Sometimes you just need to get an idea of what something is going to look like or how it's going to work before ploughing on too far. Whether relatively small three-dimensional artefacts or large-scale sets & constructions, that might be achieved through a quick but realistic orthogonal or perspective sketch; a photo-realistic rendering; or through a mock-up or scale model.
Quick pen and marker sketches to fully finished colour perspective or isometric visuals.
Full-size 3D mock-ups to scale models.
A way of getting a feel for the final effect without the need to commit to full-blown CAD generation.
