Enhance Existing AutoCAD CNC Application

We have an existing CNC application for AutoCAD developed in AutoLISP and compiled as a **.FAS file**.

We would like to make several modifications and add new features to this application. However, the original source code is currently unavailable, and we only have the compiled/protected **.FAS file**.

We are looking for an experienced **AutoLISP / Visual LISP / AutoCAD developer** who can:

* Analyze the existing .FAS application and its functionality.
* Determine whether the existing application can be modified or whether the required functionality should be recreated.
* Implement the requested modifications and new CNC-related features.
* Ensure that the final solution works reliably within AutoCAD.
* Provide the editable source code for the newly developed or modified solution.

Detailed information about the required modifications and the existing workflow will be provided to the selected freelancer.

**Required Skills:** AutoLISP, Visual LISP, AutoCAD API, CNC/CAM workflows, and experience with legacy AutoCAD applications.
