Hi! Opening a dwg file today, I realised after a while that all the gradient values based on the same block are missing from the file, or at least I cannot see them any more. Since it is highly unlikely I have deleted them all one by one by mistake I wonder if anyone knows what might have happened and how they might 're-appear'? The block includes lines to form a symbol as well as changeable text.  I am mainly working in the model through a viewport if that might have an impact. Thank you!

Maybe the layer the blocks were inserted on is turned off or frozen.

Maybe your blocks are "annotative", will not show in viewport (or MS) until you set annotative scale to match blocks.

Thank you for the sugegstions!With all layers visible and not frozen they are still not visible... Today the same happened to all texts. It is a bit confusing!I will try to see if the scales are off, I just don$t know when I would have changed it for it all to become invisible.

Can you attach a copy of the drawing to your next post?
