5. Select the column tool.

6. Enable the Gravitate command. Make sure that it is set to Gravitate to Mesh.

Note: The Gravitate command will place the columns so that they rest on the top of the mesh. These columns will be used as a guide to place the railing posts.

7. Hover over the poly line until the snap points appear. Place columns on all snap points and end points.

9. In 3D, open the Layers dialogue box and set the display to wireframe for the layer that the columns are placed on.

Note: The wireframe view makes it easier to view which hot spot you are snapping to when placing the railing.
