Hello,  
Consider a segmentation that has multiple parts. Is it possible to magnify one or two of these parts by a specific factor (1.1, 1.2, etc.)? If yes, what is the command for it?  
Any help is greatly appreciated.

You can apply a transform to a segmentation node, not to individual segments. So, if you only want to scale selected segments then you can temporarily move them out to a separate segmentation, apply a transform to that, and then move those back to the original segmentation.

Alternatively, you can simply grow a segment in a segmentation by using Margin effect.
