   I am using 3DPlot Utility for Surface Generation. In my case, the y upper limit is a function is current x value. Can anyone help solve this problem?

There is an simple form of my problem
0.1 < x < 0.5
0.1 < y < 2*x
(defun z (x y) (list x y (+ x y)))

How should write the code for 3D plot 
(3Dplot z 0.1 0.5 0.01 0.1 '?' 0.01)

Thank you

	If I understand this correctly, you can just modify your Z function so as Y does not go over 2X. E.g. this way: (defun Z (x y) (list x (min y ( 2.0 x)) (+ x (min y (* 2.0 x)))))

	Thanks for your suggestion. your answer solves half of the problem What should write in place of '?' (upper limit of y) in 3Dplot code (3Dplot z 0.1 0.5 0.01 0.1 '?' 0.01) Should I have to replace it by 2(0.5) (ie., 2max of x)? Also in your solution, The values that are greater than 2*x become same points And I think it might change the curvature. Is there an option to not to consider those points Thank you

	It depends on what the max. value should be - probably just 0.5. Due to the meshing algorithm used it is currently not possible to completely skip/omit nodes.
