### Checks related to component pin lead

When component symbols are created, Component Symbol Librarians usually follow some basic rules when creating the symbols for a well-managed ECAD Library. Companies that permit user to create symbols as needs, often find that rules are not completely followed, and issues are found in the assembly phase of the design.Some basic checks should be made available to detect these issues at the design level, and if possible, at the symbol creation level.
Some example of such checks could be, "Through hole lead to drill size", "SMD Lead to SMD pad size", and so on.
Rules for these checks can vary based upon the lead type. For example, the rule for lead to pad could be different for J-LEAD vs Gull-Wing.
