Question:
Area selection leaves a pink / magenta color on the screen. How can I avoid that?

Answer:
This problem is caused by a bug in Nvidia drivers, and it occurs only on Nvidia graphics cards and only in OpenGL rendering. Tekla Structures 2019 does not have this problem.

For customers using Tekla Structures versions 2017 - 2018, we have provided a fix in the following service packs (and newer):

  • Tekla Structures 2017 Service Pack 9
  • Tekla Structures 2017i Service Pack 5
  • Tekla Structures 2018 Service Pack 2
  • Tekla Structures 2018i Service Pack 1

 
For customers using Tekla Structures versions 17.0 - 2016i, we provide the fix in separate Zkit dll files. You can download the needed dll file(s) from Tekla Warehouse: OpenGL Rendering Fix. When the old Zkit dll file is replaced by the new one, the pink area selection traces will not appear anymore.

When replacing the old Zkit with the fixed one, please check that

  1. The correct Zkit dll file version is used for each Tekla Structures version
  2. The fixed Zkit dll file is copied to the correct location (normally C:\Program Files\Tekla Structures\<version>\nt\bin)
  3. The original Zkit dll file is removed
