Find and replace columns with others of another sheet

Hello,

I am new here and I would like your help with an issue I am having.

I would like to replace the contents of the columns of one sheet with the those of the columns with the same name in another sheet.

I am uploading a file where there are 2 sheets, "model" and signs". What i want to do is copy the contents of the columns in the "signs" sheet to the columns of the "model" sheet".

Thanks in advance
