Can some one take a look at my complex profile?

I guys.
I have created a couple complex profiles and ever since i have started using them my whole project is just getting totally weighed down and lagging.

I have proabably between the profiles attached - only 15 walls with them in my project- the regen time is silly long, and it is quite hindering.

So any who can some one check thes eout for me.
I read in a previous post that not having blank spaces is best to reduce polygons, so I filled in my blank spaces with empty fills and no outline, i also got rid of some of the detail in hopes of making it simpler and faster- no luck- but if you notice, that is why they look off .

Thanks Jess


- ugh, i cannot attch an .aat file- so if you think you can help please pm me.
Thanks again

A quick glance reveals not only lots of fills per profile, but also a lot of extra nodes in each fill. Try getting rid of all the extra nodes, so that there is only two nodes per edge (one at each end).

And your IPR-16" Fnd Wall. Stn Shelf. No Int Fin profile still has a void in it between the masonry blocks. This will add to the polygon count.

Cheers,

Interesting to study this; I learned something new.

Drawing a single wall with your 'IPR...stud gyp' profile resulted in a Polycount (goodie download add-on) of 25 polygons for the wall.

Seemed excessive, but you'd have to run polycount on your whole model to see if this is the problem. (The 3D people in the library, for example, have over 6,000 polygons each - heavy burden on AC.)

One error is yours, reducing it to 23 polygons: there is a small air gap between your footer and the insulation/stud fills above. You can see it in the attached screenshot taken from the internal engine 3D window in hidden line mode. I recommend this mode and polycount for tracking down complex profile issues.

At the top of the screenshot you'll see some more red arrows. There are two more polygons because the gyp doesn't reach the top of the wall form. That might be intentional, or not. But, what about the lines on the top of the wall - and there are a couple more on the opposite side, not seen in the screenshot?

Why is ArchiCAD making these areas of an otherwise flat plane separate polygons?

Custom edge materials.

Turns out that if I assign the same material to the entire profile, all of these other edges go away, and the polygon count is reduced to 16 (or 14 if the gyp meets the top of wall).

Make sense. But, it doesn't make sense that you'd ever render the top of this stem wall I don't think? So, I would avoid assigning separate materials to the things that will never show in an image. Separate/unique fills still show up fine in sections as desired, and you cut your polygon count.

In my experiments today and a few weeks ago, I found that the extra nodes on the edges don't affect the polygon count. It is annoying that the profile editor creates them and they make subsequent editing tedious, since you can't stretch an edge nicely until you get rid of them, but no polycount affect.

Similarly, it does not matter how many fills you use. Suppose you have a rectangular profile and you have dozens and dozens of fills making up the rectangle. As long as there is only one material assigned to the profile edges, a single wall with this profile will contain only 6 polygons! Yet, a section will show all of the fill details.

Great to know Karl - thanks for doing all the testing!

Ha! I know what you mean - it's Australia Day and I'm on the computer. That's it - I'm off to the beach!

Cheers!!

Thanks so much guys.
I will change the materials.
I only had them different because I could.

Good bit of learning here.

Thanks again for your time- I hope Australia day was fun.

And Karl- most using archicad need to get a life,
