The ability to create your own models is very useful when it comes down to creating my projects at work or school! I can make all of my plans in one place instead of having to go between multiple programs that aren't designed with each other's strengths in mind! Some parts are difficult to navigate without an understanding of how they function which makes them easy to use sometimes but not others.
It would be helpful if tutorials explained every part so users could understand what goes where once there are no instructions given out. In addition to being able to design 3D structures/designs like building spaces or rooms for schools this has helped me improve communication skills within our team as well since most people do not know how CAD works outside their usual job responsibilities (which isn't much).
