Have you ever tried using animation software? I have. It inevitably leads to hospitalisation after a severe nervous breakdown. However, Jim's SketchUp (Plugins) Blog can save you thousands in counselling and even medication. (only kidding!) His animation plugin is so easy to install and use.
If you like Jim's stuff, don't forget to give him a few bucks! Paypal button is on his blog.
A lighthearted blog about SketchUp and the non-profit "DesignerDojo" Initiative whose mission is to teach kids SketchUp and 3D modeling for free. Sponsored by Viewsion- Ireland's Trimble SketchUp Authorised Training Centre.
