Hi all,

I've been doing some reading/research which made me decide to ask you all the question that heads the thread.

Please don't go and use google, Wikipedia and the likes for generic answers, I'm actually interested in what your honest and at the moment understanding of "Parametric" is.

Dave.

I define parametric as the dynamic relationship between the part's definition of its geometry with its surroundings (constraints) and dimensions such that if the surrounding geometry or the part's dimensions change then the particular geometry updates accordingly. ACAD is not parametric by my definition. A part with a hole diameter that is constrained to be in the center of the part or that is setup to have a diameter one-third of the part width is parametric since changing the part affects the hole per the design intent. Parametric is the key enabler of Design Intent in my book.
