It happened to you also: you downloaded some 3d models from other parts – for example taps, furniture and others – and your collection became full of a thousands of objects – for a simple one you needed; multiple objects and parts difficult to select each time, and then move or rotate…
What to do? How to simplify the model?
Very simple. Use join.
- select all the pieces (from the model, or from the collection panel)
- go to the menu of the viewport
- Object
- Join
Done!
The result is a final unified object. You still can apply different textures to different meshes but of course it is useful only when you don’t need to modify the geometry anymore.
