Custom Elements (Extension API) with point/mesh selection

[[Ma...]]

In the new custom elements feature (https://zeiss.github.io/zeiss-inspect-app-api/2026/howtos/custom_elements/custom_nominals_actuals.html), is it possible to create an element based on a point selection in the 3D view?

For example, let's say I want to implement a RANSAC based fitting circle.  I want the user to select points from a cross-section, rather than simply providing the whole section element, which I will then run RANSAC on.

Is that possible with the current 2026 software?  

Thanks!
