nora stairtreads ArchiCAD 21+ library part

Diverse variants of stair coverings from nora systems can be configured in detail and in the real material

thicknesses using this highly configurable library element.

Functions and properties -Adaptation to treads, risers and polygonal landings

-Material thicknesses identical to original coverings

-Texture origin and alignment can be rotated by entering parameters

Included files Unzip the zipped folder. Save the ArchiCAD library file "Nora-Rubber-Floorings.lcf" locally on your computer, on

a server or on a BIM server.

The unzipped folder contains further useful files and documents whose use will be explained later on: PDF

manuals, attribute files for ArchiCAD 17–22 and list schemes for list analysis. All files are adapted to the

language version (DE/EN/FR/ES) of the respective ArchiCAD object. The folder also contains a sample

ArchiCAD_21 file in the format *.PLN "nora_stairtreads_example_AC21_2018_001.pln".

Loading the library Upload the file "Nora-Rubber-Floorings.lcf" into your current project. This LCF file contains a library part. The

library provides all BIM parameters and texture data necessary to plan the entire rubber floor covering range of

nora systems from Weinheim in detail in 2D and 3D. It can also be used for evaluating lists later on.

The floor coverings library can be used in versions starting from ArchiCAD 17. However, the stair coverings

library can only be used in versions starting from ArchiCAD 21, as the stairs tool was introduced in this version.

The LCF file contains one library element for each of the two floor covering types.

Preliminary remarks on using the stairs tool The ArchiCAD 21 stairs tool is a completely new tool providing new, comprehensive functions and a wide range

of modification and editing options. This manual only describes how to use the stairs accessories when using the

tool. Users should already be familiar with using the stairs tool. Please use the online help system or Graphisoft

Youtube channel to find answers to any questions concerning the ArchiCAD stairs tool itself.

The newly developed object "NORA-Stairtreads“ for ArchiCAD from version 21 is a BIM-compliant accessory

component.

It can be used to realistically visualise norament® stairtread products from the nora systems product range in 2D,

3D and renderings.

norament® stairtreads are special rubber floor coverings for stair treads. In the BIM format presented here, these

can be seamlessly integrated into the stairs workflow created using the ArchiCAD stairs tool.

The interactive evaluation option can also be used to output detailed component lists for the floor coverings used.



Stair tool global settings To use the object, activate Tread or Tread and Riser in the stairs tool under Cladding.

As the nora® object is a tread accessory, it is sufficient to just select Tread.

The nora® object is primarily intended for use with stair coverings for solid concrete stairs. However, it can also

be used to cover stairs that already have treads or treads and risers (e.g. for renovation or refurbishment; see the

relevant information below).

It is only possible to define treads or treads and risers one time for each staircase. In a case such as this, the

treads would be defined as parts of the nora® stairtreads but the risers would not (see below for further

information).

Important information for the general stairs tool work process: The stairs tool provides the option of configuring all settings globally. This means that every setting made in the

Stairs Selection Settings dialog box changes every component that belongs to the stairs and that has not yet

been detached (see below for explanation) on all tabs.

-IMPORTANT-

It is vital to select the only angle possible (80° to 90°) for the front edges of norament® stairtraids treads globally

at the start. This is for technical reasons connected with the product itself and the selection of stair accessories

configured for the original product. Selecting other angles would cause errors in the visualisation and subsequent

real-world implementation on the construction site would be impossible.



Furthermore, every stair component that is based on a separate GDL object, e.g. each individual tread, flight or

landing, can be detached from the global stairs settings for editing.

This works the same in Plan, Section/Elevation and 3D views:

Highlight the entire stairs

Click on the floating Edit field

Click on a certain component, e.g. a tread, to activate it (hold down the SHIFT

key to activate multiple treads)

Make the required changes to the component or components whilst detached

from the complete stairs

End editing mode

If you have edited certain elements with them detached from the complete stairs, any changes made to the

complete stairs (global changes) will not cause any changes to be made to the detached components.

This is indicated in the left half of the Stairs Selection Settings dialog box by a stair component marked with an

exclamation mark in a yellow triangle – a tread in the example shown here.

This means that individual changes have been made to one or more treads and that these elements are therefore

detached from the global settings.

You can click on the button Reset Treads at the bottom of the dialog box, but BE CAREFUL:

If you do this, all detached tread settings will be reset to the global settings, which is undesirable in most cases.

It is highly likely that you will need to edit treads in detached mode when

configuring nora® tread coverings. For this reason we recommend using the

following general work procedure for stairs:

Edit all settings that are globally applicable at the beginning as far as

possible.

Edit detached treads at the end as far as possible.

Avoid using the Reset Treads button unless you are sure that you really

intend to do this.

Nevertheless, you may still wish to change the material or colour of the

entire stair coverings after completely configuring the stairs.

In this case, change the material globally, highlight all detached treads

together in Edit mode as described above, and then change them

separately.



The user interface All parameters are entered via the user interface. Select the object "NORA-Stairtreads" from the Tread tab of the

stairs tool dialog box.

