Z fighting
Helen269
With the time before I was able to find it easily but it was still
inside the model and not visible from the outside. The reviewer must
have used a section plane to look inside and when I did that it was
fairly obvious where the problem was.
This time It's not so obvious and I have found just small instance of
Z fighting between two blocks of stone but you'd really have to know
where to look as it was buried right inside the structure of the
model. I would never have found it without virtually taking the model
apart stone by stone.
Do the reviewers have Z fighting detection software? How the hell did
the reviewer find that one small instance of Z fighting??? Could
Google not build Z fighting detection into the next release of
Sketchup?
Thanks,
Helen

Which model is it?
We don't use automated software for detecting Z-fighting. If it's not
obvious to you where it's coming from, it's highly probable that the Z-
fighting is a consequence of geometric compression in the model.
Surfaces that are parallel and closer than a few centimeters to each
other will collapse onto each other, with predictable effects. This
will not be visible in your exported KMZ, but would be visible in the
3D buildings layer. (We have ideas for something where you can see
the "final" 3D layer version of the building, as a preview, but it'll
be a while yet.)

It's this model:
http://sketchup.google.com/3dwarehouse/details?mid=58913d9f07527b0b98d57721771a77f9
This is the corrected model, the offending one has been deleted. The one bit
of Z fighting I found (after the first correction) was between the blocks on
top that have clover shaped holes in them. I modelled them with all sides
solid and so when it came to copy them by rotation the sides of the blocks
touched each other and must have produced Z fighting. I only saw one but by
removing the sides on the original and then re-rotate/copying it I hope I've
eliminated any other Z fighting in the copies. The same with the clover
blocks on the balcony.
Thanks,.

Hi Helen,

The model has just been rejected for the third time because of Z-fighting
that I can't see. Could someone please tell me where it is so I can fix it.
:-(

extruded, instead of 2D, and the two surfaces are very close to one
another. Delete one of them.

deleted..
However I now see that when viewed from a distance there is noticable Z
fighting on various parts of the walls and on half the green door.
These really are single surfaces with no other surafces touching them. I
even redid the door and push/pulled it out so it wouldn't be just a single
face and it still does it. This Z fighting doesn't happen close up though,
only when viewed from far away. I'm going to resubmit anyway and see what
happens. If it gets rejected again I might just start the whole thing from
scratch
