## What is Engineering Tolerance?

Calculate or learn all kind of engineering tolerances in whole wide range from A to ZC (for holes) and from a to zc (for shafts) in twenty IT grades (01, 0, 1 - 18). It is possible to define nominal diameter from 0 to 500 (mm). You can choose your considered tolerances interactive way by selecting them from main view. Whole geometry is finaly shown with all dimmensions and with calculated values. You can modify all parameters and you obtain immediate response, redraw and recalculation engineering tolerances for better design of components used in industry.

Features:
--- All tolerances (A-ZC and a-zc)
--- Twenty IT grades (01, 0, 1 - 18)
--- Diameter range (0 - 500)(mm)
--- All type of Fits (Clearance, Transition and Interference)
--- Hide / Show Dimmensions

This application will show you that learning can be very fun!
Good luck and success !
