A completely rewritten version in SwiftUI using metal (pretty and fast)

Extended Versions

I have done some custom versions of Rotater for people and for
fun that others may have a use for. These versions are incomplete
to various degrees and are not supported. They are all Mac OS 9 programs.

Odd Versions (PPC):


If you are looking for a quick and dirty DXF to Rotater Converter (19k) look no further (Mac OS 9 application).

Other Conversion and Generation Utilities sent in by people are available here too.

DOS/Windows Version
