length using advanced optionssettings used to customize Tekla Structures for specific companies, standards, users, or user groups

In Tekla Structures, advanced options are settings that are used, for example, in a specific project or geographical area, or by a specific company.

In Tekla Structures, advanced options usually begin with the initials XS and are followed by the name of the function, for example XS_BACKGROUND_COLOR.


You can load the dimension properties file where you have the correct setting when you add automatic dimensions on view level.

  1. Open a drawing and double-click a dimension.
  2. Go to the General tab of the Dimensions dialog box.
  3. Select an option from the Short extension line list:





    Use this option to create extension lines all of the same length:

    On grid lines only

    Use this option to use the short extension line automatically if a dimension line falls on a grid line. Elsewhere the extension line will be as usual.

  4. Save your setting in a properties file for later use.
  5. Click Modify.
  6. To adjust the extension line lengths, go to File menu > Settings > Advanced options > Dimensioning: General and set the following advanced options. These advanced options adjust the extension line length in relation to the text size:

  1. Text height * 1.0 (default). Use XS_​DIMENSION_​EXTENSION_​LINE_​AWAY_​FACTOR to adjust the length of the dimension extension lines that are facing away from the dimension points.
  2. Text height * 1.5 (default). Use XS_​DIMENSION_​EXTENSION_​LINE_​TOWARD_​FACTOR to adjust the length of the dimension extension lines that are facing towards the dimension points.

These settings work only if "Short extension line" is "Yes". I suppose the AWAY_FACTOR sholud work in any case at least.
