Does 3D slicer have any tools with a function similar to AMIRA's "magic wand"?

I’m looking for a 3D Slicer tool that will segment a bone isolated from others from a single click, taking into account the threshold chosen by the user. This logic of this tool would be to select all the pixels that are in contact with the spot where the cick was made (in sequence), within the chosen threshold.
This is how AMIRA’s “Magic Wand” works.
Does 3D slicer have any tools with a function similar to AMIRA’s “Magic Wand”?

The properties of the computer I’m using for segmentating are as follows:

gpu - Nvidia Quadro P4000
256 GB RAM
Processor: Xeon E5-2643 v4 – 3,4 GHz (6 cores)

Yes, and also hopefully you find there are also much better tools.

I think the closest to the Magic Wand effect is “Flood filling” effect, provided by SegmentEditorExtraEffects extension.

I would also recommend to try “Grow from seeds” effect as explained here: Bone segmentation to create 3D-printable STL. You may also try to use Watershed effect, which takes some more time to compute but provides smooth surfaces.

I would also recommend to check out segmentation tutorials here: https://www.slicer.org/wiki/Documentation/Nightly/Training#Slicer4_Image_Segmentation

It has been a while I used Amira but, isn’t the “level trace” + intensity range is a closer approximation of the magic wand?
