Calculate a surface

However, is there any other approach without having to introduce any script?

There might be different extensions with all the tools to make this processing workflow possible (I’m not aware of this). Alternatively, if you want to make this more accessible, you could make your own extension and distribute it through the Slicer Extension Manager. If you follow this approach, be aware of the changes that are going to be introduced in the Extensions ecosystem (Introduction of "tiers" for Slicer extensions)
