Change Element Type Wizard
The wizard for changing the element type takes you through the steps for converting a selected element into an element of another type.
Purpose
The Change Element Type wizard takes you through the steps needed to change the type.
The templates required for converting the element type need to exist.
The wizard is only available for elements with certain element types. It does not methodically make sense to have general conversion options in all other element types.
At the top you can see which step you are currently in; from the second step onwards there is also back button 
here, which you can click on to go back a step.
The middle shows the selection options and then the settings.
The bottom contains the Next or Finish buttons and always Abort.
Step 1 of 2: Select template
Select the new element type for the selected element from the Which type should the elements be transformed into? list.
Click on Next.
Step 2 of 2: Ready to transform
The Change Element Type wizard shows a summary of the decisions you have made before converting the type and the consequences of your choices.
You can change these decisions made by pressing the back button to return to the previous steps.
Type conversion may cause irrevocable changes in the model. Please check the consequences of this type conversion very carefully.
Start type conversion by clicking on Finish.
