Description

I am trying to place a Rail to go along the Ramp and its curvature, however the Rail tool seems to be non-associative with objects. As a workaround, here’s a guide on how to efficiently create a rail that is adjusted to the ramp's curvature.

Solution:

1. Select your preferred Ramp type in the Object Default Settings Dialogue and adjust the Ramp Settings according to your needs.
2. Place the Ramp in the plan followed by tracing the Ramp’s Arc length with an Arc/Circle tool.
3. Move the traced Arc away from the Ramp then place the Rail along the Arc using the Magic Wand tool.
   

4. Move the newly created Rail over the Ramp.

5. In the 3D View, (activate the Edit mode) edit the Rail baseline elevation manually according to the ramp's gradient.
