Hi Gary,
Along with many others, I still use LazyCam and it’s predecessor Mac1Filter.exe. albeit only occasionally. In my case it is mainly for handling HPGL files and within their limitations they are both great products and well worth learning to use.
For .dxf and similar work these products have, unfortunately, been technically overtaken by many, more advanced, softwares (for example the Vectric range) mainly because of the additional features, speed and ease of use.
There will always be new and better software coming along but who is to say that the old stuff is not still good ? (When Mach Rev4 arrives many will change camp but if Mach3 does the job...)
Tweakie.
