Hello. I want to change the center of rotation of a 3d model(stl). I would like to rotate it in his own center of rotation (In the middle of the object). Because now I only can rotate it with a rotation around the 0.0 ax. Thanks for your answers and help

There is a recipe for this in the script repository https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html#rotate-a-node-around-a-specified-point

:grinning: learned a ton, very useful to me.

Sorry I don’t understand the process.Shall I paste the script somewhere (in the code section?) I can’t rotate around a center of rotation I’d like to choose. thanks

Yes, you can paste the code in the Python console (which can be opened/hidden by pressing Ctrl-3). This area is a command prompt for an interactive python session in Slicer’s python environment. Many scripts in the script repository will work without modification when pasted directly to the python…

thanks so much but a video would be great . I know we are all busy. Best regards

FYI, @Sunderlandkyl is working on a new transform widget that will allow rotation around a chosen point (and translation along object or world axes) in both 2D and 3D views. The first version of the feature may be available in the Slicer Preview Release within a couple of weeks. You can track the p…

In current Slicer Preview Release you can set the center of rotation for the transformation. Visually in a 2D/3D editor, or as center of a node, or by entering coordinates in the Transforms module, or using Python scripting setting the center in the transform node.
