New Stairs & Updated Railings!• The old stair tool is still there.• New stair tool is “component based”

– Broken down into parts and pieces– Addresses:

• Overlapping Stair Runs• Divergent Stair Runs• More complex geometry

o Supportso End geometryo Materials

Component Based Stairs

• Stair Construction Families (system)– Metal Pan/Wood (Assembled Stair)– Cast-In-Place Stair (Monolithic)– Precast Stair (Precast Stair)

Component Based Stairs

• Components (system families)– Supports – Stringers (closed) &

Carriages (open)– Landings – Monolithic & Non-

Monolithic– Runs – Monolithic & Non-

Monolithic– Cut Marks – annotation

elements, but part of the Stair Category

• Profiles – Tread, Riser, Nosing, Supports (new profile types)

Component Based Stairs

• Demo Time!!

Precast Stairs

• System Family• Default uses same run type

as Monolithic.• Must pay attention to End &

Begin with Riser parameter for notch connection to work!

• Can be joined to (cut) floors.– Plan graphic issue (reported)

Object Styles/Visibility Graphics• New Subcategories• Includes “annotation” elements.• Finer Level of Detail

Annotation Enhancements

• Select Filter Recognizes differentSubcategories.

• Some Annotation families areSystem Families:– Cut Lines– Stair Path– Stair Tread/Riser Number Tag

• New & Improved Tags– Stair objects (Run, Landing, Support)– Stair (number of risers & treads)

• Equality Formula (Dimensions)

Stair Paths

• More Flexible– Editable in Stair Sketch Mode– Adjustable Grips

• View Dependent– Cannot Copy/Paste– Place New– Duplicate View with Detailing

Railing Improvements

• Railing transitions and extensions to top rails and handrails improvements.

• Auto-placement of continuous rail elements.

• Railing can be previewed during sketching.

Railing parameters

• There are now additional parameters to control railings.

• You can include one or two Handrails – 1 & 2

• Handrails are driven by Type properties, but you can override their type to make local edits.

Railing family type

• Understanding the family types is essential

• Review the Project Browser to better understand the different families & their structure

Railing Topology simplified

Continuous Top rail

Handrail 1 or 2 (handrail type

-system)

Support (family)

Termination (family)

Railing positions

Top rail

Handrail 1

Handrail 2

Railing Positions

• Be aware of this error!

• In essence you have the same railing TYPE in the same position • You need to create a new railing TYPE for each of the Handrail

parameters 1 & 2

The Basic Edit Rail process

• This works for continuous top rail & hand rail

• “Tab” select the rail

• The Edit Rail command becomes available from the Ribbon.

• Choose Edit Rail, to modify the settings of the Rail

• To edit the Rail Path, choose the Edit Path icon, to make further edited

• Further tweaks can be made to the path if required, such as Filleting Joins.

Category Control

• With the Railing improvements, we now have increased list of railing categories.

Construction - Transitions• Improved transition, allowing better geometric joins of the rails.

• Simple• None • Gooseneck

Extension – Extension Style• Potential Extension Styles, possible at the top & bottom of a rail• These work for top rail & hand rails 1 & 2

• Post • Floor• Wall

Default Joins

• There are two options for Default Joins for railings

• Fillet• Miter

Default Joins

• Be aware, “IF” your Fillet Radius is too big, fillet join will fail!• In the example below, a 10mm radius causes an error.

Supports & Terminations• Supports & Terminations are new to Revit 2013• They have their own unique category types• You build a Support or a Termination from a new family template• No obvious template!• Start with a generic model & then select the appropriate

category

• Terminations

• Supports

Preview Railing

• When placing a railing, there is a new option; if “checked” allows you to preview the railing as you sketch the path.
