Use the new Staircase Generator to create single-flight, straight stringer staircases with intermediate platforms - with or without utilisation of stairwell contours. Individual settings, such as various stringer or step variants, as well as various connection options for stairs to stringers, or the definition of standardized platforms are available.

A prerequisite for the start of the Staircase Configurator is that the current drawing contains a main assembly. If this is not the case, a corresponding message will be displayed.
Extensive information on main assemblies can be found in the topics
Assemblies, Main Parts and Sub-Parts,
Part Drawing or Assembly Drawing and
Edit Part/Assembly Structure .
After calling the Staircase Configurator, HiCAD will prompt you to identify the stairwell, or to press the middle mouse button if you want to work without stairwell.
Working with stairwell contours
Here you fit the staircase into a stairwell. For this to happen, a suitable sketch for the stairwell must exist in your drawing. This sketch serves the purpose of positioning the staircase in the stairwell and defining the stair start (the so-called "entrance"). Therefore, the first step will be creation of a stairwell with the help, of the functions on the Sketch tab.
The length of the stairwell must not be smaller than the total length of the staircase. If this is the case, HiCAD will display an error message.
Identify the sketch in the vicinity of the stair start.
(1) Identified sketch, (2) Sketch length, (3) Distance at stair start, (4) Distance at stair end, (5) Walking direction
If you work without a stairwell contour, the fitting point of the staircase will be placed in the origin of the World Coordinate System. You can freely select this fitting point when you insert the staircase.
The input fields of the Staircase Configurator dialogue window will always be initialised with the last saved values when you open it to create a new staircase.
The window consists of the following tabs:
Specify the desired staircase parameters on the tabs.
Click OK to start the staircase generation.
If the Check conformity checkbox has been activated, HiCAD will first check whether the staircase can actually be constructed on the basis of the specified parameters. If this is not the case, the 
symbol will be shown on the OK button. In the dialogue window, fields with an incorrect value will be marked with the 
symbol. Move the cursor over the symbol to obtain further information, and correct the staircase parameter. You can click on the Set parameters according to standard button to correct the parameters automatically.
If the check was successful, HiCAD starts with the staircase generation. The current status of the generation will be indicated by a progress bar at the bottom of the window. A feature called Stairway will be entered in the Feature log.
Working with Favourites
The settings specified in the dialogue window can be saved as favourites and re-used at any time if desired. To do this, click the 
symbol at the bottom left of the dialogue window.
More information on favourites management can be found in the Manage Favourites topic of the HiCAD Basics Help.
On this tab you specify the size of the staircase, the number of steps and platforms.
Here you choose the type of the stair start by clicking on the corresponding symbol. The graphic in the dialogue window will then be automatically adjusted accordingly.

Depending on the stair start type you then specify the height of the finished floor and the platform length. If a flooring will be used, which requires the taking into account of an "unfinished floor", enter this value here, too.
If you choose "Entrance stringer with pillar", the height of the pillar will be automatically calculated automatically, based on the value for the unfinished floor.
Here you choose the type of the stair end by clicking on the corresponding symbol. The graphic in the dialogue window will then be automatically adjusted accordingly.

When you work with a stairwell contour, you can specify the stair start and the stair end (distance of stair start and stair end to stairwell), as well as the stairwell length here. When you work without a stairwell contour, these fields will be greyed out.
Besides platforms at the stair start and the stair end you can also insert intermediate platforms. To do this, activate the corresponding checkbox and enter the platform length.
The parameters for the steps are as follows:
You can enter one of the parameters a, u and α here. To be able to do this you need to activate the radio button next the the input field. The other values and the Rise s will then be calculated on the basis of the entered value and the values entered for Total number of rises and Rise before intermediate platform in the Dimensioning area of the dialogue window.
The step depth results from the step variant chosen on the Steps tab of the dialogue window.
Here you can specify the Total number of rises and Rise before intermediate platform.
The other values will be automatically calculated by HiCAD on the basis of the specified parameters:
Basis for calculation
In the listbox you can choose the guideline to be respected for the calculation. These guidelines, e.g. national regulations for stair construction, are specified in the Configuration Editor at Steel Engineering > Products > Staircase > Guidelines. The regulations according to DIN 18065 have ben pre-set here. For defining further guidelines, right-click on one of the existing guidelines and choose Derive structure in the context menu.
If the Check conformity checkbox has been activated, HiCAD will first check whether the staircase can actually be constructed on the basis of the specified parameters. If this is not the case, the symbol will be shown on the OK button. In the dialogue window, fields with an incorrect value will be marked with the symbol. Move the cursor over the symbol to obtain further information, and correct the staircase parameter. You can click on the Set parameters according to standard button to correct the parameters automatically.
To place the cursor in a particular input field, you can also click on the corresponding markers in the graphic of the dialogue window. If, for example, you click on the marker in the graphic of the Calculation tab, the cursor will be placed in the Unfinished floor input field.
On this tab you can specify the stringers to be used for the staircase.
First select the variant:
Then, enter the base offsets for platforms and stairs.
Select - depending on the selected stringer variant - the beam or the plate/sheet from the HiCAD catalogue by clicking the 
symbol. In the case of Sheet Metal stringers you need to specify the parameters Width, top (1), Width, bottom (2) and Height (3).
If you use Sheet Metal U stringers, specify the desired values for Width, top (1), Height (2) and Width, bottom (3).
If you use Sheet Metal C stringers, specify the desired values for Width, top (1), Height (2), Leg length (3) and Width, bottom (4).
Here you specify the data for the entrance, landing and intermediate platform.
Specify the distance of the entrance platform at the front, and the landing platform at the rear. If you want to use the same data for different platforms, activate the All equal checkbox.
Grating
Currently only grating platforms are available. Click the symbol and select the desired grating from the catalogue. Enter a distance to the stringers.
Support profile
Select the support profile from the catalogue by clicking the symbol, and specify its size - either by entering the edge distance or the length.
Connection Support profile - Stringer
Activate this checkbox if you want to create a connection between support profile and stringer. You can choose between a bolted and a welded connection.
Connection Grating - Support profile
If desired, proceed likewise to specify the bolted connection between grating and support profile .
Here you specify the data for the stair steps.
Variants/Material
Select the desired variant and enter the required data.
(1) Sheet Metal step, (2) Sheet Metal step without support profile - Corner processing: Rectangular cut-out (3), Circular cut-out (4), Closed (5)
Support profile
Select the support profile from the catalogue and specify its length.
Connection, Stringer
If you want to create a connection between support profile and stringer, activate the corresponding checkbox. You can choose between a bolted or a welded connection. Please note however that bolted connections are only possible for particular support profiles, e.g.for L-beams.
Connection, Step
If desired, proceed likewise to specify the bolted connection to the step.
On this tab you specify whether (and which) assembly joints between staircase sections are to be created.
One distinguishes between:
Boltings can be installed as loose parts or be assigned to the assembly of the respective level. Activate the desired option. When installing them as loose parts the bolting connections will be assigned to the Accessory Parts assembly.
