Answer : Both programs have their pros and cons, but for most people, SketchUp is much easier to learn and use.
SketchUp is a 3D drawing program that's great for creating simple designs or rough sketches. It's very easy to use and can be learned in just a few hours. However, it's not as powerful as Revit and doesn't have all the features of a professional CAD program.
Revit is more complex than SketchUp but offers greater flexibility and can be used to create more detailed designs. It's also widely used in the construction industry, so if you're planning to work as an architect or engineer, then you'll need to learn Revit.
