Is there any training needed to operate nanoCAD?

nanoCAD is a CAD application for 2D and 3D design and drafting. The software has AutoCAD-like interface, known command prompt and directly supports the format DWG. nanoCAD is used for the creating and editing of vector primitives (graphic elements) and more complex objects (blocks, dimensions and etc.).
So it is very familiar to the new user to evaluate the application and no training is required to operate nanoCAD.
