What happens to the Model:
Once a Model is Ungrouped it no longer has the same characteristics/attributes of the Model tool that created it. In other words, Ungrouping a Model changes it to a drawing. A warning message will appear stating, "Once ungrouped, you will not be able to edit the Model using Model Tools and commands. Continue?". In the case of the Models that cannot be Ungrouped easily, the menu choices Ungroup and Group are grayed out.
How to Ungroup other Model Types:
You can ungroup a Data Chart if you first separate the data table using the Separate Table command from the Chart menu (the Separate Table command will only be available when a Data Chart Model is selected with the gray border). When separating a message will appear stating, "Separating the Table from the Chart will make the Chart values only modifiable from the Table. Continue?". Once separated you will need to cut and paste the Chart so that it can then be Ungrouped. If you do not cut and paste the chart, Ungroup will remain grayed out. If your Data Chart has been created from a Table using the Make Chart Command under the Table menu then you will not need to Separate the Table since it already is separated. Simply cut, paste and then Ungroup.
If you wish to Ungroup a Table or Timeline Model you will need to paste the Model into the Scrapbook temporarily. In order to paste a Model into the Scrapbook you will need to first select it with just the black selection handles. Once this is done, cut and then paste the Model into the Scrapbook. Now that your Model is in the Scrapbook, cut it from the Scrapbook and paste it into your ClarisImpact document. Now you will be able to Ungroup it. This method can also be used with a Word Processing or Outline Model but since there is only text in one of these Models and mostly text in the other it will not be helpful to Ungroup these two types of Models.
Warning:
Make a back-up of your Model in case you make a mistake or decide you need to modify the Model with the Model tools again. In other words, once a Model is Ungrouped it will remain a drawing forever.
