Major display problem!

[propstuff]

I've just come across this with VW/RW12.0.1 on XP2; I haven't been able to try it on anything else yet.

If I zoom in to a fairly modest level, objects rendered in OpenGL and Final RW just dissappear!

In a new file, after relaunching VW;

A 6m ? circle Extrude will disappear in Open GL when the screen height is 15mm.(about 1600% at a scale of 1:1)

In Final RW it disappears when the screen height is about 30mm.(about 900%)

Changing the Layer scale effects the zoom level (because of the scale) but the physical displayed size (IE 15mm )at which it disappears is the same.

These are not extremes of zooming and must be able to display properly at those sizes!

I don't think this is something I've come across before.

Does anyone know what's happening??

PS

IT'S WORSE!

At a scale of 1:350 a 3m ? extrude will disappearin Open GL!!

I have had this happen for years... dont know the solution, but doesnt bother me so much.

I rarely zoom in on renders.

best of luck

Are your objects far from the origin?

Those of us who live by the 'Zoom' are often faced with this issue. Honestly, I don't have a clue ... when you get it figured out ... make sure to post the results ; )

What kind of video card are you guys using?

If you have sample files, please send them w/ specific information to bugsubmit@nemetschek.net

I've had this problem, too, and with many different hardware versions. Yes I think the power of the video card affects it, but to what degree in relation to the complexity of the VW drawing is upsetting. Screen still goes blank for me as described above, but at such a tight zoom that I don't care so much.

Just my 2?

Ray:

In the case of the 3m? deck dissapearing: yes it is a long way from the origin, but there's not much I can do about that: It's a large site and we're sub consultants. The co-ordinates need to stay for referencing back and forwards.

In the case of the 4m? test extrude I made that disapears at 30mm, it's on the origin.

Katie:

This machine reads as an ATI Radeon X600 (series) 400MHz 256Mb.

I'll send the file.

Kenneth:

Likewise; normally at very tight zooms, but this is not acceptable.

I can hardly tell the consultants that I can't send them an image of our proposed structure details because at 3m across, it's too small to see!!!

Equally, a 30mm detail of a 4m object dissapearing is just not good enough.

I hope we can get an answer on this soon.

I have this prob with 11.5. Never reported it.

I have the same issues with rendered display only. 2d lines and fill zoom into the thousands of an inch. OpenGL fails at 7579% zoom factor.

FYI:

This seems to have been fixed to a large extent with 12.5

In my test file:

Open GL will now display to 990,000,000%

Final Quality will display to less than this, but considerably more than before. (I haven't determined the extent.)
