Due to complex and large geometry and to avoid a lot of partitioning for generating the mesh, If I make a solid part into the shell part by using solid to shell converter in Abaqus. Then in the material property assign section: what should I put in the thickness of the shell which is already provided during the 3d part drawing?  

By converting the 3D solid to shell part is it become 2D conventional shell or 3D continuum shell part?

Thanks in advance
