Unable to find an entry point named 'CSharp_OpenStudio

Hello everyone,

I’m a longtime user of DesignBuilder, but I’m trying to switch to other workflows
SIMULACAO LBforum.gh (590.6 KB)
(even though it is by far the best tool of its kind, I just can`t afford the DB license). I tried OpenStudio, but I couldn’t install the SketchUp plugin. Now I’m trying to use Honeybee simulation with EnergyPlus, but I’m having some compatibility issues with OpenStudio.

I found a similar question in this forum, but I couldn’t get it to work. I’m getting the following error message in the “Export to OpenStudio” component:

Solution exception: Unable to find an entry point named ‘CSharp_OpenStudio_toPath__SWIG_0’ on DLL ‘openstudio_csharp.dll’.

Here are some things I’ve tried (not in any particular order):

  • I’ve tried different versions of OpenStudio: 2.7, 2.9.1, 3.0.0, 3.2.0, and 3.5.1.
  • I’ve tried installing OpenStudio in the LB folder, as suggested in another post about a similar problem, but the software wasn’t recognized.
  • I’ve updated to version 1.7 of Honeybee through the Pollination site.
  • I’ve saved the openstudio.lib and dll files in the csharp folder.

I’m really hoping someone can help me with this. Thanks in advance.

Hello Rvenacio,

I’m facing the exact same issue with the LB tool legacy even tough Openstudio from pollination works for me. I haven’t been able to resolve it therfore I’ve posted a topic in another group where there are more people. Hopefully, someone there has successfully addressed this problem.
