Purpose and description

Use Spiral staircase to create and model a spiral staircase.

System requirements

Tekla Structures version: 2017, 2017i, 2018
Environments: All

Installing Spiral staircase

To install the extension:

  1. Download the Spiral staircase installer package from Tekla Warehouse. For more information see Downloading an application from Tekla Warehouse.
  2. Install the file package.

Using Spiral staircase

To use the application:

  1. Open a Tekla model.
  2. Click the Applications & components button  in the side pane to open the Applications & components cataloguser interface for displaying or modifying information in categorized lists

    For example, profile catalog and shape catalog are catalogs.

    .
  3. Search for Spiral staircase   and then double-click to open it.
  4. The Spiral staircase dialog will open.

Note:
To import items follow these steps:

  1. On the File menu, click Catalogs > Shape catalogcatalog that displays a list of predefined item shapes

    The shapes are modeled using software other than Tekla Structures, for example SketchUp.

    .
  2. The Shape Catalog dialog box opens.
  3. Click Import.
  4. Select the import file.
  5. Click OK.

- supported shape file types are: .tsc; .skp; .dxf; .dwg; .ifcfile format commonly used in BIM that facilitates software interoperability

IFC is an open specification developed by the IAI (International Alliance for Interoperability).

Model can be exported into an IFC file.

; .ifcZIP; .ifcXML; .igs; .iges; .dgn; .stp; .step
