How to view a file in the WinForm Application

I have a 3D file with the suffix. STL, According to GroupDocs.Viewer, can it view in the WinForm Application?
does GroupDocs.Viewer have WinForm UI Control?

@LuoSanhong,

Yes, you can use GroupDocs.Viewer for .NET in your WinForms application. The API doesn’t contain any built-in control or the UI, instead, you will have to create it on your own. The API provides the following ways to render a document/file:

Once you have the rendered HTML pages or images, you can display them in your application. For example, you can use a WebBrowser control for viewing HTML pages or PictureBox control for viewing images in your WinForms application.

Thank you so much for your answer

@LuoSanhong,

You’re welcome.
