Does anyone know how to keep hatching in the background - I use draw order & send to back but next time I open the drawing it is at the front again - I have tried sending everything but hatching to the front - but this does not work either

There is no draworder table yet in Intellicad, meaning it is not stored between sessions. The best you can do is probably something like this (assign to a custom toolbar button):

DRAWORDER;PRO;TYPE;HATCH;;BACK

At least it speeds up the operation a bit
