Manipulate with Handles has changed in XM.
Element manipulation using handles works differently in XM than in previous versions.Version: 08.09.02.52Product: MicroStation V8 XM EditionArea: Manipulation
Element manipulation and modification using handles has been updated.There are no longer two sets of handles. Now, by default, when you drag a handle to modify an element, the geometric relationships are preserved (angle, radius ratios, and so on). You can toggle this off by pressing the <Alt> key while dragging, which results in the selected vertex only being modified.
