Wall/line dissapears - Can't see what I'm drawing!

I don't know if this is a problem with ArchiCAD or my PC, but lines, wall, ect. aren't showing up when I draw. When ArchiCAD starts up everything's fine, but if I swith to another tool, like a window or door, the next time I try to draw a new wall, the ghost image of what I'm drawing that usually follows the mouse pointer doesn't show. If I click two points, it does draw the wall, but its very frustrating not being able to see what I'm drawing.

Has this happened to anyone else? Anyone know of a fix?

Welcome to the forum James.

OS? Hardware? Version of ArchiCAD? Tip: If you put this down in your signature, you won't get asked every time.

Try going to Options > Work Environment > Advanced Redraw Options and play around with the hardware acceleration and anti-aliasing settings.

If that doesn't work, try updating your video card drivers to the latest stable version.

Thanks.

Sorry, I'm running Archicad 13 on a Core2 Duo E6550 @2.33GHz with an Nvidia GeForce 8500 GT and 2GB ram on Win XP.

I played with those redraw option. It seems to have worked. I just maxed out the Hardware acceleration and memory usage, left anti-aliasing off, and put model display on full. I've been playing around and it doesn't seem to be giving me any more problems.

Thanks for your help.

Glad it helped.

I ran AC with very similar specs till just a few months ago and while the walls and lines never completely disappeared, I do remember that I used to turn anti-alias on for a bit and and then off again to get rid of small niggles in 2D. If I remember right it was the "rubber-band" line that used to disappear on my PC.

I never did get around to downgrading the graphics drivers - I still just minimise the active window within ArchiCAD, then bring it up again. I must give it a go at some point!

Thanks Peter. Touch wood, the rubber bands are behaving themselves with my current configuration but it's good to know this trick just in case...

Thank (god?) for AC-Talk!
I just recently fried my old graphics card,
replaced it and forgot about it...
...and then AC started going all weird with the
rubber band/ghost of elements disappearing during move
and draw commands.
I thought I was going nuts -
pulled out all plugins, add-ons, free objects, my own GDL efforts,
re-installed - NADA - same bug!

oh, yeah - never thought of the graphics card...

what an idiot!

Hello.

I am re-posting on this topic.

Really weird issue. Archicad 16 on PC.

I've done hundreds of projects up to now with no issue.

And now when I start a new project everything is ok.

After a while as I design, I just stop seeing what I am designing. It appears only after I design it and it's there.

The wall doesn't show up as I design a wall, same with slab and almost everything.

Any ideas?

The weirdest thing is that when I start it is just fine, then after a while it does it (i think by itself).

I use dwg attachments if this has anything to do with it.
