There was I believe something based on using the dimensions of the underlying sketches. Someone else may elucidate further, but I just have to query whether those things ever work? I find it an important part of the design process to dimension in line with design intent and in so doing to think through the manufacturing tolerances etc.
i few years ago i did some machining with NX on some models done on inventor, the drawings used "auto dimensioning" and often the same feature was dimensioned multiple times from rediculous datums, and sizes that were required were missed off all together requiring further analysis and re-drawing, i feel that this was more due to bad modelling and slack drawing techniques, with a belief that it must be OK cos it's automatic??. Even so i feel that this feature was next to useless
I agree with moog. In both NX and SolidWorks I avoid the auto-dimensioning because it just isn't worth the headache - but maybe in a smaller part it will work fine.
I disagee on that. I was working Solidworks for 5 years and changed to NX6 cause of my job. The Auto Dimension feature of Solidworks might not be perfect (like almost every design feature in every design package) but it is still very helpfull.
In small designs i just auto dimesnion and just erase the dimensions i dont like. In a car design might not be helpfull but in small every day designs it rocks.
