[mueller]

Hi everybody,

im trying to copy a graphic from the book "Introduction to Heat Transfer (Incropera and DeWitt, 4th Edition) Pg. 89"

Im stuggling to get a nice curvy line on top an bottom. Mine is more zick-zack.
I'm also trying to get a asymetric looking cloud.

This is my firt Post in this forum, so i'm very thankful for any critic etc.

Regards,
Jonas

Have you tried the option rounded corners with a suitable value in the styles pencildraw and pencildraw2?

By the way:

The command \bf is deprecated, use \textbf instead.

Instead of applying the command \tiny multiple times, you can also set the font size using the option font.
