Thank you for replay.
However, the issue is that I already build a 3D system model. I need to extend what I have to add new trait to it which is path plan. This path plan done in 2D points and its coming from default 2D packages. While I already have a built in 3D points.
Both 3D and 2D programs have different GUI. I need to but the 2D program to a 3D one and run it as a 3D program in one GUI.
