Problem with Not to scale Details
I have started looking at the CAD details concerning how the window interfaces with framing and weather barrier.
I downloaded the head sill and jamb details for windows used with siding.
I put them together in a composite drawing(head/jamb/sill) and noticed that the materials and components do not “line-up”.
I understand that the drawings are “not to scale” probably in order to exagerate the flashing layers.
Maybe what is needed is one drawing that is to scale and another that illustrates an exploded view to illustrate the layering.
I think that if you were to draw the head detail(mentioned above) to scale..then it might reveal a potential design flaw.
It might also be useful to group the head/jamb/sill details in a composite drawing just to verify that the layers do line-up.
One more thought would be to show an outside elevation view of the window and indicate where the drainage weep holes/channels occur. There is a good chance that a painter or future homeowner will do you a favor and block the drainage path.
