I have a recurrent problem with blocks. In certain blocks if I’m editing it I can see all the elements that compose it, but when I finish editing and go back to the general model, some lines disappear in the viewport; they are not deleted, because they appear again if I make double click over the block and edit it again. In order to solve it I need to erase the “ghost-objects” and create them again.
Pictures: editing the block, not editing the block, not editing the block with the block selected.
I could send the 3dm if needed.
Thanks in advance.
