Store embeded U3D from PDF using Spire.PDF

[procamSpire]

Hi Spire!
Please how to extract/store embeded 3D model from PDF to U3D file using Spire.PDF?

Universal 3D (U3D) is a compressed file format for 3D computer graphic data. 3D modules in U3D format can be inserted into PDF documents and interactively visualized by Acrobat Reader.
So I need the reverse operation as in your Tutorials > Spire.PDF > Program Guide > Image > "How to Embed 3D Interactive Graphics into PDF Document in C#, VB.NET".

BR,
Vlado

To extract an embedded U3D model from a PDF using Spire.PDF, you'll need to check the library's documentation or forums for specific methods. It might involve accessing the PDF's resources or elements to extract and store the U3D data separately. Look for functions related to extracting embedded objects.
