The arrangement of custom properties in the properties list directly influences the sequence in which property fields will appear in the dialog when creating or editing an object. You can rearrange the custom properties to change their order in the Custom properties data grid.
To preview the order of fields in the dialog, select the Preview button 
in the top right corner of the object type line.
This will display a Preview properties window, in which the custom properties are displayed in their existing order.
To rearrange custom properties:
- Locate the desired object type in the data grid.
- Select the Edit property order icon (the pencil icon) in the top right corner of the object type line.
- Drag and drop custom properties to arrange them in the desired order.
- Select Save.
