Go to the same menu, see a different dialog

Here is an example. In a 2D system, choose Model | add a new model, you will see a dialog box. This dialog will show different information, which sensitive to number of model and parametric difference.

If it is the first time, you will see a dialog which tell you “there is no any additional model”

After you add one, it tells you there is one and displays parametric difference if there are some, provides more choice to show where is the model.

Every time when you do adding, or modify the parameters, you will see a different report, which collects information you have modified.


Here is another example. Assume that you want to get a rectangle area. If you have a clicked on the 2D viewer, The dialog will be center-extended;

but if you drag an area, the dialog will be two-point format.
