Unlocking an OTK application built for Creo 4.0 F000 requires 3D Drawing TOOLKIT license even though no functions with additional licensing requirements are used. We have linked the following libraries: otk_cpp.lib, otk_no222.lib, protk_dll_NU.lib, ucore.lib, and udata.lib from the VS 2015 version of OTK and TOOLKIT.
Thanks in advance!
