These Open C programs are routines that follow the Open C guidelines and rules. See the Open C Help. The functions included in the Knowledge Fusion Open C API are documented here. There are two different user function APIs available. The UF_KF interface allows you to create user function programs that can call Unigraphics NX Knowledge Fusion functions from your user function program. See Calling UG/Open Knowledge Fusion from a UF for an explanation of this API. The UF_KF interface allows you to define your own Fusion function that will call your user function from UG/Knowledge Fusion when it is invoked, in order to execute your User function routine. See Calling UFs from UG/Knowledge Fusion for an explanation of this API. These APIs are known collectively as the UG/KF UG/Open API.
