Questions in Grids, Guides and Views

• Inserting Objects - I am using Design 3D on my iMac with Tiger. I can only insert shapes, light sources in top/plan view, and not in any other view. Can you explain why?

• Moving Objects - This maybe a simple question, but when using the Point Light Tool the bulb sticks to the grid and will not move vertically.

• Auto Grid - In the Edit Menu > Active Grid, can grids be made active at all times? I want to switch between views without having to change the grid each time.

• Active Grid - How can I set it up so that the current view I'm viewing is always the active grid?
