[max77]

Hi,
i have many .mi files and inside each .mi files there is a tool.
usually every tools is very similar to each other.
so in the future i would like to query a database giving him the characteristic
of the tool that i need so that the database finds out the closest tool (that i've already designed in the past)
to the one that i need and that designer drafting load automatically this tool in the current opened window.
is it possible?
what are the best program that could help me?
what do you suggest?

thank you!!!!!!!
