Hi,I am using AutoCAD 13 Lt & there is times when I insert a multiple different blocks into my Model View and when I change to Layout View & create a view port none of the blocks appear or only 1 doesnt appear. Then I delete that viewport & create another and they all appear perfectly fine.Does anybody know why this is?Thanks

Are some of the layers frozen?Did you freeze layers in a specific viewport?Did you try a zoom > extents while in the viewport?

Are any of these blocks annotative?Dave

The one that disappeared wasn't annotativeClarissa

AutoCAD 2013 is doing some odd things... that's why I haven't adopted it yet.  But if you can repeatedly reproduce this behavior I'd blame it on the program.Dave.
