Had a odd thing happen when editing a sketch. File is 2018. Had a point fly way off in space so I zoom/fit found the point and deleted it. So not the file behaves like it is 1 million units large. So not there are all sorts of floating point graphic issues. Is there a way to repair the file? And effectively select anything. Not how text for dimensions are all piled on top of each other. Rebooted computer and the file still shows the problem. Other files are fine.
Notice how the numbers for each dimension are all piled on top of one another. End points are not on end of line and everything is jumpy like there is a floating point issue. In the 5 years of using SolidWorks as an Instructor and working with 1000s of students I have never seen something go this far south.
