Hi all I really like archicad but every time see some Image of revit 2011 ask my self if that time to move to revit I hope that not come ever .but ac 14 shock me I hope AC 15 have free model ,spilt face ,good sun study ,good stair maker,new interface,pattern ,sweep,smooth roof , and more.
every time I hear some move to revit and never hear some one move form revit to AC I hope hear that
thank you.

This is a great thread. I wonder if we could could take a poll from experienced users of both programs, to see what they prefer. Somehow it would need to remain objective.

There is a published full blown BIM Evaluation report (for a fee) by Lachmi Khemlani at http://www.aecbytes.com/report/index.html

It would be nice to produce a free or cheaper report of our own...

I've seen this report mentioned before, but no one has ever commented on its content. At those high prices, i wonder how many have been sold.

It's great to hear from you Scott
THAT would be a report I would gladly pay for

Very biased to say the least.

Your comments on relationships is 99% of the the users choice, either you want them or not. Your conclusion casts light on the validity of all your other comments.

How many addons do you pay for in Archicad to get the job done Ransom?
Not to be a pedantic ninny, and correct me if I'm wrong but isn't a "comparison" basically just a list of differences of one object COMPARED to another object......as you so aptly put it in the second part of that sentence?

And of course there's bound to be some level and degree of bias.
Especially in a situation like this where the person doing the comparison has more experience in one software over the other (something that's rather inevitable given the fact that ArchiCAD has existed for far longer than Revit has and most likely people who are proficient enough in both software to do a reasonable comparison, are also likely to have used ArchiCAD for far longer than Revit has even existed.) It would be somewhat silly not to expect any level of bias at all.

Just because there's bias, it doesn't invalidate teh comparison at all.
Everybody comes from a specific point of view from which they frame their perspectives and opinions.
Even Lachmi Khemlami who does her various reviews of the BIM products for AECbytes mag, is never capable of fully hiding the fact that she comes from an Autodesk background and that this thus colours her opinions in a certain specific light.

That being said, the issue of relationships and constraints in BIM software is indeed quite subjective and often down to the users' preference.
I think most ArchiCAD users accept the logic and thinking that Graphisoft's decision not to go full-on with parametric constraints and relationships between elements is a good thing because a) it allows the user to maintain complete control and awareness of what's happening in their project (even at the cost of automation which may or may not be a good thing ..or bad) and b) it allows the program itself to keep running smoothly, and relatively faster (for similar project sizes) than Revit and to not get bogged down by over-constraining as so often happens with Revit.

How any of this - or the rest of the stuff in that list casts any doubt on the validity of his other comments is beyond me.

I'm a bit late to this discussion, so some of these points may have already been addressed in the subsequent comments, but it's useful to point out that a similar discussion - which some of you are already aware of - of REvit versus ArchiCAD is taking place in the ArchiCAD LinkedIn groupit it provides some equally enlightening insights and points.

.......
That's highly unlikely to happen. The "remain objective" part, that is.

Somehow I suspect that the people with more experience in ArchiCAD will have a stronger preference and bias toward it, which those with more experience in Revit will have a stronger prediliction for it, in such a comparison.


(plus, I once read somewhere that it's virtually impossible for human beings to remain completely objective on any matter even on those that they have very little information about. But that's neither here nor there.)



First time users will understandably have a hard time deciding either way, and are also likely to be influenced by whatever 2D Flatland CAD background they came from before jumping to BIM and also whatever corporate (their bosses) or marketing influence (also known as Autodesk, here in North America) they are under...... or not.

There's also the issue that despite the fact that both programs perform a similar function (Building Design, Construction Documentation Information coordination and management), they do it in such differing ways and contrasting styles in some respects that it's almost impossible to like both of them equally (or hate them equally) and it could even be considered to be something of a Rorschach test* as to why certain people gravitate towards one program over the other in terms of its specific workflow, interface, methodology and their own specific mindset.

The most objective and reliable test or comparison that one can ever get of the 2 programs would be to sit down with both of them yourself and try doing a series of functions and commands in both and see which you prefer. You will automatically find that you definitely prefer one over the other.

I'm a long time ArchicAD user (since the late 90's) and recently I've been forced by circumstances to head over to the dark side (again) and have to use Revit, and only now am I truly appreciating just how vastly superior ArchiCAD is to Revit - even with all the warts and all, and all the things we tend to complain about ArchiCAD on this forum.
I mean, if you thought the stair tool in ArchiCAD was bad (and it is in many respects) then you haven't used Revit and been forced to design a and modify and stair with it yet. It's that bad.

As much as I personally tend to be on their case on these forums,( a lot!), even I have to admit that Graphisoft have gotten so very many things correct with ArchiCAD that the Revit folks simply do not get and can't get while they are operating under the corporate structure of Adesk.






(*Rorscharch test - a kind of personality test that tells us more about the person taking the test than the actual test itself. Those ink-blot diagrams which psychiatrists use to test people's personalities based on what the people intepret them to be and which tell the psychiatrists more about the person intpreting the diagram rather than they do tell us anything about the ink-blot diagram itself.
In the same way, a person's choice between REvit and ArchiCAD tells us more about that person's personality, work habits, work ethic, creative preferences and even a little bit about their psychology, than it tells us anything about whether or not one program is superior to the other in any one particular respect or even in an overall general sense. This is because the programs are so different in how they go about doing simple tasks ( - as different from each other as those ink-blots diagrams are from each other -) that it essentially filters out any capacity for objectivity in making a decision between the 2 and boils the decision down to a subjective, personal preference that's framed in how a person thinks rather than how best they work.
At least that's my theory.)

