Why ArchiCAD instead of Revit (was ADT)?

Hope you don't mind a newbie question I began a thread over at the construction documentation forum about generating material take-offs in ArchiCad. My question evolved into a more general question of why should I switch from ADT to ArchiCad. Karl suggested this is a more appropriate forum for that question, so here it is. I welcome all responses.

Here is my background info. I am a designer in a small residential (mostly remodeling) design/build firm. I currently use SketchUp for preliminary 3D design and ADT for design development and construction docs. I do not produce material lists or take-offs. Once construction docs are done, the general contractor does material take-offs, builds the project on paper and creates his bid. I like the wall, door, window tools of ADT, but I still really use it as a 2D drafting program. All of my framing plans, sections, foundation, etc., are simply made up of 2D lines. I've never found ADT to be useful as a 3D design/modeling tool. The interface is just too cumbersome. I would be willing to switch over to ArchiCad if there were enough compelling reasons. I know the shortcomings of ADT and I like what I've seen so far of ArchiCad, but I'd like to hear everyone's own opinion and experiences using ArchiCad in a real world situation. Particularly when it comes to creating construction docs. Thanks in advance and Happy Thanksgiving!

{edit}

I suppose I should also include Revit in this question. Why choose ArchiCad over Revit? I am looking for serious pros and cons here so I can make an informed decision. Thanks.

Thanks for your response, but I edited my question and subject of this thread to a Revit comparison. I've been using ADT for several years. I quickly came to realize that ADT is really just a glorified 2D CAD program. It's nice to be able to draw walls, doors, windows as objects but that's about all I use it for. I still produce CD's with 2D lines. I am fully aware of the shortcomings of ADT. And I LOVE SketchUp as a design tool, however it is not a CAD program. The real question is ArchiCad vs. Revit.

Having used Revit through V5 alongside Archicad for several projects: an 18000 SF remodel and addition to a casegoods manufacturing plant and a 16000 SF 2 story office building anlong with a small church and three custom residences, I can attest to the ability of Archicad to complete the work and the inability for Revit to effectively do the same. I had to let my Revit license expire last December as the cost was getting prohibitive without the ability to make a profit on the tool cost. It is true that the automatic relationships that the Revit program creates are both really good and really bad. Initially the ability to keep track of everything seems to allow for greater control of the end product with less having to remember to do it myself. This condition gets quite disconcerting as the model progresses. Toward the end of the process so many relationships exist that the model manipulates things that are locked together from early conditions that getting the last changes is a real problem, i.e. moving something that should not move as it is conditioned to be attached to something that has to be moved.

Many other constraints that were just not productive. The biggest difficulty is Autodesk itself - they just do not give a hoot about an individual user.

Very interesting, Lew. Glad to finally hear something from someone who not only used Revit, but used it on significant projects. Will be good to meet you and hear more details at ACUWest's ArchiPub "sessions" in March.

Cheers,
Karl

If you want to see "the other side of the fence" take a look at, for example:

http://www.rugi.org/cgi-bin/webbbs_config.pl?read=529

Also, http://www.rugi.org/cgi-bin/webbbs_config.pl?read=574

Not that I agree with all he says ... but then, we agreed that a completely unbiased opinion is impossible to obtain.

Thanks for the links to the "other side" Djordje. I will continue to evaluate both AC and Revit over the next 30-45 days before making a final decision. I'll let you know what I decide and the reasons for my decision. I'm sure I'll have more questions for you guys in the mean time.

Thanks.

Only a bit biased. 😉

I'm having a hard time finding any truth in this statement:

2) Revit's Family libraries are always able to be manipulated and custom designed by the user to create variations of the templates provided to you. ArchiCad's libraries do not at this time as they are stagnant and unrevisable. ArchiCad users can only select from a choice of libraries instead of creating / designing new components.

Well ... at least, here the resellers/VARs/whatever are if anything more critical of the softare, and are (seemingly) more realistic. I find it hard to find any truth in any of Mr. Loreto's statements - the one about views not being dynamically linked made me smile. If he meant the rebuild times for the S/E and the 3D, then there is a point.

Interestingly enough, NOBODY mentions the linking rules! Also, nobody mentions CDs.

But - this does sound too idealistic - as I posted there, it is really the struggle between BIM and Flatland, and in that battle both us and Revit users are on the same side. Their problem is, that Autodesk considers its userbase solid and homogenuous - which it is not. Switching to Revit or ArchiCAD from AutoCAD and basically 2D work is the same process, in which I really do not see how the logo on the box helps or hinders the transition.

There is quite an interesting PDF whitepaper on the Web (lost the URL) on what to do to switch the office to Revit from AutoCAD. Search & replace - word for word, it is applicable to ArchiCAD.

The ultimate question arises: why did the people notice only when Autodesk started yelling?

I found either no truth or at most half-truths, so we mostly agree, of course.

The half-truth that I thought he was going for in the statement about dynamic linking is this: in Revit, all windows are 'live' so you can see the effects of your actions instantly in any of them, much like many other traditional 3D solutions. For example, if you have a plan view, a section view and a 3D view in Revit and you select a wall, then that wall shows as being selected in all 3 windows at once. If you then move it, it moves in all 3 at once.

We do not have that ability in ArchiCAD (and obtaining that behavior in AC isn't just an issue of more horsepower - it requires some major software redesign by GS - not only in terms of multithreading, but also in terms of the concept of 'rebuilding' - which at the moment is a complete rebuild, and which must be an 'incremental' rebuild to support a feature like this, rebuilding/redrawing only the effected elements.)

Hi all,

I am a full time user of Revit, and I currently own and operate a design studio. I belong to Zoog Design forums and came to this board at Djordje's invitation.

First, I would like you all to know that I hold Archicad as being responsible for getting me into this industry. I started doing studies on building cases about 8 years ago using an educational copy of Archicad (forensic, as a building official). I loved it. I transfered the CAD skills I garnered in Archicad over to Autocad when I bought my first copy of a cad software. At that time, I had no need for bim (or awareness), and could not justify the expense for a tool used occasionally for analysis of existing buildings. At some point in the future, I would like to re-aquaint myself with Archicad, and really see what it is made of. I truly respect and admire the product, and so I feel I am in a unique position to respond here.

Second, I come here to try to straighten out some brewing misconceptions about the two softwares, and their devotee's.

I think it is unfortunate that visible (to potential buyers), vocal individuals are spreading mis-information and fud about both programs, in both camps. Over at Zoog, there are and have been numerous threads with titles like "More Archicad Propaganda", etc. Likewise, here, in this thread, I see comments and speculation about Revit that are blatant untruth's.

So, rather than "attack the man," or attempt to discredit individuals statements, I would like to open myself up to your
valuable questions in an attempt to create the mutual respect between the camps that Djordje refers to when he alludes that we are the only two true BIM products on the market and share a mutual vision.

Please, before you blow me off this board, or attack this man, allow me the opportunity to clear some air, as I am an invited guest.

Bill
