Have developed a problem I have not seen before. Elevation hatch does not line up automatically any more. See the attached pic below. The green highlighted element is a slab. Have snapped it directly to the wall below it, and the wall above it is snapped directly to the corner of the slab. Have noticed it in a couple of other drawings also, but have been able to ignore it.
It was created while the accuracy is set is 1/64" inch. Which is another issue within the office. What is the recommended accuracy. One of my techs insists on using that value because he thinks anything less will not enable him to snap directly to points. As he zooms in closer and closer, it appears elements are not really snapped to points, even though the check mark appears while snapping. I wonder if the two issues are related somehow.
