I think I found something related. for the spline sketching command, I need to define a point() as double. But if that exceeds, it will fail. If it changes to long, it will also fail. But then how could I define point() to fit?
I am trying to cut the spline into different splines, but it does not only increase the load of the program, but also make the coding very hard. Is there a better way that could change the array command point() from double to a larger capability variant?
