1. A method implemented by one or more content servers, the method comprising:

obtaining, by one or more processors of the one or more content servers, a first parametric model of a first part, the first

parametric model conforming to a first parametric modeling framework, and the first parametric model comprising a plurality

of first parameters and one or more first constraints between pairs of the first parameters;

generating, by one or more processors of the one or more content servers, a first part family representation from the first

parametric model of the first part, the first part family representation including a plurality of parts each having a same

shape and a different respective size, for each part in the first part family representation, wherein the generated first

part family representation is in a parametric model-independent format, which does not include a parametric model with parameters

and constraints between pairs of parameters;

importing, by one or more processors of the one or more content servers, a second parametric model of a second part, the second

parametric model conforming to a second parametric modeling framework, which is different than the first parametric modelling

framework, and the second parametric model comprising a plurality of second parameters and one or more second constraints

between pairs of the second parameters;

generating, by one or more processors of the one or more content servers, a second part family representation from the second

parametric model of the second part, the second part family representation including a plurality of parts each having a same

shape and a different respective size, for each part in the second part family representation, wherein the generated second

part family representation is in the parametric model-independent format, which does not include a parametric model with parameters

and constraints between pairs of parameters;

making, by one or more processors of the one or more content servers, both the first part family representation in the parametric

model-independent format and the second part family representation in the parametric model-independent format available to

a client device having a particular computer-aided design system;

receiving, by one or more processors of the one or more content servers, a first request from the client device for the first

part family;

converting, by one or more processors of the one or more content servers, the first part family to a format that is compatible

with the particular computer-aided design system of the client device;

providing, by one or more processors of the one or more content servers, the converted first part family to the client device

in response to the first request;

receiving, by one or more processors of the one or more content servers, a second request from the client device for the second

part family;

converting, by one or more processors of the one or more content servers, the second part family to the format that is compatible

with the particular computer-aided design system of the client device; and

providing, by one or more processors of the one or more content servers, the converted second part family to the client device

in response to the second request;

wherein generating the second part family representation from the second parametric model of the second part comprises mapping

properties of the second parametric modeling framework to properties of the first parametric modeling framework, and creating

the second part family representation of the second part using the first parametric modelling framework in accordance with

the mapped properties;

wherein each of the first part family representation and the second part family representation is a fixed-size representation

comprising fixed-size solid objects and non-graphical family data; and

wherein each fixed-size representation of a part family further comprises a static graphic representation showing connection

port locations for the part family.
