Unfortunately, we have failed to simulate the trouble.
Please take the following steps to make sure whether position of names is saved properly:
Create a new PER model.
Create two entities and connect them via relationship.
Change position of relat. name.
Save the model and close the model.
Open the model.
Is the name in the position where you moved it? Let us know.
If the position was saved properly, please try to remember what exactly you did with your model before you saved it. Thanks for the details.
If you can reproduce the problem on your model (the trouble occurs repeatedly in the model), please send the model to us. We will look at it. You can send it to: modeling@quest.com. Thanks.
