Hello everybody,
as most of you know, a drawing file has tables containing linetypes, etc. so there is no need to have acad.lin or acadiso.lin to get definition of loaded linetypes.
I find out this is also correct for hatch patterns, i.e. if you use a hatch pattern to hatch a boundary, even after deleting the HATCH object, definition of the pattern remains in the drawing.
My questions are:
1- How is it possible to get these hatch pattern definitions? (for linetypes AutoLISP functions (tblobjname), (tblnext), etc. work well, but for patterns not.)
2- How can one purge them out of drawing?
Thanks in advance
