About the Railing Tool

The Railing Tool lets you create any typical or unique Railing, which is a 3D building element. A Railing can be associative to the following 3D elements: Stairs, Slabs, Walls, Roofs and Meshes.

Railing input is similar to polyline input, and consists of Nodes and Segments. On the Floor Plan, Railing interactions are similar to those of a polyline.

The interactive Pattern Editor helps you assemble a Railing pattern specific to each Segment.

Like the Stair and Curtain Wall, the Railing Tool is a hierarchical element made up of a main scheme plus its components: various posts, rails, and/or panels. These are GDL components that use Building Materials and/or Custom profiles.

Railing Components

The Toprail sits on top of the Segment, so it always moves along with the Railing scheme. The Toprail height equals the Segment height.

The pattern can contain up to two Handrails, each of which can be doubled to the two sides of the Railing. (The two handrails can have different cross sections).

Rails are general horizontal elements. You can offset them perpendicular to the Railing Segment or set them at any height. Rail cross sections can be different for each.

You can add multiple Inner Posts to the pattern.

Balusters are a pattern within the pattern: selecting one baluster selects all its instance copies in the Pattern Editor. Panels can fill the area between the Toprail, Rails, Inner Posts or Segment boundaries.

For Panel and Post components, you can choose not just built-in GDL components, but also custom ones, saved using a predefined Railing subtype.

All horizontal elements (Toprail, Handrails, Rails) can have Connections and Endings added to either end.

For a Railing associated to a Stair, the Railing’s vertical elements can have a special connection to Stairs:

The Railing Pattern length can be set to match the number of treads.

Railings on Winder Stairs can follow the Stairs curvature.

Railing Tool Edit Mode

Use Edit mode and its dedicated component tools to access and change the individual components of a selected Rail (Posts, Inner Posts, Balusters, Toprail, Handrails, Rails and Panels).

When you select a component (e.g. Inner Post), all its pattern instances are selected, too. When opening the component settings, only the relevant geometry is highlighted and you can edit all instances at once.

Railing Display

Model View Options provides three Detail Levels (Full, Simplified and Schematic) to display and output Railings in Sections/Elevations, the 3D and 3D Document windows.

See Railing Options.
