hello,

i need to make a fairly simple mask, and i would like to use autocad =
since i know it fairly well...

i have found a good, fairly affordable (linkedit) dxf -> cif,gds =
converter, but my question is this: do u draw a closed polyline (ie a =
rectangle) or a pline w/ some nonzero width (ie 5 units =3D 5um). if i =
draw rectangles, the resulting cif file is composed of polygon (P) =
commands followed by vertices. if i draw wide lines, the resulting cif =
file is composed of wire (W) commands.

is one better than the other...or does it really matter? or do you do =
something completely different.

any tips appreciated,

dan

i have found a good, fairly affordable (linkedit) = dxf ->=20 cif,gds converter, but my question is this: do u draw a closed polyline = (ie a=20 rectangle) or a pline w/ some nonzero width (ie 5 units =3D 5um). if i = draw=20 rectangles, the resulting cif file is composed of polygon (P) commands = followed=20 by vertices. if i draw wide lines, the resulting cif file is composed of = wire=20 (W) commands.
