If sketch lines are oriented horizontally or vertically, when dimensions are applied to them, that dimensions are also will be horizontal or vertical. So, if I rotate the sketch profile, all such dimensions become wrong. And I have to delete them and reapply aligned dimeansions manually to restore correct shape.
I suggest to add ability to manually change alignment attributes for dimension lines. For example, add corresponding context menu (like it's done for "Toggle Driven"):
Also, it would be great to have "Default Dimensions Alignment" settings somewhere in Preferences. Where I could choose between "Horizontal / Vertical" (parallel to axis, as it behaves currently) and "Aligned" (parallel to line, as I would like to see).
