How do you align two 3D parts without adjusting their position manually?

[indiancad]

When assembling a 3D model, positioning one component accurately against another can be difficult, especially when both parts are at different angles.

Instead of repeatedly using MOVE and ROTATE3D, 3DALIGN can help. By selecting matching points on both objects, you can position and orient one part accurately.

I find this useful when assembling mechanical components or placing parts into an existing model.

Do you use 3DALIGN for positioning 3D components, or do you prefer to adjust their position manually?
