Archicad is slowing down while extending curtain walls scheme grids

[aryastark]

I can't use Archicad. 😞  it even not use CPU or ram but while drawing the scheme grid only Archicad stucks. there isn't slowing problems rest of the programs. even while Archicad is stuck I can use pc smoothly. 

when its size is smaller drawing scheme becomes faster.

if it gets larger at one point impact-response reaction time gets very long. for instance pet palette showing 10 seconds after clicking the edge of the scheme. 

I tried to tamper with these settings. not helped.

How big is that? 😳

Looks like hundreds of cells... The CW tool might not be optimized for sizes that huge.

Just split it up for the moment maybe.

You don't even use most of the grid. So I imagine that slows it down quite much.

it begins to stuck when the size get about 60x20m rectangle and if it further that, becomes impossible to work with. so... separation method is necessity.
