HELP! 2d plan performance is SO SLOW!!!!

[Anonymous]

BIM Managers!

I need some help.


I have one project with unacceptable 2d plan performance. I’d like someone to open the file, and determine why it behaving so badly, and adjusting the file so that it is usable again. (DM me please with a consulting proposal if this seems suitable)

Some links of note:

Original Archi-Talk post/cry for help.

Link to a screen recording showing the problem. Note, I turned off 2d antialiasing in an effort to improve performance(it didn’t) before I made the movie.

And here’s a link to a .PLA. (please forgive the modeling quality. The model continues to disintegrate in my efforts to repair it):

In an effort to find the problem elements, I deleted all the walls, and pasted them back in after cleaning them up. The walls file ran smoothly, and the file without any walls ran smoother…. But the poor performance returned once the walls were reintroduced.

I’ve already gone through an Archicad audit and received some advice from GS Tech support (they say my file behaves normally and my computer is too old, although none of my other projects perform so badly).


Here are some of the behaviors that trigger a 25 second slowdown (spinning beachball)
Changes to Graphic Overrides, Model View Options, Reno Status ( Existing plan doesn’t trigger slow down, only views with new elements.)
Go up/down a story following change in Reno status.
Change layer combination after change in Reno status
New Reno status after change in layer combo.
Pan - zoom or Zoom - pan. Although if no other change to 2d setting, this pan and zooming works without lag.

My IT consultant is looking into adding an external graphics card, but again other files with nearly 5x the polygons behave fine.

My colleagues had a similar issue on their file some time ago that has started in a later stage of the project. Both projects are running on the same TW server and when my colleagues started having this issue a couple of weeks ago, our file was running smoothly.

Until now. Even if there have not been any significant changes in the project/model/MVOs/GOs/SEOs.

I usually do as you say and "destroy" the file until I find out what causes it.
