ZOOM ISSUE

[Martin Jules]

What could be the cause of the following issue in ArchiCAD 29?

Operating system used: Windows

[Jan Millan]

It could be a "far from origin" issue.

is this an exploded DWG? my guesses are:

-extents too far from 0,0,0

-excessive content in a single view (have seen similar with 100,000 fills/lines/etc. in a single worksheet)

-scale issue (contents of dwg at large scale, then reduce view's scale after exploding)

...

more than likely it's a work-environment bug that should sort itself out after restarting.

I used to work with real world coordinates in ArchiCAD, and I've never had this issue before.

I am not psychic, so I will guess what that is.

if the problem is when panning, or zooming in and out, the screen gives a lot of cropped versions of itself, like drawing part of the image and not having time to finish the image then drawing the next bit of the image as the screen moves, leaving fragments of the image, making a mess that persists?

when that happens to me, I think it is caused by a screen graphics layer/channel error/issue of the graphics card, so I move the Archicad window to  a different screen, then back again, and the problem goes away.(yes on a windows computer)

The reason I'm guessing this is because the zoom is 1541%, the lines vary in width, and seem to be oddly parallel, with neat slices like they are from the screen cropping edge, almost like its a single element being dragged across the screen while zooming in and out. 

And because I'm not psychic, I don't even know if that is the question from the image and description.

I'm sorry I can't help.
