Ⅰ. Overview

 

By entering the stair parameters, you can generate a complete set of stair railing parts with a single click using the Railing Order Splitting feature.

This tutorial focuses on the functionality available when Railing Type is set to Guardrail.

Notice: For more information about Guardrail and Staircase, refer to Railing Order Splitting (Staircase), Railing Order Splitting (Guardrail) and Railing Order Splitting (Simple-Security Grille).

2.Accessing the Feature

 

Click Railing Order Splitting in the left-side toolbar of the main interface to open the feature window.

 

 

3.Configure Parameters and Preview

 

After entering the Railing Order Splitting interface:

• • • The left panel is the Parameter Settings Area.
    • The right panel is the Model Preview Area.

The preview updates in real time according to the current parameter settings.

 

 

You can freely zoom, rotate, and move the stair model during preview:

Operation	Description
Scroll mouse wheel	Zoom in/out
Hold mouse wheel and drag	Rotate the model
Hold right mouse button and drag	Pan the view
Click Switch View	View the model from different angles
Click Initial Position	Restore the default view

 

 

Additional operations are also available in the preview area:

Open

Open a previously saved stair railing parameter file (typically a *.hdr file).

Save As

Save the current stair railing configuration. The next time you click Open, selecting the saved *.hdr file will restore all parameter settings.

Measure

Measure the distance between any two selected points.

Label

Show or hide dimensional annotations in the preview.

Preferences

Configure default preferences, such as the Handrail Measurement method and preferred Post Measurement Points.

 

4.Generate Parts

 

Click Create Part to generate a complete set of stair railing parts in the parts list.

 

 

You can navigate through the parameter pages by:

• • • Clicking Next in the lower-right corner of the parameter panel, or
    • Clicking a section title directly to jump to that page.

 

 

Regardless of which parameter page you are currently editing, once the preview matches your design requirements, simply click Create Part above the preview window to proceed to the nesting interface.

 

 

After the parts are generated, continue with the standard workflow: nesting, sorting, and exporting.

 

Ⅲ.Parameters for Typical-Security Grille

 

1.Appearance

 

（1）Style: You can choose Flat or Protruding.

 

 

• • • • Flat: The security grille is flush with the plane of the window.

 

 

• • • • Protruding: The security grille protrudes beyond the plane of the window.

 

 

（2）Joint style: You can choose Straight or Tilt. The difference lies in whether the joint is cut straight or at a 45° angle.

• • • • When Security Grille → Flat is selected, Straight and Tilt are available.

 

 

• • • • When Security Grille → Protruding is selected, Straight + Straight and Tilt + Straight are available.

 

 

（3）Makeup Position

This option is available when either of the following conditions is met:

• • • • Style is set to Flat, and Joint Style is set to Straight.
      • Style is set to Protruding, and Joint Style is set to Straight + Straight.

You can select Extend length, Extend height or Extend width.

• • • • Extend length: Fills the corner using the long side.
      • Extend height: Fills the corner using the side in the height direction.
      • Extend width: Fills the corner using the wide side. (Available only when Style is set to Protruding.)

 

 

（4）Straight Cut Position: This option is available only when Style is set to Protruding and Joint Style is set to Tilt + Straight.

You can select Length, Height, or Width.。

• • • • Length: The long side is cut straight, while the width and height sides are cut at a 45° miter.
      • Height: The height side is cut straight, while the length and width sides are cut at a 45° miter.
      • Width: The width side is cut straight, while the length and height sides are cut at a 45° miter.

 

 

2.Tube Section

 

You need configure detailed section information for the Frame, Crossbars, and Columns.

When Style is set to Protruding, Frame supports only the Square Tube cross-section.

 

 

3.Dimensions

 

You can configure detailed parameters for Installation Dimensions, Inner Bars, and Emergency Window.

 

（1）Installation Dimensions: Configure the dimensions of the security grille.

• • • When Style is set to Flat, you can specify the Length and Height.

 

 

• • • When Style is set to Protruding, you can specify the Length, Height, and Width.

 

 

（2）Inner Bars: Configure the array pattern and maximum spacing for the Crossbars and Columns on the Front, Left and right, and Top and bottom sides of the security grille.

• • • When Style is set to Flat, only the array pattern for the Front can be configured.

 

 

• • • When Style is set to Protruding, the array patterns for the Front, Left and right, and Top and bottom can be configured.

• • •  

 

(Front)

 

(Left and right)

 

（Top and bottom）

 

（3）Emergency Window

• • • Reference: Specifies the reference position of the emergency window on the security grille. Available options are Bottom Right and Bottom Left.
      •  

 

 

• • • Shear crossbar/column: Specifies the number of crossbars or columns to be removed inside the emergency window. The specified number cannot exceed the number of crossbars or columns configured in the previous step.

 

4.Assembly

 

You need configure Assembly, Technique, Quantity of Sets, and Parts List.

 

（1）Assembly

Defines how components are connected. Assembly methods can be configured for Position A and Position B. 

Three assembly methods are available:

• • • Marking layer for welding
    • Cutting layer for assembly
    • No assembly

 

Marking layer for welding	Using Position A (Flat) as an example:     A saddle feature is cut on the post, which is welded to the handrail. Welding marks are added to the handrail. No tube hole is created.
Cutting layer for assembly	Using Position A (Flat) as an example: A tube hole is cut on the handrail. The post is inserted into the tube hole and no saddle feature is cut on the post. When this assembly method is selected, Rails in tenon depth can be configured. Rails in tenon depth specifies how deep the post is inserted into the handrail during assembly. It affects connection strength and stability and should be set according to actual application requirements.
No assembly	Using Position A (Flat) as an example: A saddle feature is cut on the post, which is welded to the handrail. No welding marks are added and no tube hole is created.

 

(2) Technique

For cutoff line, the following options are available: Weld Seam Compensation, Bevel and No Technique.

For tube holes, the following options are available: Intersect Hole, Maximum Outline, Bevel and No Technique.

(3) Quantity of Sets: Specifies the number of stair railing sets to generate.

(4) Parts List

• • • Parts Name: Supports custom part names. By default, part names are generated based on the component type and dimensional parameters.
    • Total: Displays the quantity of each part required for the selected number of sets.
    •  Length (mm)Qty: Click the top right corner to obtain the required tube length and quantity for the generated parts.

 

*The displayed length is for reference only. Actual part lengths shown in the cutting software shall prevail.

 

 

Ⅳ. FAQs

 

1.Can the generated parts be modified in the Draw Part (TubeDraw) interface?

 

No. If you need to edit the generated parts, use the Add Stair Part feature instead. Although it cannot generate a complete stair railing set automatically, the resulting parts can be modified afterward.

 

2.How can identical parts be merged?

 

Enable Merge Identical Parts in User Settings. 

 

 

3. What should I do if the default dimensions do not match my measurement preference?

 

Click Preferences on the top toolbar and select the desired measurement preference.

You can choose the option that best matches your measurement habits.
