Position objects along a curve

User Guide > General > Basics > Transforming objects > Align and snap >

You can reposition a selection of objects so they are spaced evenly along a curve. For example, you can create a line of fence posts that meanders along a winding road.

To position a selection of objects along a curve

Draw a curve in the scene to indicate the path along which you want the objects to be positioned. (Alternately you can duplicate or use an existing curve in the scene).
Select the objects you want to have evenly positioned as well as the path curve and then select Modify > Snap Align Objects > Position Along Curve.
The selected objects are repositioned so they are evenly spaced along the curve.
