Dear Maxim,

Many thanks for your reply, I am grateful for the helpful solution and feedback. If possible, I would like to ask if how exactly the MESHSMOOTH command works, as I have already read this through Autodesk forum and still didn't work correctly. The attached images are shots taken while using the MESHSMOOTH. Hence, after clicking create, I guess it didn't get modified as the one you've sent me the faces are seen. 

Apologies for asking again about this situation, though I am new to 3dACAD.

Regards,

R
