I think I was probably the last person to do any major work on the scissors tool, and that was in 1999 to port it to the (then new) tile-based world. The code when I took it on was a "software Vietnam"; a complete mess. I had to read the SIGGRAPH paper it was attempting to implement before I could fix it, and believe me it left my hands much cleaner than I got it! There are two areas where it could do with improvement: - it doesn't handle tile-boundaries (it treats them as edges) - the point editing interface sucks; I merely made the existing one work but it might be interesting to see if it could use the same code from the Path tool (that was always the plan) Austin
