By inserting HTML into your publication, you can:

• Do anything that HTML allows, including executing JavaScript;

• Insert 3D objects — interactively display interior design, architecture, and any 3D design;

• Insert video and audio players — show the layout as a video instead of an image, insert without seams between images;

• Insert images from an external source via a link — save on traffic, use images directly from your Behance portfolio;

• Insert a live demo of your interface so that visitors can interact with it without leaving the page;

• Insert interactive maps and graphs;

• Insert complex markup and typography, use CSS grids.

To insert 3D, you can use:

• Frameworks such as modelviewer.dev from Google or tinyglb.com, which allow you to show models without third-party logos;

• Hosting services such as sketchfab.com;

• Editors such as spline.design;

It is not a standard feature of CMS Framer. By default, you cannot insert HTML, so I solved this by adding a field to each part for inserting HTML code

There are 16 preset parts in every post, each with a field for regular CMS Framer content and for HTML code in that section. If you need to alternate between regular content and HTML without headers, that's no problem, you can do that too.

In the example below, Spline is not static 3D; you can click and rotate the space when it loads.
