How "hard" are SEO for ArchiCAD

[Anonymous]

I have a situation,
i need to subtract column from foundation to get clean intersection.
I have only one section where I need to show that clean intersection
and have more than 80 columns and foundations,
so shell I SEO all the columns and foundations
or just the one couple shown in section?

How complicated SEO is for AC?

I would since I like the model to be as accurate as possible. It is only one section now but it might be a couple next week. Also doing it to all of them avoids the question of 'Why are these columns different from the others' down the road.

If its 80 columns and one foundation, it's a very simple process. Nearly as simple as just doing one column.

Open the SEO toolbar...

- Select all the columns, click 'Get operator Elements'
- Select the foundation, click 'Get Target Elements'
- Choose the operation (I'd stick with 'Subtraction')
- Click Execute.


If you have more than one foundation to SEO from, I suggest a seperate SEO process for each foundation piece and only the columns that intersect with that piece. Otherwise, a lot of operators acting on a lot of targets that they don't intersect with will unnecessarily increase lag in the 3D window.

Tnx for re
but I was asking if 80 different SEO
are complicated for AC and will slow down exploring 3D model
Is it to much calculating for archicad every time I open 3D window?

They are not.

Just to see what the limits are I once selected all the ceilings on a floor of a hospital and subtracted all the lights and diffusers. That was VERY slow, but there were hundreds of ceilings and probably a few thousand fixtures.

And they'd have to be solid objects to subtract, right?

The biggest mistake I see people make is rather thoughtlessly grabbing multiple targets and multiple operators , creating an unnecessary 'matrix' of operations. All the walls trimming to all the roofs for example.

At the end of the day I think the more operations you have the more ArchiCAD will struggle to keep them updated, but even then it would take a few hundred to notice.

I'm sure the complexity of the operation would take it's toll too. For instance a diffuser is most certainly going to be more taxing than a square column.

My "diffusers" are actually just simple blocks which serve as placeholders. The actual parts are modeled by the electrical guys.

Of course. It's easy for people to forget the 'Solid' in Solid Element Operations though isn't it? The operator needs thickness and in the case of many objects there isn't, so an SEO won't work as may be expected.

Still some improvement to be done with SEO, but that's another story!

Calculating the operations for AC is one task...
Second part of the story is new polygons....
Does SEO make new polygons?
if so, all those new polygons are making model much more complicated...
