Hello, my name is Laszlo Nagy. I am a practicing Architect and I am also a long time and passionate ArchiCAD user.
I have been using ArchiCAD since 1995. The first version of the program I used was ArchiCAD 4.5 and I have been using it ever since, always keeping pace with the latest versions.
I have been working for Graphisoft since 1997. Graphisoft is the developer of ArchiCAD. I have been working for Graphisoft Technical Support for over 5 years, first as a full time employee, then later as a freelance consultant. I had the chance to delve deeply into the workings of the program during these years so I gained a lot of information about how the program works - information that may not be easily obtained by a regular user.

I have always been interested in creating materials that explain in simple terms the full capabilities of the program so anyone can grasp it easily and use it very effectively.
I have created thousands of pages of training materials over the years on ArchiCAD. These include various segments of ArchiCAD's Help files, dozens of articles available on the internet, free training materials provided by Graphisoft etc.
I am the Moderator and Site Administrator of ArchiCAD-Talk, the largest ArchiCAD User Community Forum on the Internet. I am also a regular contributor on the Forum with cca. 2000 posts.

See some of my references that have been published on the Internet:

I have always been a firm believer in understanding the basics of the program very well. This way one can get the full benefits of what ArchiCAD has to offer in terms of productivity, effectiveness, saved hours, avoided mistakes, saved redesign costs, met deadlines etc.
 

As I have found over the years, most architects and other professionals using ArchiCAD are not aware of the full potentials of the program and therefore do not use it as intended. Many people switching from a 2D drawing program try to continue to use ArchiCAD as they used their previous 2D program. As a result, they spend much more time working in the program than they should. Only if they knew how to use the program properly, their productivity would increase dramatically.

Even people who have been using the program for many years are missing important basics. As a result they use more complex ways of performing certain tasks or they do not use various parts of the program at all for lack of understanding.

One of the biggest problems is that there are many things in ArchiCAD they do not know they SHOULD know. For example, many people do not receive proper training in ArchiCAD, they just learn or figure our the program to a certain degree on a hit-or-miss basis. In other cases, people had proper training but only about the basics of the program and they are not aware of many more advanced features that can help them in their everyday work. Also, when new versions of the program are released, many users may start using the new version but do not get themselves up to date on the new features, which is again lost productivity.

Another problem is that many people do not understand the concept of BIM - Building Information Modeling. They do not know what it means, why a building should be modeled in 3D instead of being drawn in 2D, what are the far reaching benefits of the BIM workflow over traditional 2D drawing workflows etc.

The transition from a 2D to a 3D workflow has already been done in many industries, including the auto industry. In order to stay competitive, users of ArchiCAD must be able to use it as a full BIM application - they way it was intended. The whole building industry is moving to BIM - a process which cannot be ignored and which will only accelerate in the coming years.

Let us just see one very short example of the enormous advantages of BIM over a traditional 2D workflow:

Yet another thing that happens is that users just plain do not undertand certain parts of the program. It may not have been explained to them too well or they did not see its benefit at first so never really started using it, or it was a very new and strange concept to them - there can be many reasons. The end result again is that they do not use certain features and this causes at least 20-30%!!! loss of productivity in that phase of their work.

Let us see one feature of ArchiCAD that can save you a lot of time:

Therefore it is essential for any ArchiCAD user to fully understand and utilize the BIM capabilities of the program.

Imagine if you knew all the ins and outs of ArchiCAD so you would be that much more efficient in all parts of the program. Would you become 50% more productive? Or 100% or 200%? Whichever it may be, it is true that a fully trained professional is always light years ahead of his/her less trained collegues.

My long term aim is to help ArchiCAD Users become very proficient and effective in ArchiCAD.
It does not take years to achieve proficiency in the program. It only requires that you have a good grasp of the fundamentals on which to build. And this can be acquired in weeks.

I hope to be able to be assistance to you in becoming an ArchiCAD pro.
