Hi - I currently have 2 separate models that simulate a mfg facility that are in two different locations (US & Sweden). The Swedish plant feeds finished goods to the US, the US plant also products these goods, then kits both US and Swedish goods together. Does anyone have any recommendations as to how I can combine these two models into one???

If you want to make two models to one model,
Some ways will be...
But I found two two ways to solve it...
I hope the more good way to be found.

Way I.
1) Open the model of Swedish.
2) Open one more US plant model (You can run two Flexsim at same time in a PC)
3) Copy one model using ctrl-c and then copy it to another model using ctrl-v.
4) the copied model objects appear as red-color selected.
And then connect two models items flow using virtual distance (or time consuming)

Way II
1) Save Swedish plant model as tree after selecting all objects on model.
View>Edit selected Objects>Save To File button and then
the model is saved to ???.t
close the model and open the other model.
2) Load the saved model in newly open model.
View>Edit selected Objects>Load File button.

3) Maybe the loaded model objects will be appeared as red-color selected.
And then connect two models items flow using virtual distance (or time consuming)
