I would like to apply to patent institutes for patents.
in fact, I had applied once offically but I clearly learned that technical drawing was required.
but how? presumably wkikipedia states that I could do that by solid 2d edge draft,but I could not download from anywhere (because wikipedia also says that it was easy and free)
I need help.
thanks in advance.
