arrow in the Arrow list in the Dimension Properties dialog box, you can create and use an arrow of your own.

First you need to create the arrow symbol in the Symbol Editortool in Tekla Structures that is used for creating and modifying symbols to be used in drawings, reports, and templates

The symbols are saved in symbol files.

, and save the created symbol in the dimension_arrows.sym file. Then you need to add the position of the new symbol in the dimension_arrows.sym file to the configuration file dimension_arrows.txt file. This file tells which arrows are available for use in your environment. Finally, you need to create a bitmap for the new arrow to be used in the Dimension Properties dialog box.

  1. On the File menu, click Editors > Symbol editor to open the Symbol Editor.
  2. Open the dimension_arrows.sym file located in the Common environmentTekla Structures environment that forms a basis for other environments

    The common environment is included in the software installation and includes the global settings, macros, symbols, items, and fonts, for example. The common environment and global settings form the basis for all other environments.

    ( ...ProgramData\Trimble\TeklaStructures\<version>\Environments\common\symbols ) or in your environment under the \symbols folder.

    You can also import AutoCAD or MicroStation files through File > Import .

  4. When the symbol is completed, point the symbol slot to check the number of the new symbol at the bottom of the window.

We recommend you define a firm folder for symbols, because the default folders are overwritten when you upgrade to a newer version of Tekla Structures. Add the firm folderfolder that is used for storing Tekla Structures-related files customized for a particular organization

A Tekla Structures user can, for example, customize a company’s cloning templates and save them in a sub-folder located under the firm folder. After this, the customized cloning templates can be used in all projects carried out for the company.
