if anyone can help me?
I try to draw surface by a rectangle, but it comes as wireframe only. And when I make extrude, it make as walls as shown.
Plane command helps you create rectangular surface.
If you’re using ExtrudeCrv command you can activate Solid from commandLine options.
Not sure what you are doing, or what you want.
For a rectangular surface try, _Plane.
To extrude your line rectangle try, _ExtrudeCrv
Extruding your rectangle with the Gumball dot will give the open structure you’re showing.
You drew a rectangular curve, not a surface. Rhino has both curves (which if straight are lines) and surfaces. They are different types of objects.
Excellent 
Done, Thanks
