I am working on a figure which has a mathematical shape.

I coded on MatLab the points in the xyz cordinate.

I saved the file as .xyz format to be able to open it on SolidWorks as point cloud.

I successfuly open the file but I want to make it solid. I make the surface first by using the option Mesh Prep Wizard then I tried using the Surface Wizard option (Automatic and Guided) but neather of them worked.

With the Automatic it develops some kind of a mesh but it looses acuracy on the edges and the surface.

With the Guided I tried with each reference plane individualy but it didn' work. 

I also tried using the Curve Wizard but the curves that it develop at the edges of the part are not that accurate with the edges.

I even try using the Knit option but it needs more than one surface to use as a reference, but it doesn't recognize my mesh as a single surface nither as a combination of surfaces.

I think there should be a easier way to develop a solid structure having a enclosed figure.
