Hi Nick,

> They *should* have been on the same layer/style...

It looks like they all are - but you can also hide objects not just by using the style controls but also by using the Edit > Hide button.

So for example if you select the top face of a box like this:



If you then go and push the Edit > Hide button, that face will be hidden, and it will look like this:



The face is still there, it's just been marked as hidden so it's not currently being displayed.

The style assignment of that face did not change though, only the hidden property of that face was changed. So now you have some things of that style that are hidden and some things that are shown, the scene browser shows this mixed state by displaying a half eye for the style's status:




This is one of the areas where MoI's styles are a little different than Rhino layers - in MoI when you click on the eye icon for a style, you're actually modifying the hidden property of several objects. That's a little different than Rhino because in Rhino a layer has its very own on/off property.

Working in this way gives MoI a lot of additional flexibility, like having the other "Objects" and "Types" sections in the scene browser that you can use alongside of the Styles section.

For example in MoI it is possible to show all solids by going to the Types section and clicking on the eye icon for the "Solids" item in there. The way Rhino is set up, it's not really feasible to do that very well because in Rhino in order to show an object you have to set the layer that an object is on to be visible and that will end up showing anything else that was also on that layer as well.
