Remove the point which is in a user define tolerance for curve which have multi
I'm not sure I understand completely, but PLDIET.lsp with its PLD command may do what you want. Available >here<. You can tell it both how far apart and at what maximum angle of bend you want vertices removed.

The quickest suggestion I can make would be to draw a Polyline using that point list first, and then put it on a diet with PLD.
The routine could be adjusted to work on a point list instead of on a drawn Polyline, but it would take me a while to get re-acquainted with how it works, and make the adjustments.
But it would be helpful if you can post an image showing exactly what you mean by "remove points within user define tolerance for angle" -- I have an idea of what I think it means, but I may be wrong.
