Pendean,
It seems Autodesk doesn’t embed time lock in AutoCAD. Once AutoCAD downloaded to my laptop, it is active even after my access to Autodesk has expired. Of course, my AutoCAD doesn’t get updates.
By scrapping my 2D drawing, I’d rather use Solidworks for 3D. I learned one class of Solidworks before dropping out school which left me a feeling that it is designed in an “intuitive way” to use, similarly to iOS, In comparison, AutoCAD is useable which is designed in a “mediocre way” just like Windows. Yet, AutoCAD has monopolized 2D market like Windows’ monopoly. I tried FreeCAD, an open source software and found out its website is poorly managed, worse than Autodesk’s. It seems lack of fund is common problem of open source apps. Without competing, why would Autodesk board hold users dear? Autodesk website bugs will NOT get fixed and the company will NOT pay attention to its website users’ feedback, which is sad.
