Hi ReeceRD
We appreciate your active participation in the Microsoft Community. Yes, the Microsoft Surface Pro 9 with an Intel i7 processor, 16GB of RAM, and a 512GB SSD should be able to run the full version of AutoCAD and Navisworks programs without any issues. However, it's always recommended to check the system requirements for the specific versions of the software you plan to use to ensure compatibility.
For optimal productivity, utilize an external keyboard, such as the Surface Signature Keyboard, and connect an external mouse when working with CAD software. Additionally, consider attaching an external monitor to create a larger workspace if necessary. Overall, the Surface Pro 9 is a highly capable and portable device, ideal for professionals who require both mobility and performance in their work tasks.
Thanks again for choosing Microsoft. Hope this helps!
Kind regards,
Christopher
