Serious lagging

Anonymous — Fri, 06 Mar 2020 15:23:26 GMT

Archicad is lagging a lot on a recent project which is not that big. i checked the task manager and the only thing that seems to be working really hard is the ethernet connection. i guess Archicad is trying to read something from our server?
other than that, its using 2gb of ram and the cpu or gpu is not stressed at all.
The only thing i can think of that is producing this lag are two or three models that were imported so the polygon count might be a bit high? the models are not complicated..

its really annoying though because every 3d software out there is capable of handling millions of polygons but when you import 3 chairs or tables in Archicad its starting to lag.
i dont know if i have a question, but maybe someone can explain this lag

i had a similar problem, with a problem object,
it was suggested to me to convet imported objects to morphs. At the time I didnt get a chance to try the fix, I just deleted the object.

Very high number of polygons can definitely cause slowness so that is one area worth looking into more thoroughly. You should use the Polycount Tool to figure out the exact number of polygons:

It is part of the Goodies package which can be downloaded from here:

I'm having a similar problem - a project file is starting to run slowly. I've tried using the PolyCount tool, and I'm able to see the offending object, but I'm not able to change the LOD (Level of Detail). I've added the object (a tub I downloaded from mfr - Victoria and Albert) to our office's library, still no luck. Also tried opening the objects GSM settings using the File\Libraries and Objects\Open Object command to open it for editing (CTRL+SHIFT+O) - no luck.

I've attached a screenshot of what I'm seeing in PolyCount.

Thanks all!

Matt

I wouldn't say that is an exceptionally large object - bigger than most but not massive.
If you delete the object does the responsiveness come back?
Or if you start a new file and add the tub, does it slow down?

This will help you to determine if that object is indeed the problem or not.
