creatig high rise buildings

since the building should be created by floors..how can I for example create a 60 floors model without having created a heavy file

What do you mean by a "heavy" file.

Hard drive space is cheap, so I assume you are not referring to file size.

If you are referring to the size of the 3D model for purposes of rendering, this is handled with layers. Separate layers for interior walls, casework, etc. allow these elements to be turned off for exterior rendering speed.

Building sections require most (if not all) the interior detail, so there is no way to save there. On really complex buildings I will often batch process these while I do other things, like have lunch or make phone calls.

All the rest, such as plans, interior elevations, etc. are handled quite well by ArchiCAD and should hardly be any slower on a large building than they are on a small one.

On a building of this size you would be well advised to have pretty fast and capacious hardware. I assume such a large project must provide sufficient fees to purchase this, if you don't already have it.

You can't, in any software.

Provided the building model is fully done, which is the only way to do it if you want to use it for the construction documents production, quantity takeoffs and other activities - that is what the Virtual Building is all about. Don't think about ArchiCAD work as the standard shell only modeling usually done around here in Autodesk products.

What does "heavy" mean? For example, a full 100000 sqft villa with full interior at Emirates Hills is in 20-30MB range; for a tower, 100MB or more is quite normal ... IF you use external 3DS or DWF 3D models the size may go anywhere, so don't.

What is VERY important is how you organize your model for various purposes, and that you irganize it so that it CAN be used for various purposes.

And, the most important - get someone to show you how. Much easier than trying to guess.

Good luck!

I need to make this clear ..... I am separating the project in stages ...so that during the proposal and massing stage the inner typical floors and details are neglected..

then in this case normallt how should I work...still by floors or only by mesuring hieghts to locate levels and external floors effects...to give the cloasest look of building..

at a very, very early masterplanning stage, you may want to make it out of one 'block' - simply to show massing. but otherwise, i think the answer to your question is yes - still work by floors: keep thinking ahead about what you are going to need to work with at the later stages of the project.

if the external skin of your building (the bit that you will be modelling for the first phase) is very similar throughout its height you can use the copy/paste commands found in the Options>Stories>Storey Settings... dialogue to do most of the work for you: simply model the basic floor components as necessary and then copy/paste them as you create new storeys.

you will have a slightly bigger model file than fudging it to look right, but you will also have given yourself the framework from which to quickly produce basic drawings at the next stage of the project.

with building information modelling remember that the more 'up-front' work you do, the more efficiently you can progress the project later. this is usually a trade-off which factors in things like the scope of the feasibility study, the time and resources available, and the likelihood of dramatic changes to the brief!

Actually I would think that you should use that approach only if your floors differ. Your primary way of doing this (in my limited experience) is to use Modules. That way if your standard floor changes, you only need to change your module and the whole building would get updated automatically.

What would probably work even better is to put as much of the building as possible in the module (core elements, and even other stuff) and only model individual floor-related items as needed.

Hope I explained myself correctly if not succinctly.

for identical floors you could also create a library part. With a bit of simple GDL you could modify the part to duplicate/elevate for multiple floors. Hence you wont need 60 storeys in your project just a many as there are "typical" floors, ie one storey will be 3-22 floor.

To make it even easier you could create a new library part which "calls" the typical floor library part, hence you will be able to easily update the floor and not have to change the library part script each time you update.

i totally agreed with Sergio's method. Use Module!!!!

Hi Djordje,

And I suppose this is considered mid-range housing where you work ?? You didn't happen to have anything to do with any of Saddam Hussein's palace projects, did you ??

Is there anyway we could see this project ???

It is, let's say, upmarket mid range. Mid range is usually half of it, with less finishing. Average house plot is not less than 100 by 100 feet - that is what the governement gives to any newly wed Emarati couple to build the house on.

This is different - it is |Emirates Hills development project, surrounding the golf course, where you can buy a plot, and build the house according to the developer's design guidelines. The owners are mostly expat businessmen and women.

The Springs are smaller, for example.

You can see a lot at http://www.emaar.com Lots of views and plans.
Look for Emirates Hills, Lakes, Springs, Arabian Ranches, etc ... quite a bit of freehold developments around here.

Now back to topics at hand ...
