My original image drawing 2D

I find it strange to post my Autocad image a few hours backward, the image I post is pure my original image.
Why in my upvote at latitude. Okay thank you to the steemit maybe it's the provision of apkilasi or sofwer steemit itself i understand..

This may be from the next post images that I have saved to PDF, maybe from the founder of steemit more understanding, thanks to the founder sofwer steemit so I understand more and more spirit in the work.

There are any pictures I post this purely original I made:
