Maybe there is someone who has worked with the Tekla Open API - you are my last hope! I need to check whether there is a preview in the model or not. If not, then you need to create it using the Tekla Open API. Maybe someone has already come across such people and knows how to do this, please tell me.) And I wrote down a macro, thought that it would help me somehow (wpf.InvokeCommand ("CommandRepository", "Tools.CreatePreviewImage")), but no, miracle did not happen.
How to make a check whether there is a preview in the model folder, I know. And I also know that when you manually create a preview, it is thrown into the model folder and is named thumbnail.png by default.
