Spline problem

[Anonymous]

I am using the version AutoCad 2014.

I have a problem with the spline. when I drawing spline, I choose a endpoint, then the spline goes to "infinity". (see picture).

I do not know what to do because the problem is only in that file.

Thanks in advance

Do you have a running osnap on?
Is your UCS rotated? is PLAN set to World?
is the problem present in ALL files or just this one?

You might check your OSNAPZ setting.  It may be snapping to a Z point off in space.
