I want to realize the function that clicking on a model can locate the corresponding item. The current problem is that I can’t seem to select a model, and when the model is selected, how can I know which model is selected. Thanks.

If you mean clicking on the slice views or 3D views and selecting the picked model or segmentation, I heard recently that @Sunderlandkyl may have an implementation in the works. I’m not sure when it will be available.

Ok, I see. So currently slicer doesn’t have a way to select models by clicking on them. Thanks for your answer

Right now the easiest way to achieve this is to click to place a markup point to get a 3D position, and then use the [model displayable manager](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html#get-displayable-manager-of-a-certain-type-for-a-certain-view) to get the model node that is visible at that position using its `Pick3D` and `GetPickedNodeID` methods.

Thanks for the help. I’ll give it a try
