Sketchup is in no way a competitor to Solidworks or any CAD tool. Sketchup is a space layout tool that some dedicated individuals have turned into a low fidelity polygon modeling tool (since it’s free) but it in no way is meant for product design.
I use sketchup for space layouts, or quick mockups if I need to bring a 3D interior space into Keyshot since the 3D Warehouse it has is a quick way to get free assets for simple objects like tables, chairs, TV’s, computers, etc - which all work fairly well for low res “Background” props.
