Thanks for the reply, I imagined there was not the proper command to execute this, and also I am aware of the difference and the cost, but I was wondering if the problem could be solved by other ways, however I encountered another problem on this object and I am attaching the file below, the problem is related to the thickness command and I was unable to give a thickness, maybe I made some mistakes if you can look at this file. 
Tomorrow I will check if there are any errors that I have not found for now.
Thanks

edit: added image of the solid with Blender
and this is the Nurbs patches imported in Blender via special build that can import the 3dm nurbs as patches and rebuilt as mesh and added thickness and imported into Moi3D again as SubD and I get a solid in this way-
