Sorry, not exactly sure where to ask this, but we have a drawing of a boat and it has bulkheads in it that look like this:
And when we do certain things (for instance, if we draw a shape and try to extrude it), all the bulkheads turn to this:
This even happens if the sketched part is not touching/merging with any other part on the boat. This was also happening the other day when I would measure a bulkhead and then go to measure the next bulkhead everything would convert to these squares/rectangles. There are also no notifications when this happens, it just happens, and there is no undo option for it.
Is there a reason why this is happening or something we should be doing differently? Or there a way to revert them back to their 'bulkhead' shape?
Thanks in advance!
EDIT: Sorry, I guess there are errors to do with surfacing/sketches. File is attached.
