Trying to do a simple trial animation just to make a box rotate. Am using the time slider rather than a tour. Obviously doing something wrong because it "swings" around an origin that is a long way from the model rather than rotating on its axis.
I read the bit above about creating it at the origin, not moving the axes, but it still does not seem to help. I am wondering if it could be to do with georeferencing. Here is what I have done, along with numerous other things:
Started Sketchup Drew a box centred on the origin Displayed the model in GE. It appeared somewhere over Sydney, floating about 50m above the ground. Saved the model to KMZ Opened it with Winzip and extracted the KML Duplicated the model placemark 3 times Added the timespan and heading fields to each one Copied the KML back into the KMZ Deleted the old model from temporary places and opened the new one. Clicked the time slider to start.The model rotates around a point that is about 300m from the centre of the box.
I have attached the KMZ.
The next issue once I get that working is how to do the animation with an existing model, where the origin obviously is not at the midpoint of the object that needs to be animated. If one selects the whole model and moves it so that is centred on the origin then the model will no longer be correctly located in GE.
So presumably I copy each piece and paste it into a new model centred on the origin...?
