form tools and stamps

other than to just show the after math of using a form toolwhat is the actual point to make a form tool and then to place itinto the 3d model?

it doesnt effect my blank size because i cannot unbend them.
the formed dimensions are basically for reference anyways so notlike i couldnt just make some sketch lines in the drawing itself torepresent after punch

im just kinda new to stamping and making shapes in my sheet metalpart and now that i know HOW to do it im wondering why i would wantto do it especially because the company i work for rarely stampsanything and if we do its from a stamp supplied to us and webasically just locate it on our sheetmetal part and thats it

just wondering on some real world solidwork reasoning and usage
