I know using such a code for logical conditionals such as:
(-4 . "<OR") (-4 . "OR>")
(-4 . "<AND") (-4 . "AND>")
(-4 . "<XOR") (-4 . "XOR>")
(-4 . "<NOT") (-4 . "NOT>")
etc etc
But recently, I have seen it used in the following way:
(0 . "CIRCLE")
(-4 . "*,=,*")
(assoc 10 dxf_ent)
where "dxf_ent" is the (entget) return for another Circle.
I was just wondering, what is the deal with this "-4" group code? Is there somewhere a list of all the possibilities in which it can be used?
Your input and advice is much appreciated
Cheers
Lee
