If one makes a projected view from a parent view and then rotate the parent one gets the options to :

- having the centermarks rotate or not with the view you want to rotate

- have any dependent views update or not to the change in orientation

However, no matter if one chooses to have the dependent views update or not one gets a warning that rotating the (parent) view will affect the dependent views and all dimensions in those dependent views will be lost. And they are.

Why does rotating the parent view have to influence the dimension of the child view? Isn't something that was 100mm long still 10 mm long on a projected view no matter how you rotate the parent view round the axis perpendicular to the view ? 

I could understand if it was concerning ISO, Trimeteric , Dimetric views or any other non-normal projected view but in a normal projected view the distance, measurements, dimensions (whatever you want to call them) stay the same.

Is there a way that I don't know of that one can rotate the parent view and keep the dimensions on the child view ?

Is there a valid explanation for this or is it SW logic?

I for one really don't enjoy put dimensions on a drawing time and time again. The entire advantage of using software to draw is because one has the *aid* of the computer. When the aid becomes a hindrance it's a bit rich to talk about CAD, instead it becomes CSD (computer sabotaged design).
