<div>Andreas,</div>

<div> </div>

<div>I regularly use TikZ for (3-D) graphics in LyX.  Unfortunately, there is no built-in editor, so I tend to create the images in <a href="https://github.com/fredokun/TikZ-Editor" target="_blank">TikZ Editor</a> (or just my favorite text editor), save the .tex file, and then use Insert -> Child Document -> Input.  </div>

<div> </div>

<div>Many of the images for <a href="https://www.sciencedirect.com/science/article/pii/S0306454917304991" target="_blank">this article</a> took the aforementioned approach when preparing the manuscript in LyX.</div>

<div> </div>

<div>Hope this helps,</div>
