This MCG creates Spline Grid/XGrid pattern that is a seamless cylinder. You are welcome to use my free XGrid which is much harder to do...it can be found here:

However, this MCG saves you doing manual welding after you've bent it into a cylinder. This is easy to do if you can study my XGrid graph...I encourage you to do it yourself.
