I am working on making an Add in for Inventor with a custom form. One of the biggest headaches that i have run into is setting a picturebox to the Thumbnail image of a document. I have tried using Apprentice to get the Thumbnail property of a document, but in just throws a NotImplemented Exception. I cannot find anything i can use to save the thumbnail as an image. All other solutions that i have looked up are no longer supported on Visual Studio. So my question is, how do you set a picturebox in a form on Visual Studio to the thumbnail of an Inventor Document?
