1. Creating and Importing Alternatives

To create a new alternative, you must first create or load a project. You can then click the

button to open the Alternatives side menu.

From here, you can also switch to alternatives that have already been created (see Figure 1). The alternatives displayed here can be moved and rearranged using drag-and-drop with the mouse.

The following table explains the functions of the buttons in the Alternatives window:

Button	Description
	Opens a new window where you can create a new, empty alternative
	Opens a dialog box that allows you to import alternatives from other projects.
	Opens an information dialog for starting and reviewing simulation runs. For details on simulation runs, see the chapter Start and organize simulation runs
	Displays the status of the simulation run for the active alternative
	Access to the options Edit, Duplicate, Set/Unset as Main Alternative, and Delete

2. Editing Alternatives

To edit an alternative, first select the desired alternative and then click the Edit button in the Options dialog.

Here, you can enter a new name for the alternative and confirm it by clicking the Apply button.

3. Duplicating Alternatives

You can duplicate the current model using the context menu. A “_1” is appended to the name of the original. The duplicate is inserted into the list below the original.

4. Setting Alternatives as a Reference

By clicking Set as Reference, the selected alternative can be designated as the “reference alternative,” which serves as the basis for comparing parameter values.

In the other alternatives, each parameter value is then compared with the corresponding parameter value from the reference alternative.

If at least one parameter of an object has a different value than in the main model, an icon is displayed above the object to indicate the deviation.

In addition, an indicator is displayed in the parameter sidebar for each deviating parameter, and a reset function is provided (see General Settings, Section 5).

Once an alternative has been set as the reference alternative, this is indicated in the sidebar by an icon and a colored background.

The setting can be removed in the same way. Only one alternative per project can be designated as the main alternative at a time.

5. Deleting Alternatives

To delete an alternative, first select the desired alternative and then click the Delete button in the Options dialog.
