euqal lentgh\radius versus linked dimension

linking is for relating dimensions across different sketches, features. equal length works in the same sketch.

Also, linking may be a clearer way of representing that two things are the same. Especially when dimension names are turned on.

Also, if you have say 8-10 dimensions that you always want to be the same, it would take 8-10 equations to achieve the same thing as simply linking them.

One way they could be utilized is for like adding general fillets or chamfers to a part. It may take multiple features to put all of the fillets/chamfers on the part, but you want them to always be the same. If you link them, any change to any one of the features will update all of the fillet/chamfer features.

If you need to control the length of an arc to equal the length of a straight line, linking works great. (I did this to develop points for an involute once.)

Also works for controlling other dissimilar parameters, i.e. bend radii and thickness; extrusion length and sketch entity dimension.

Thanks, i think you made an important point that i totaly missed!

thanks guy's. your arguments about the visibilety of dimesions versus relations, is a good one, although i think that "That70sTick" has the most convincing of all.
