Thanks for your reply Petr Tulach. I've already emailed you
I would like to add some information that I did not state on the original post. Thus, I would like to emphasize that, to update the layout of a single model, I have to delete all the objects on its Facility and then create them anew. The simple process of deleting all the models can take hours! Sometimes, it takes more time to delete them all than to create a new warehouse (I can't understand this). Thus, I have 2 processes each 1 consuming more that 1 hour!
All of this, just to update the logic of all the other Simio files I have that are using the same logic... Isn't there a better way to do this? So, I really would apretiate some help, even if it is just to tell me that there is no alternative to what im currently doing (at least I would know I have to do it this way, unfortunately)
