For the initial video in this thread, I’m really curious why the bounding box is taller than the selected dimension lines. I think that’s why the double arrow move icon was not showing up on the dimension edge. Moving the mouse up slightly next to that blue triangle arrow under the 2 would theoretically have triggered the double arrow icon. When multiple dimensions are selected, that double arrow icon shows up at the edge of the total selection, not necessarily on the edge of the dimension line.
The red spray paint line in this image indicates the top selection boundary edge.
So I’m not sure why that was happening with that, @Odd_Haakon_Byberg.
Notice the double-arrow icon shows up even over empty space, as long as it’s lined up with the boundary of the selection:
That selection boundary rule explains why the double arrow icon does not show up when hovering over this dimension edge that is inside of the selection boundary:
