How to do it

the tool · the steps · what to avoid
  1. 1

    Open the PDF file in Adobe Acrobat (Pro version required).

  2. 2

    Navigate to the page where you want to insert the 3D model.

  3. 3

    Select Tools from the top menu, then choose Rich Media.

  4. 4

    Click Add 3D and draw a rectangle on the page to define the area for the 3D model.

  5. 5

    In the dialog that appears, click Browse and select your 3D model file (U3D or PRC format).

    CautionOnly U3D and PRC file formats are supported for 3D embedding in Acrobat.

  6. 6

    Adjust the 3D settings as needed (e.g., poster image, activation, navigation options).

    Best practiceFor best compatibility, use a simple poster image and limit initial activation to 'When page is visible.'

  7. 7

    Click OK to embed the 3D model into the PDF.

  8. 8

    Save the PDF to retain the embedded 3D content.

You can interact with the embedded 3D model in Acrobat by clicking and dragging to rotate, zoom, or pan the object.

This runs in the Acrobat app - there is no separate API for this task.

FAQ

about this task

To embed a 3D model in a PDF with Adobe Acrobat, you use the 'Rich Media' or '3D Tool' to place the model file, such as a U3D or PRC file, into your PDF. This lets people view and interact with the 3D object inside the document.

PDFs made with Adobe Acrobat usually support 3D models in U3D or PRC formats. Other 3D files, like .obj or .stl, need to be converted to these formats first before you can embed them.

Embedding a 3D model in a PDF lets viewers see and move around the object, which is helpful for showing designs, explaining products, or making instructions clearer.

You cannot change the 3D model itself inside the PDF. If you want to update the model, you need to edit the original 3D file and then replace it in the PDF.

A picture is flat and only shows one view, but a 3D model lets people turn, zoom, and look at the object from all sides inside the PDF.
