I have been modeling some tools for my company for a few months. Some of the models I made back in July have lost a few or all dimensions in sketch. I had the sketch fully defined and saved; I am the only one who would've even opened the part file. I was wondering if someone could tell me why my fully defined sketch is no longer fully defined. Thanks in advance.
This is a pictured of what one of the sketches looks like now:
Some don't even have that .25 on the end.
