Hi everyone,  
I have spotted a strange behavior of models with slice display in projection mode. (Slicer 11)  
If you look at the yellow slice scene you should not see the model as it is out of range. This is well displayed for other scenes.  
If I have time I will look into it but people with more experience will solve to problem way faster than me.

Cheers,  
Pierre

This looks correct. Simple “Projection” mode shows the model in the current slice:

In most cases you want to use “Intersection” mode instead:

In case you want to show the whole model or a thick slice of the model in the slice view then use “Distance encoded projection” mode:

You get a number of additional slice view display options if you convert the model to segmentation node.
