I was able to draw geometry, dimensions and annotations just fine anywhere on my sheet in Layout, including on top of viewports. Now for some reason I cannot, even though it is in the same drawing. The old lines, dimension etc. stay on top, even if I copy them, but anything new I create gets hidden behind the viewports. NOTE: I have tried several times to send the viewports to the back, and send the new dimensions, lines etc. to the front, and this does not solve the problem.
If anyone has any insight as to what the cause of this problem is I would greatly appreciate some advice.
