up development that integrates various software to help in visualizing and generating simple to moderate complexity wiring harnesses. It uses WebGL for fast rendering, graphviz for graph generation, as well as other libraries for the different file format outputs. I've been using it to create as much stuff as I can, and I've gotten lots of feedback about making it better. I'd like even more people to try it out and provide feedback. The online editor is free (with limitations on how many iterations until a cooldown period). Let me know what you think!
