Hi All.
This lisp can to draw ditch from polyline and hatch it inside with option to change hatch properties:

as usual for me it working properly, but... "dirty".
Lisp have at least two problems
1. User need to select hatch inside closed polyline in order to change it properties, but this is (entlast) entity and no necessary to select it - just change
2. Inspide of the fact this lisp can work with splines:
(setq ent
(car (AT:
Entsel nil "\nSelect curve: " '
("L" (0 .
"ARC,LINE,SPLINE,LWPOLYLINE")) nil)))
in this case lisp start to work not properly (return error on stage of creating closed polyline)
I can fix this error if I change this string..
to this:
but in this case user need to select spline twice..
Is it possible to make some improvements in this combined routine?
Any help will be very appreciated
