Hello,

Has anyone successfully designed photomasks on a Macintosh? I know I
need to make either .dxf or GDS files. For GDS, the only option is
dw-2000 (and the lite version), which I'm looking into, but is extremely
expensive and probably overkill for the simple MEMS work I'll be doing.
The most popular option, it seems, for those who don't want to buy a
program like dw-2000 is AutoCAD, but there is no Mac version of this.

There are several of Macintosh CAD programs, and even something like
Canvas claims it can save .dxf files. But I don't really believe
publisher's claims of AutoCAD compatibility, especially for .dxf -> GDS
or .dxf -> pattern generator machine code stuff.

So what software has anyone successfully used to design photomasks on a
Macintosh?
