I'm learning more about sketch blocks and they seems to be something that I was looking for. I have many custom shapes that I use in many parts, but now I'm converting all these shapes to sketch blocks and save to file. Now the problem is, when I insert a sketch block, there is no way of knowing if the block is defined in sketch. Lets say I insert a block, I can drag it around without defining its location by dimension and exit the sketch. The sketch is marked as fully defined, but its not, the sketch block is floating. How do I know which sketch block is floating, because there is no hyper/minus sign in front of it.