My hunch is that an objective review by experience BIM managers would put ArchiCAD on top.

If Revit did not get the push it got from the Autodesk marketing juggernaut in the USA & Canada, and both programs were marketed equally, I wonder if sales and use would be much different than it is now. I think it would.

When I was a CAD manager at HOK (2000-2005), their CEO wanted to go with ArchiCAD. We knew about Revit and nothing about ArchiCAD at the time, so the general consensus was that we should go with Revit, without any kind of an objective review between the two.

As it turned out, I went to a firm in which an objective review was made, and they went with ArchiCAD. They were gobbled up by HDR who is a Revit firm, after I left. Doh!

I believe the firm that chooses to actively use more than one BIM program is the smarter firm.

Even beyond BIM managers, I believe that if an "objective" assessment (as objective as it possibly could be) had to be made by the people who would actually use the program day-in and day-out - whether you refer to them as the designers, CAD-Monkeys, BIM-Monkeys or what have you - that ArchiCAD would also come out on top,

I recently had an experience at the firm where I work (which is primarily Revit based) when one of the new designers, lady from Brazil who had never used BIM software (Revit or ArchiCAD) before and had been learning Revit in the process of getting going in the firm, passed by my desk where I was modeling a project on my laptop in ArchiCAD in the 3D window.
Now her background was primarily and strictly 2D Flatland CAD or more specifically AutoCAD and she said that BIM in general had hardly had any proliferation where she came from in Brazil, so for her Revit seemed to be the best thing since sliced bread, espeially with everything from automatic generation and updating of sections, elevations and all plans from a single model.
That is, until she saw ArchiCAD in action in the 3D window and asked me who to do that in REvit. I told her that you can't, since Revit's ability to work in 3D is severly hampered by everything from the inability to work or model in perspective view, to the buggy and slow 3D engine which begins to choke up as the model gets heavier and just the general limited functionality of modeling actions in the 3D window with Revit's text-based and dialog-box based interface.
Her comment then was that watching me work in ArchiCAD was like watching someone work in Sketchup - or as close to it as you could get with a BIM program. In other words, while she was mainly "documenting" in Revit, I was actually designing in ArchiCAD, as per her past experience where she was accustomed to doing most of the design-work in a 3D visual environment like Sketchup, and then the documentation in a numerical precision software like AutoCAD.

Hers was the opinion of someone who'd mostly never had any BIM experience at all except for what she had picked up at the office in learning REvit prior to seeing ArchiCAD in action and it was as objective as you could possibly get, but at least informed by a conventional architectural background, education and training. And for her there simply was no contest as to which software she would choose to work in if she had to make the choice herself.

She downloaded an ArchiCAD demo shortly after that.


I guess my point is a large part of the reason why Revit has proliferated an dominated the North American market so much is that in a lot of firms, the decision as to what software or platform to use is typically made by people who will either hardly ever use the software in questions and are primarily interested in saving money (i.e. the owners, principals or senior partners and associates who hardly ever do any digital design grunt work) or by people who while they might use it more frequently than the owners, are likely to be more interested in managing design teams, CAD standards and library databses - in other words, BIM and CAD managers or rather the former CAD (AutoCAD) Managers of the firm),
The people who actually do the design and documentation and modeling and who are the ones that will use the software day in and day out, hardly ever have a say in the matter or the chooice as to which software the firm uses.

Multiply this by a factor of a couple of thousand times exercabated by Autodesk's relentless marketing people (who are hardly design gurus themselves and more marketing and PR people) and strategy, and you have almost total market dominance after a few short years.

I missed Ransom's analysis of sorts of Revit vs ArchiCAD and wanted to clear up a few of the points he made, and back some of the others. Sorry to be late to the party!

I've attached that same PDF with comments.

I find it amusing that a European software platform could play better at NCS than Revit, developed in the USA 😛

I have read Wes comments, and I would take issue, or rather only remark on the very first one where he seems to question the disparity of experience had by Ransom in the 2 software (15 years in ArchiCAD and 3 in Revit) as somewhat affecting the credibility of that comparison.
Especially when he knows the fact that ArchiCAD has existed as a software for far longer than Revit has and that it is virtually impossible for someone who started using ArchiCAD in 1995 (or earlier) to have the same experience in length of time in using Revit (which didn't really exist then nor for some time after that) upon which to base a fair comparison.

Unless he stopped using ArchiCAD sometime after that and began using Revit for the rest of the way where one could say that they've spent virtually equal amounts of time in both software. But even that wouldn't be a fair comparison since one would basically be comparing the most recent version of Revit to a version of ArchiCAD they stopped using a decade ago.


My point about Ransom's comments on the constraints in Revit casting any doubt on the validity of the rest of his comments and conclusions as you suggested was based on the fact that I read those particular comments (on 'constraints' or lack thereof) as his subjective 'opinions'.
As you know, opinions are neither true, nor untrue; they merely reflect the person's subjective feelings on the topic at hand - which is why I said it would not be surprising that ArchiCAD users prefer not to have that much automatic 'constraining' in ArchiCAD as Revit has since that boils that down to personal choice in how one chooses to work rather than an objective assessment of the software itself.

Besides which, on one of his comments Wes himself pretty much agreed with the overall point that the constraining and relationships in Revit can be a bit too tight and that the program would likely benefit, - performance-wise - from the loosening of them - which is essentially the same point that Ransom was making.
