I was reading this research paper titled Sub-modeling Finite Element Analysis of 3D Printed Structures. In this, firstly, the author is trying to create a sketch for Engineering analysis using the 3D printing path coordinates and integrating it to a CAD software like Autodesk Inventor.
By analyzing the corresponding G-code for the desired structure, important information can be extracted, such as the coordinated of the 3D printing path, key points, paths of printing and non-printing paths.
The coordinate of the 3D printing path can then be imported into CAD software to obtain the corresponding sketch and consequently a solid body for each layer. Most of commercial CAD software packages are capable of this task. For this Purpose we have chosen Autodesk Inventor.

Can anyone help me out with how this can be done?
