You can attach railings to one or both sides of a stair, and you can wrap them around a landing. You can also attach railings to any other type of AEC object, like a massing element. You can create a custom railing by converting a polyline. Therefore, railings can have a variety of shapes and can be anchored to a straight stair, a multi-landing stair, a U-shaped stair, or a spiral stair. You can create custom railings by specifying custom blocks and profiles to be used for individual railing components. You can assign profiles to railing components by style so that you can reuse the custom portion to create detailed railings.
