Here’s a quick little nugget that I stumbled across recently – the SUPERHATCH command.
Sometimes you’ll want to “hatch” and area with some unusual pattern, but you don’t have the hatch you’re looking for, nor do you have the time or knowhow to create your own hatch pattern. This is where SUPERHATCH comes in. SUPERHATCH allows you to “hatch” and area using an image, block, xref or wipeout. So if you want a custom hatch, you can create a tessellating block and use that. Ok – you’re not going to be using this command every day, but certainly bear it in mind, because when you do need this functionality, it will be a godsend.
