While combining and merging bodies, often times I have seen that there are visible (unwanted ) join lines in the part. This is the case even if there is no height difference at the area of combine. In other words all surfaces are coincident.

These lines are needless distractors in the part. I usually resort to removal of such lines in the drawing using hide->edge.

The question is, why does these line show. Also, is there a way to hide these lines in part itself?

thanks in advance
