Handling a Project with too many OBJECTS

Anonymous — Tue, 23 May 2023 15:23:14 GMT

I HAVE A PROBLEM HANDLING A LARGE PROJECTS with too many objects like chairs, lights, Trees and a big landscape

i wanna know it theres a kind of handling that improve the proyect or someting else like instances of an object

can someone gave me some tips

i use archicad for a 3 years and this is my basic problem and the complex modeling forms but for now i wanna solve the handling first

example :

i have a 5 stories building with a couple of chairs, bla bla bla when i generate the 3D visualization the machine or crash or the program not responding or the 3D generation will be in 128 minutes

my basic hardware are :

AMD AThlon XP 2,200+
512 DDR
120 gb Hard diskdrive
Nvidia Gforce fx5200 128mb DDR

To start, let's goose up the RAM. If you're doing complex projects you need at least 1GB DDR.

I'm sure you'll get lots of tips on this question but here are some things I consider really basic. When I hear similar complaints from my ArchiCAD clients these almost always make them happy.

First, include only what you will see in the view. Remember, the more points (nodes -- think nodes!)in 3 dimensional space the computer has to calculate, the longer it takes. So...

If you are doing a view of a hotel lobby, for example, marque off the area so the computer isn't calculating the whole hotel for a view of the lobby. Even for exterior views, exclude things like trees that won't show up in the view, like behind the building (trees kill you... they have godzillions of nodes -- think nodes!). And take a look at the Elements to Show in 3D dialogue box. (Image menu)

If you are doing things like exterior views, turn off layers that represent objects (including walls) that are on the inside of the building; again think about whether or not you will benefit by using the marque.

There is almost never a reason to use an Infinite View when using the section elevation tool. If you are doing an elevation, limit the depth of the elevation to include only what you will or need to see. For example, doing an elevation of the front of a building and including (letting the computer calculate) the 150 trees behind the building that you won't see will kill you.

If you are using ArchiCAD's internal 3D engine things like Vectorial Sun Shadows take time. I'll let others comment on setting everything in the photo rendering settings to best with extra accuracy.

But one thing about rendering large buildings... you can set up the view very quickly using wireframe in the 3D window and then render. As a matter of fact, I often recommend that clients who just want a quick idea of how its massing is working out, set the 3D window to wire frame and render the building with Flat Shading, Good Ant-Aliasing, no Emissions, etc.
It's usually quicker than a shaded view in the 3D window.

Good luck...

With many Library Objects (e.g. furniture) you can set the 3D parameter of the object to OFF. So in case you don't want to see chairs or bathtubes or toilets in 3D, you can turn their 3D representation OFF.
That also helps to reduce the number of pieces to be modelled.

Don't forget simple things like working with layers, being pragmatic about what goes where can also save you time.

Examples include elements on internal layers switched off, while you render external views. Combine this with the other suggestions and your way in front.

A couple more:

- always do the layer combos for interior and exterior views; save as many views as needed, one for each view - they also preserve rendering settings, backgrounds, etc
- since 8.x, DO use OpenGL in 3D; infinitely faster than any analytic 3D
- always marquee off the part of the design that you are working on
- if your interior elements have rounded parts, set their resolution to 4 if they are not in close up; really good GDL objects know how to get less complicated when far away
- don't model anything that in the final rendering will be smaller than 10 pixels
- if you use trusses and spaceframes, set the resolution to 4. They will look EXACTLY the same in a view as the rounded ones
- don't use 3DS or DXF objects; use the time you loose while generating them to learn GDL
- invest in ArchiForma
