Beaucoup des SEO's?

I'm starting a project that could involve hundreds of SEO's. Some years ago there was some observation that an overabundance of SEO's could start to bog down the model and maybe lead to erratic behavior. Is this still true to any extent?

Thanks

It depends on how much waiting for things bothers you. For a really impatient person, I think their behavior could become quite erratic and co-workers might want to leave the room! 😉

Sorry, couldn't resist. I've never used more than 100 or so, and have noticed some slowing. I believe it might have been Link who had made the observation on the slowdown with large numbers of SEO's ... so, joking around aside, I too would like to hear his and others' experiences.

The last time I used SEOs extensively was on the competition project decades ago, in AutoCAD. Cost me two consecutive sleepless nights ... so thank you, I still feel the effect, and try to go without SEOs as much as possible.

It is to be expected that a lot of SEOs will slow things down; plus the management of the layers ... good luck.

I have never experienced any problems with mass SEO's myself, and I've heard of others having up to 300 SEO's and not experiencing any performance issues.

My advice would be to use them wisely. For example, don't go selecting all your walls as targets and all your roofs as operators, and subtracting with upwards extrusion. Select only the wall(s) and roof(s) that are necessary for that condition, then move onto the next condition. And so on. It seems that having many small SEO's is easier for ArchiCAD to manage than a few SEO's that have many operators and targets.

Hope that makes sense.

Cheers,
Link.

This is exactly why I got swamped in AutoCAD once ... I had a huge elevation wall punctured with blobillions of any shape you like openings.

My highest count in ArchiCAD for the tie being is around 250 and no slowing down worth mentioning ... that is, that time that you can't replenish a coffee mug in 😉
