This is the first I've noticed this, but a sketch in an assembly does not allow to show the dimensions as an expression? In a .ipt sketch you can right click and the pop-up menu has an option to show the dimensions in different forms. I do not get this in an assembly sketch.
I do not know if this is me or not. It's just curious that it does not do that.
As you can see I do not have that Icon. Is there a way to turn it on?
Strange. Try view tab, user interface and uncheck status bar, then turn it back on and see if the icon appears.
Have you loaded update 2?
I looked in Document settings and was going to say, "Why don't you just change it there?" but it didn't seem to have any effect.
Remember, the sketch interface in the assembly environment may look sort of like the sketch interface in the part environment but they are not the same. (I attribute any similarity to the overarching power of the icon team.)
