Category in Advanced options dialog: Drawing views

Use this advanced option to select the drawing rendering engine. The options are GDI and FOG.

Orginally, the need for new drawing rendering was caused by a Windows update that could cause serious issues in drawing rendering in Tekla Structures. This was related to the Windows GDI and depended on the hardware used. Later Windows updates or updates of your hardware might have diminished or even removed the problem.

By default, this advanced option is set to GDI, which means that the Windows Graphics Device Interface (GDI) rendering is used.

When set to FOG:

• The overall rendering is faster, which can be seen when you pan or zoom, for example.
• FOG rendering does not use GPU.
• There are some limitations in FOG rendering, which may cause the need to use the GDI rendering instead:
  • The line widths are sometimes inconsistent.
  • Lines and fonts are sometimes less distinctive than when using GDI.
  • In FOG rendering, there is a slight offset in the placing of texts.

You can change the rendering engine while in an open drawing. The drawing is immediately redrawn using the current rendering engine.

This advanced option is user specific and the setting is saved in options.bin under the user folder, for example, in C:\Users\<user>\AppData\Local\Trimble\Tekla Structures\<version>\UserSettings.
