A parametric part is the encapsulation of all the details needed by AutoTRAX DEX to generate the schematics symbols, footprint and 3D solid model for a real part.

Parametric parts are extremely powerful. From only a small collection of numerical values parametric parts can generate complex graphics including 2-D graphics and 3-D graphics.

To illustrate the concept let's consider a PIC10F200 micro-controller from Microchip.

We will consider the version that comes in an 8-pin PDIP package.

There are 3 parts to consider.

1.The Manufacturer's model and specification of the device.

2.What you actually get.

3.The model used by AutoTRAX DEX to help you incorporate it into the system you are designing.
