Category in Advanced options dialog: Drawing properties

This advanced option controls which font height system is used drawings.

• When you set this advanced option to TRUE, CAP height is used in the drawing export (DGN, DWG, and DXF) and printing (paper, plot files, PDF), and the font height is the same as the height of the capital letters of a specific font. When you use CAP height, the font height set in the Tekla Structures drawing is the same when you open the drawing in Autodesk AutoCAD or Bentley MicroStation, or print the drawing to paper or to a PDF.

• When you set this advanced option to FALSE, the em font height is used. When you use em height, and export the drawing from Tekla Structures to a DWG file, for example, the font height is converted from one unit to another (em to CAP), and the result is many times an incorrect font height.
• The default value is FALSE, and you may need to change the value to TRUE in your environment or for some of your projects.

Traditionally, the height of text in Tekla Structures drawings has been based on em (point size) font height metric only. However, some projects require the height of the text to be determined using another industry standard, CAP font height. CAP height represents the height of a capital letter more accurately than em height.

(1) CAP height

(2) point size (em)

The image below illustrates the difference in the font height in an exported DWG file when the advanced option is set to TRUE (CAP height is used) or FALSE (em height is used):

This advanced option is model specific and the setting is saved in the options database.
