Opening an existing model

When you already have a model or models that you are working on, there are several ways to open them. You can have more than one model open at the same time.

To open an existing model:

Do one of the following:

Select File and then, if your model is in the recent file list, select the appropriate model.

or
Select File > Open, browse to the appropriate model (‘lgm’) file and click the Open button.

or
Open the file in Windows Explorer or from your Desktop.

Your model opens in LEGION Model Builder workspace.
If the model was created in a previous version of the software, you will be prompted to upgrade the model. Click Yes to upgrade. To retain the upgraded features, make sure you save the model.
