Dear Keyur,nHere is the image. I hope this explains a bit better. nAlso, I want to clarify that I am not the only one within my University that has experienced the same issue with ANSYS ICEM 16.2. What I do not understand is why the option suddenly disappeared. It was working fine until one month ago. nI also opened the project file with a text editor and under 'array set file_name'> blocking the option is empty ({}). But if I manually edit it I can load blk file. However, I am still unable to edit the blocks once loaded.nThank you very much for your assistance.nLucan
