CNC files
In addition to detail shop drawings and specifications, AnsvarCAD supports CNC machine file generation. Users can generate both BTL and BVN machine files. BTL is a free standard, which means that it is not tied to any specific machine manufacturer and thus enjoys wider use. BTL is read, for example, by Weinmann and other machines which generally convert BTL files into their proprietary format (WUP and other formats). BVN, on the other hand, is designed for Hundegger machines and is read directly.
Machine file generation is extremely easy, yet highly flexible, allowing the user to define the data saved in the machine file.
