revit structure
has anyone here tried to use revit as an analysis tool? i've used it before to do 3-d modeling, but that is the extent of my knowledge of it.

revit doesn't do structural analysis itself - it allows you to build the model in revit and then transfer to a structural software package like risa-3d.
it will also integrate with woodworks.

with woodworks? really? i'd be interested to see how that one works.
clansman: you're right. my mistake.

when the structural model is created in revit, what happens at the nodes? does revit make adjustments to the lengths of the beams to fit outside the column flanges or webs? or is it like staad where the
i think revit has the visible beam entity and it has the theoretical beam "line" - both co-exist within revit.
one is all about the drawing/representation of the beam and the other is the theoretical beam position used by the associated analysis programs.
you can display either, neither or both.
i have not used revit and do not personally know any engineers who have used it. yet. going to check on some seminars.
im using revit structure 2008 right now. i have drawn the structures in revit and then exported them to both ram and etabs. once the analysis is complete, you can reimport the designed sizes back into revit. as said above, revit doesnt do the analysis.
revit automatically produces a setback that can be changed. the node is actually at the workpoint of the connection. when you go to cut the section revit generates the 2d column and a beam. that's it. very bland. so you have to draw in by hand in 2d all the bolts, clip angles, welds, text, everything. and if you update the beam size, your hand drawn stuff doesn't update with it. it sucks. everyone i know hates it. have been to the 3 day training course and even the trainer says they a lot of people are let down when they get into it because a lot of the sales pitches are deceptive. it's so much more work for nothing gained. the company hasn't been profitable on any revit jobs. it doesnt help coordination issues like they claim. beware
but how is that still not better than "drawing by hand" all the autocadd details that don't update anythingfff"> when you change a beam size?
at least with revit, you can model the structure, view it, rotate it, understand it, export it to analysis software, etc.
i'm not arguing with you - just trying to marry your displeasure with what i've seen done elsewhere...
we've been using revit on another segment of our business (precast) and most of the guys are starting to buy into it.
thanks for comments atomic and jae. for the coordination with other consultants like the architect and mep, are you integrating their revit models into yours?
