Question: Plotting a surface from three data lists - how?

I'd like to plot a surface from three lists in the following way:

For each item in the list X we have a specific curve "plotted" in the plane Y vs Z.

In other terms, we have something like that: each X[i] will be related to two lists, say, Z[1], Z[2], Z[3] and Y[1], Y[2], Y[3], X[i+1] will be related to Z[4],Z[5],Z[6], and Y[4],Y[5],Y[6] and so on...

A very 'thin' surface following this would be, as a example:

X=[1,2]

Y=[[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29], [2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30]]

Z=[[20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49], [21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50]]

I am looking for some tutorial showing something similar but without any success. Please, any kind of help certainly will be absolutely very appreciated. Thanks in advance! Best regards,
