I'm faily new and have looked through the FAQ's but haven't found an answer
yet...
I have ends of two tubes coming together at a 90 degree angle and it looks
just like two tubes coming together. How do I achieve the effect of a corner,
like in a picture frame at the corners, instead of the "overlapping" look of
just two tubes coming together and if you have an answer would you have a short
code showing such?
