put the pictures on a separte layer and look that layer ?
in the preferences (modelling aids ?) there should be an option wether to not snap (default i think) or snap to locked items…
sorry - i do not have a v5 windows version running …
that will do it but it also snaps to surfaces when I am above them performingg drawing etc, and I dont want my objects on different layers from where they should be so as to lock them, if I lock their existing layer I forget and a while later having moved things about, they are not where they now should be. Thats a bad one.
I would be far happier to just deny snap to surface as an osnap.
Rhino doesn’t actually snap to surfaces when you are drawing, right? It might snap to near, etc, but the real problem I think you are describing is that when you want to edit a drawing, you are constantly asked if you want to pick the surface or the point/line/whatever. If that’s the case, then the solution is to put it on a sublayer and lock it. You should not misplace a sublayer, right?
Another solution is to use selection filters, but I don’t think those existed in V5.
