I imported a 3D model to Creo Illustrate through Import>Link. I created sequences by moving different parts of the model in each step. I then edited the model in Parametric and removed some details that were transformed in the sequences I made in Creo Illustrate. After that I Re-opened the c3di file which contains the sequence, the model was updated to the model I saved in parametric after editing. Now the steps containing the sequences of the details that i removed from the model are still there and can be played even though the parts are missing. In short: sequences of removed parts are still there and require time to be played even though they are not visible. Sequences to parts that are no longer inside the SBom should automatically be removed or surpressed, that would make much more sense.
As of now I am required to delete the sequences for parts that are deleted which is almost impossible due to the complexity of the illustration with overlapping sequences.
