A:Answer I would think you are asking about the software running properly on this computer, because for learning technical drawing you don't even need a computer.
So, if your question is about running AUTOCAD or REVIT on this computer, be aware of the need of another external or internal hard drive, and try also to add extra 8GB of RAM, to run the software smoothly.
This means that you need at least an extra $200, to make it technical drawing friendly.
You are welcome.
