Can I check if a edge or vertex is show in swModelView

Hi Everybody,

Can I check if a edge or vertex is show in swModelView?Which SW or orther program API can support it ?

I don't mean the edge's(or vertex ) visible property.

For example ,when a vertex's visible is true .But when it cover by a surface in swModelView ,it can not show to my eye(except the surface is transpacent).

thank you
