I need help with BIG SITE. I HAVE 6-7 big residence apartment !!!

[beratfazlija]

Hello everyone i need help/solution with a big site around 6-7 big residence apartments, they have a quite big floor plan i need to combine all together in one site but it's kind of difficult to make that happen, any suggestion how can i realize this project ?

Thank you.

If you have the apartments modelled in separate files, then bring them into the master site file as hotlink modules.

Is the site big or is the project?

What @Barry Kelly suggested works just fine if you are modelling them in a separate file then linking them into your main model.

Although, to be fair - if it's just 6 or 7 apartments on a single floor then I would model that in one file.

If you have a building with more than 5 or so floors and 6-7 apartments per floor then I would go the Hotlink module route.

It all depends on the complexity.

I am also wondering why you have put this in the Visualization forum...

Me too.

But it is labelled 3D styles and Rendering.

So I am assuming the original poste want to do a rendered image of it?

Hey Barry yes i have the files separatet, how can i do that is there any tutorial about that ?
Thanks.

[beratfazlija]

Both to be exactly.
One building has around 50 apartments it has 5 floor plans, so i have like this 6-7 buildings, this is big project that is on going project some have started etcc. so i need to do a 3D rendering for this project.

You will need to research Hotlink Modules.

There are many posts here, but also go to the Learn portal ... https://learn.graphisoft.com/

Do a search there for ... Hotlink

There is a 'Hotlink Management Guide' that is free if you have an SSA or Forward subscription currently.

Hi Beratfazlija,

It seems you may only be looking to bring them together for rendering?, but you may want to consider structuring the 'campus' of apartments as outlined below to have accurate views from various points.

For multi-building ‘campus-like’ sites and surveys, I’ve found the approach below (brought to me by a surveyor and civil engineer many years ago) works very well, both in work flow flexibility and accuracy. (In the project we worked on, the urban campus with several buildings across four city blocks proved accuracy within a few inches for each structure, affected mainly by the actual construction margin-of-error).

1. Keep the surveyed site in its own PLN at true north with your ‘campus’ plots amply in the  +/+ quadrant  (as typical from the surveyor or civil engineer.  (Civil prefers it that way, too, and you can overlay other surveys and aerials with ease.)
2. For each building, whether existing or new, establish what we can call a ‘building origin point’ (BOP) and a directional rotation value on that point to site each structure. (The most convenient BOPs are easily surveyed SW corner or grid intersection.)
3. [If any of these buildings are designed by separate architects, you will want to issue these values for use on their project/s, often via a 2d or 3d file they can reference in.]
4. Model each building orthogonally in its own PLN with the BOP noted. 
5. When full multi-building site visualization or coordination is needed, the buildings can be hot-linked into the site using their respective BOP.  Once anchored, simply rotate each building file on its given BOP to match to true direction.  (Note: Other file types can also be brought in, such as PLN, RVT, IFC, SKP.)
6. Site MEP can follow the same logic, in areas belonging to the appropriate building project BOP or an assigned block area of the site.

Hope this helps.

Thank you @beratfazlija - that clears things up.

I terms of model coordination I would assume that you have the placement of each building on your site sorted out. Otherwise what @Marc H suggested is a good start to get your model in order. In our office we have projects very similar to yours - somewhere in the 200-600 apartment range split over several buildings. The key is to think about what is important for the output you want to achieve.

Typically we follow the following link strategy:

Bath/Kitchen > Apartment > Building > Site

This allows for different output from the relevant models and without having excessive information. I would also advise you to draw a model-map as to which modeules/apartment types are hotlinked into which building so that you have a good overview of how your whole model is constructed. But, the linking aside - I would also like to suggest a few other things.

Firstly, if you are doing exterior visualisations/renderings - do you need the actual apartment layouts in your model?

Being able to turn off your apartments and only showing your exterior skin should greatly improve your rendering times.

If you need interior renderings these can be done separately - no need to do that from your main model.

In short - consider your different outputs and let that be a part of how you set up your model structure.
