The placement of objects in any 3D scene requires a certain amount of attention to detail to ensure models don’t overlap when they shouldn’t. This is especially the case for product or small-scale visuals, where it would be immediately obvious if there was an issue.
In most 3D software packages you have to rely on your eye or, more helpfully, the built-in snapping tools to ensure accurate contact but nothing more. Snapping tools are an absolutely essential part of any modelling workflow, but they can be a bit cumbersome when you need to adjust the properties and make sure you’re snapping to the right parts.
