Preferences (menu) -> Annotation (menu item) -> Ordinate (tab) --> on this tab, change "dogleg" to "infer" and it will USUALLY insert a dogleg when appropriate. If it does not - you can select the specific dimension you want to change. You can then open the 'style' of any specific dimension and change the ordinate properties so that "dogleg" is set to "yes".
Also - this is unrelated to ordinate dimensions, but - you can change the style of the view so that "smooth edges" are off. You can turn on "visual intersections" if necessary. This will greatly reduce the clutter of complicated views such as you have in your screenshot... unless those smooth edges are intentionally desired.
