Hi Val,

> Also, is there a way to select objects inside objects,

Yup, just doing the regular drag to make a selection rectangle will work for that, see this recent thread for some details:

There's a couple of different things you can do - if you go to the View Palette, there's a checkbox there for "Display hidden lines", which you can enable if you want to see hidden curves and edges in a faint dashed line style. That makes it easy to select hidden curves and edges as if they were in a kind of wireframe mode.

You can also hide face sub-objects if you want, just select them and push the hide button. You can also hide all faces quickly by using the scene browser Types section, click the eye icon next to "Faces", and that will hide all faces leaving only wire objects being shown.
