How to export your model to IGES/STEP/OBJ/STL/IFC


In this article we will explain the process needed to export your Tekla model to IGES, STEP, OBJ, STL, and 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.

formats. In prior versions we used the STEP/IGES converter to export to IGES or STEP. With the new 2016 version of Tekla Structures we can now export to more formats.


Prerequisites

Before you start, you need to get the Multi Format Converter from Tekla Warehouse. Please note that you must be logged in to see the download buttons.

Getting started with the Multi Format Converter

First, open Tekla Structures and open the model you wish to export. Then, go to Applications and Components catalog and search for Multi Converter. 

 

Once you open the tool a dialog box appears:

 

The options:

  1. 1 file by part markmark that includes a set of selected property elements related to a part

    Part marks are used for identifying constructions, for giving information about welding, for giving information about assemblies to a workshop, for giving information about how parts should be connected to each other, and for creating bills of quantities, for example.

    In the US, the term piece mark is used to refer to position number.

    - This option will create one file per part mark and label the file with the part mark. For example, if I have 10 C1's, 4 C3's, and 2 B2's and I run the converter I will get 3 files named C1.ifc., C3.ifc., and B2.ifc.. When using this option there is an option called include quantity at the bottom of the screen. If you select this check box the quantity will be included in the file name. 
  2. 1 file by assembly mark - This option is similar to the 1 file by part mark except it will export one file per assembly mark. This is to say, only 1 file per assembly and per assembly mark will be exported. When using this option there is the check box for including quantity in the file name at the bottom of the screen.
  3. 1 file by object - This option gives you one file per object in the model, so if you have 50 parts in the model you will get 50 files. These files are named with the object ID number and you cannot adjust the naming schema. When using this option you can choose to include or exclude bolts.
  4. 1 file by phase - This option allows you to use the already created phases in your model and export one file per phase. When using this option you can include or exclude bolts.
  5. 1 file for all - This option allows you to export the entire model to one file. Bolts can be excluded or included.

The export formats:

  1. IFC  - When using this tool  you can export each file with the part mark name, assembly mark name, or by one object. If you use for example Solidworks which accepts IFC files you can export files using this option and get one file per part mark to send to Solidworks for fabrication. This option also has a drop down menu to choose the settings you want to use. You can create new settings by going to File > Export > IFC.
  2. STP -  This exports the model as STEP AP214.
  3. IGS - This exports the model in IGES format.
  4. OBJ - This is a Geometry definition file (not extrusion) and can be used for 3D printers and renderingprocess of making the model object faces visible

    The rendered model object faces can be transparent or non-transparent

    softwares.
  5. STL - This format is something we have used in the past and you could export this format by utilizing the older tool called "rapid prototype". This format is also used mainly for 3D printing 

NOTE: When creating files using this tool it will always delete the old files when you convert new files. So if you want to keep the existing files you have before you create new ones you need to copy and move them to a new folder.
