Ive noticed when i click on a Dim to change the length or location of something, it asks me for a number OR a formula starting with = . Ive checked the tutorial and a Revit book published by someone else, and i cannot find a list of any of these formulas, which i think may be what im looking for to answer a few questions i have. Anyone know where to find them?

Okay, sorry for the noob post... One quick google came up with more than i thought it would...
Still looking to see whats out there though, i found formulae based on arithmatic functions (+, -, sin, cos, etc.) but i am still wondering about formulas available to relate one wall to another, etc.
It may not exist, and thats cool. Im just looking for a comparison between Catia and Revit. Catia can do it, but at the very high expense of a rediculous interface that is easy to use once you know it, but not worth the effort (for architecture, anyway, imho) to teach people. This is the last function ive been looking for that Catia can do that Revit cannot, aside from the Tree functions being very different...

At this point, im looking for the different limitations to the formulas, simply to know what i can and cannot do with Revit. I see that with formulas, you can make things dependant on angles and measurements... Im just not sure if these measurements just be within the same object or family (Length, Width...)
If i have two walls meeting at a particular angle, for example, and that angle is a function of one walls length, how would one set such a formula up?
