How To Obtain Suitable Technical Drawing?

[balagna]

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.

no, you cannot apply to patent institute with handdrawn drawings. 

in fact,tpe states that you could, but in reality,you can't.

most probably,handdrawn drawings contain shades.

 

here is one sample. I applied to tpe for patent with my handdrawn figures, and the official explanations they sent proves that we could/can not apply with such figures.
