Hi shokan also I guess I should mention that if you want to export a closed curve as a mesh object you must build a surface for it first.

Curves by themselves don't create meshes, only surfaces create meshes when exporting to a mesh format like LWO.

If your curve is planar and closed, you can build a surface by selecting it and running Construct / Planar on it. That will build a trimmed planar surface from a closed planar curve outline.

Otherwise if your curve is not planar then you may need to use some other kinds of surfacing commands such as sweep to build the surfaces - that previous link to some other petal designs I think shows some ways to do that.
