I did have some success with hatches when I first tried to use it. I saved the diagram after adding this and posted the file as an attachment. All ok up to this stage.
However, when I went back to the file a couple of days later and opened it, the hatch was not visible. Also, when I go through the process of drawing it in again, it does not show. However, the message above the command field below displays the notification: "Hatch successfully created"!
I tried opening a new file and started with a plain rectangle. I went through the hatch inclusion process with the same result as above. No hatch, but success notification.
What do you suppose is going on? I must have something disabled or enabled that should not be.
One more thing, during the create hatch process, I am unable to preview the hatch, despite clicking on any number of choice options.
