Bit of trouble with animation on a 18 year old model. Should have fixed 18 years ago but life got in the way.

Don't have the original DST files to fix the model. Need to fix the animation in the S file. I have played with it, but have no clue what I'm doing.

Frank,

Gotta luv those old-timers.

Here is a suggestion for the animation code. Changes are in red.

The animation code tracks the animated piece through a 360 degree cycle. Therefore, the first and last X Y Z steps should be identical. Applies for rotational and linear animations on this model.

If motion is still erratic, the data sets can be graphed as step versus data point on a spreadsheet. This will show any outliers or data points slightly off the curve. New data points can be fitted to the curve.

Keep up the great additions you have done for the train simulation world.


Mike