-IMPORTANT-

It is vital to select the appropriate language version of the object at the start. Now enter the product family,

product, pattern and colour in the logical sequence.

ArchiCAD surface materials, BIM parameters and thicknesses are automatically transferred to the object and

displayed in the user interface views; these can be used for list analysis later on.

Page 1: Surface Define your specific stair covering selection working from top to bottom. The options follow the product logic of

the manufacturer's floor covering designation. First, select the product family: only norament® is available in this

field.

The respective product family products are shown below for selection: 926, 926 grano and 926 satura.



Specification There is only one stair-specific selection provided: steptread

The item number field contains 3 values that can be selected for each product. The item numbers only indicate

different covering widths. The width is automatically transferred to the Covering Width field when the item number

has been selected.

The Thickness field also receives the product/BIM parameters automatically, so neither of these fields can be

edited.

Colour/pattern selection Select a colour by either A.) using the fly-out menu containing miniature previews or B.) selecting the colour

number if you have the colour number from the collection. (These two fields are also related to one another).

Page 2: Representation

Global settings for the stair covering design and the design of individual steps and landings are made here: If the

complete staircase is highlighted, all settings made in this view will apply globally. If individual steps or landings

are selected, the corresponding settings are only made for the selected sub-elements without affecting the non-

selected sub-elements.



Step edge smoothing Use this field to select the level of smoothing to be used on the rounded step edge: standard, smooth, rough,

edgy. This value is used for visualisation in 3D views and renderings. The smooth level requires the highest

processing power.

Round inner edge to riser covering If this checkbox is activated, the rear transition from tread to riser will be rounded instead of angled.

You also have the option of entering a radius when selecting

a rounded transition.

Tread on/off This checkbox refers to a tread underneath the nora® covering, e.g. a wooden step on a supporting concrete

core. More information can be found in the section titled Renovation.

Riser covering on/off This checkbox switches risers coverings on or off. If the risers do not have to be globally covered, remove the

checkmark from this checkbox. The checkmark is set as standard because the product is intended for continuous

coverage of treads and risers.

If the stairs end with a tread at the top, select the top step and deactivate the riser covering for this individual step

as no further riser is present above the step.

From here only editing of single steps or podiums The following settings are used almost exclusively to edit individual steps and landings instead of changing the

global stairs settings. Therefore, this area can be disregarded when initially setting up the stairs.

Riser covering underneath the step This checkbox generates a riser covering underneath an individual activated step. For instance, this is always

necessary if a landing is present. No riser covering is provided as landings cannot be covered using steptread

components (because they consist of a step edge and normal floor covering). A riser covering can be activated

on the step located above the landing.

There is no need to manually add the note "Step edge and normal floor covering". It is visually matched with the

remaining stairs automatically. (See next point) Step is platform area There is no suitable nora® stairtreads product for stairs that include one or more intermediate landings.

Furthermore, the stair covering geometry does not fit the landing. Therefore, activate the individual landing or all

landings by activating the Step is Platform Area checkbox. This adapts the floor covering to the landing and

simulates a covering from the „NORA Rubber Floorings“ range along with a step profile. The riser located above

is not covered, which is why the previous point must be observed.



Texture origin on/off and Texture angle For all steps that are not landings, the texture origin is created to match the nora® products.

It can be useful to offset the texture origin for landings. In this case, activate the checkbox and enter the

coordinates and angle of rotation manually. When this checkbox is activated, a coordinates cross is displayed at

the texture origin in the 3D view to illustrate the origin. The cross disappears when the checkbox is deactivated,

but the offset and angle of rotation are retained. Texture offset only relates to the simulated Rubber-Floorings

floor covering on landings.

Step without NORA floor covering In some situations, it can be helpful if no nora® stair coverings are shown on individual steps or landings, for

instance, if the geometry is very unusual and prevents the object from visualising them correctly, or if a floor

covering other than a nora® stair covering must be installed.

Page 3: Product data All relevant BIM data and product data of the covering specified on the Surface tab can be found on sub-tabs -1-

to -3-. The data present in fields marked with an i cannot be edited and are used for list analysis.



Sub-tab -4- contains links to the country-specific manufacturer website, further accessory information, tender

documents and an Update button. You require an Internet connection to use this button. The object checks

whether it is still up to date. If an update is available, the current data can be downloaded from this website.

-NOTE-

Please save your ArchiCAD project and the previous LCF file separately before updating "Nora-Rubber-

Floorings.lcf" .

Renovation/refurbishment If you wish to renovate an existing staircase consisting of,

for example, a supporting concrete core with wooden treads

and risers that already exists in your ArchiCAD project,

please proceed as follows:

- The existing stairs have a supporting concrete core

and are clad with treads and risers

- Now replace the existing tread coverings using the

module Nora-Stairtreads

- Activate the Tread On/Off checkbox on the

Representation tab and enter a tread thickness in

the upper part of the dialog if no thickness is yet

present

- You can retain the riser coverings from your old

settings, if present, or remove them
