I have created a viewpoint animation and all looks good when I view the animation in Navisworks Manage 2009. I wanted to export to .avi format for presentation. I think I am following the instructions correctly when I go file, export, animation, I select current animation as the source (I have that selected in viewpoints), I select presenter for renderer(or open GL with same result), and the output as windows avi. When I hit save there is about 30 seconds where there is a window showing Preprocessing...., then nothing. If I go to the saved file there is a small .avi (101 KB) and it just shows the first frame sputtering. It never recorded the animation. Any ideas to get this exported effectively are appreciated. Presentation is Monday.
