What if you guys can somehow mark the start of the first node which would the verify what direction the string is set up for. You could select the model and the first node would be highlighted (lets say red) and when done adjusting it, the first node marking goes away until you click on the string again I can see how that would help in most models at times Then maybe put ( model string orientation) or something like that above - top left, top right, botton left ect .so user would know that it can be used for all models. I thought it was just used on martixes and trees , and didnt think to use if for other models. Just a couple of ideas not knowing how hard it would be to incorporate into the program or if its even possible. Then again if it is even feasable. I got to a point that I took on too much last year and things started to get confusing so if there was a basic marking it could have saved a whole lot of headaches.
