You can use FreeCAD as a base to develop your own application, or simply extend it by creating new modules for it. If FreeCAD is embedded into your own application, you can choose either the GPL or the LGPL license, or any other license that is compatible with LGPL, to allow the use of your work in proprietary software or not. If you are developing a module to be used as an extension, and don't include any of the FreeCAD code in it, then you can choose any license you want. However, if you wish to see your module used as much as possible, it is a good idea to use the same LGPL license as FreeCAD itself, so parts of your code can be more easily reused in other future modules or even in FreeCAD itself.
