Thanks for the unexpected and random complement.
I am still learning how to use Newton myself. One day I will be great at building, and another day I can't make bupkis. This is why I prefer the much more challenging and time consuming method of "hand building".
Keep at it, look over your work carefully, and you will be very satisfied with your work. Just remember, you need to spend a lot of time with a track to make sure it turns out the way you want it. Never settle for the easy way out!
