To Skew Witness Lines of a Dimension
1. Select one or more dimensions.
2. Right-click outside the model in the graphics window.
3. Click Skew Dimension on the shortcut menu. The skew draggers become available for all selected dimensions. The skew dragger is located at the midpoint of the dimension’s witness lines at some height above the dimension’s text.
4. Drag the skew dragger of the dimension whose witness lines you want to skew. Creo Parametric places the witness lines with an incline according to the movement of the skew dragger. You can skew only one dimension at a time. The skew dragger for that dimension disappears after you finish dragging it. The skew draggers of the other selected dimensions also disappear.
