1st parametric AEC CAD

[Rob]

I just would like to know (curiosity) why Revit claims to be the 1st parametric AEC CAD on the market since 1997. Is that true? or it's just another misleading marketing slogan? What about GDL then, wasn't it parametric before AC 6 got released?

seems pretty qualified to me:

This guy is a senseless *.* and I am bewildered of his position. He has never took a CAN risk seminar otherwise he would know that what he blurbs is nothing less then a request of giving up the base of the profession, that is the License.

I am equally bewildered by this paragraph below.
How can Autodesk claim to be leaders in the IAI and IFC movement when everything I have been told seems to be the opposite?? who is kidding us??


"Direct exchange of building model data with other applications is essential if the models that designers create are to have value beyond the generation of traditional drawings. Autodesk is committed to supporting industry standards for integration and interoperability. We are a founding member of the International Alliance for Interoperability, and support the implementation of Industry Foundation Classes, as a data exchange mechanism, in all of our products. In addition, we support a variety of other open standards for data exchange and integration, including CAD file formats such as DGN and DWG, published formats such as DWF, other data exchange methods including ODBC, and a number of XML initiatives.

IFC is supported in ADT (Architectural Desktop), but not as a free plugin. You have to buy it to enable it.
Revit doesn't even support IFC (but I guess/hope it will in the near future).
So as a "data exchange mechanism" it is certainly limited in Autodesk software.

Sorry to draw up an old thread by i'm in a bit of a pickle.

As some of you may already know i'm currently completing my thesis on BIM and the future of architectural documentation and construciton.

As part of this i'm doing a brief summary of Revit and ArchiCAD explaining their Building Information Modelling features and how their approaches differ.

This is not a comparison of the two systems, it is more an explanation of BIM using the two systems as examples to explain how they work and their BIM features.

As i've been using revit for 5 years I've got a pretty good grasp on how it works and i was wondering if someone could help me out with an explanation of ArchiCAD as it pertains to a BIM?

Unforuntately i didn't realise my lack of information til today... My Thesis is due tomorrow so quick replies are appreciated. If i don't get anything i'll have to make use of person experience with ArchiCAD 6.5 and online reviews of the individual releases, which i really dont' want to have to do.

Thanks in advance.

You're like me. I don't like to leave things to the last minute either.

One never means to leave things to the last minute it just turns out they way because of other deadlines!

Would be great if you could help out. Even if a few people wrote a couple of small summaries that could be combined and elaborated on.

What are some of the parametric differences between ArchiCAD and Revit?

Some way to revise a really old thread.

Most important different: parametric relations between objects in Revit stay associative.

In ArchiCAD, there are very few parametric relations between objects:
-- cleanup of corner/joints between walls
-- Solid Element Operators
-- accessories tied to objects

That's about it.

In Revit you can define multiple connections/relations and constraints:
-- aligning ANY element against ANY other
-- attaching wall heights to stories
-- distributing objects to have equal distances in between
-- etc...

If you find this important, the difference is huge.

Thanks, I'm a little new at both the softwears. I was taught on ArchiCAD, but my job prefers me to use Revit (which I'm learning on the fly).

SoftPlan has been parametric longer and more fully than ArchiCAD or Revit.

ArchiCAD in not fully parametric. You can not change a dimension and have the wall move to match the dimension as you can with fully parametric progams like SoftPlan. SoftPlan has also has had voice recognition since about 1995? You can work by voice commands if you like.
I didn't like it but it was fun for the clients. They liked the presentations by voice command and seeing the changes made by voice.
