It's been a while since I tried OpenCutList, so I could be wrong. My recollection is that it, like several other cutlist extensions I've tried, requires you to add some extra attributes to each object, for example to tell it which way is the long axis of each board. Steve R's CutList needs no extra attributes or setup and I like that simplicity. It makes the assumption that the largest dimension is length, next largest is width, and smallest is thickness. That isn't always right but I don't find that to be a problem for my work. I prefer to organize the actual cutting of the boards based on grain, coloration, and flaws in the boards anyway, which requires me to think about which way they go.

Thanks TIG, I will definitely have a look again. To be honest this is turning into a bit of a headache, all I'm trying to achieve is turning one thing a different colour and back, just thought if I gave it a go it would save me time in the long run. I'll give this another go in a day or so but for now I'm just going to have to do things the old fashioned way and make two of everything in different colours. This DC stuff has gotten me well and truly beaten for now. Thank you so much for commenting TIG, I really appreciate the help. Kind regards mitch7780
