Parametric Parts
The Parametric Parts of IronCAD Mechanical have been developed taking into consideration the needs of mechanical engineers. In other words, all the settings, and commands have been studied with care, and all of the components have an internal intelligence that allows the user to become faster and more productive.
For example, if a nut were to be placed on a screw, it will automatically inherit the dimension value; you can resize the screw without user interference.
For a detailed explanation see Fasteners and Fasteners Assembly
Also, if you place an Oring or Seeger on a shaft, the component can automatically create the shaft groove using the correct built-in parameters.
