Thank you for your quick reply.
I managed to make some it work with the tweens, but I have trouble with a section plane?
My movie consits of both a section plane (a slab appearing) and a movement (coloumns put in place), but I can only animate the movement and not the slab appearing. All I get is a still picture of the section plane indicators with the slab in the first part of the movie, and then a rotation in the end of the movie.
If I use the built-in animation I get the reverse problem - A slab appearing, but no movement.
I have a presentation in a week and I would hate not to get the full animation.
Am I doing something wrong or is there a work-around?
Thank you for your help!
