Hello, I;m having a problem and this is due tomorrow. Everytime i save it to a pdf, the hatch disappears and doesn't show in the pdf file. The weird part is that one of the hatches saves, while the other doest. Link to images provided below. What should i do? Please help, it'd be hugely appreciated.

save to PDF? Try using PLOT command instead, find out which PDF driver you are using and what 'hide' settings may be set among others.
