Hi there, we have a project written in C++ that build a file . arx. This .arx load on Autocad 2016 return error because header and include was for Autocad 2002.
What we need is a simple project that can buil an .arx with Autocad 2016, I will give a couple of routine written in C++ to copy inside a class. Some building test and support after release.
