When we are at it, really... Is the reason of your modelling this way to display "raw" brickwork and then plastered/painted version? There could be other ways - or at least combine them. Use layers for instance to hide certain elements (like the brick walls when you display the plastered version).

Hi Gai,
Thanks a lot for the info about possibility of erasing line with shift+erase - it helped me a lot.
(I think it's application problem but now i understand how sketchup works...)
exaple for hidden lines...
Now I understand also z-fight and I know how to solve my building...
Maybe it should be helpfull in any new version of sketchup to have possibility to solve z-fight with "bring to front" technology and not showing the lines what are under other area - but i understand it should little slow down the alghoritm...
Thanks for the help.

Hi, I am including my skp file (my planned house)...my house plan

There is no "bring to front" setting in SketchUp unfortunately so you will need to solve this by modelling. Can you attach the skp file as well?

As for edges "bleeding through" - that's a different issue. An edge is always displayed at 1 pixel on screen. Now if you have two faces very close and zoom out, the distance between them will at some point be smaller (on screen) than 1 pixel and the underlying edges will start bleeding through. You cannot really do anything about this but

1. either hide those edges (use Shift+Eraser)

1. or do not care but when exporting an image, export at a higher resolution - when that "gap" would cover more distance than 1 pixel.

Hi
Really now i seen that difference is less. Is it possible by any way to "bring to front" any area?
But other question. Line (window corner) in the wall is more than 10 mm from the end of the wall
but if i look from large distance, I seen the line...
Is it any setting in Sketchup or is it any possibility to not see lines what are more than 5 mm under area?

Hi Dalibor,
This phenomenon is called "Z-fighting" - Z means the depth "offset" of objects (materials) and in 2D applications, you generally have some option to "bring to front" or "send to back" etc.
In 3D applications like SketchUp, this should be done by giving real thickness ("Z value") to objects and when two faces occupy the same plane, SketchUp cannot "decide" which to display thus the "fighting" of these materials.
Now you say that they are 5 mm apart from each other. I am not sure... To me, this does not happen if I move one of the faces 5 mm above. Are you sure there is no other face in there?

Hi All,
I am just trying to make a sketchup model of my house, but I have a problem with opacity of materials. Even if I use materials with opacity 100 I still see some textures or lines on the area under it, even if I am looking on it on longer distance...
I use standard textures and colors provided by sketchup with opacity 100. This problems occurs particulary if I have in group material what is under area and material what is up the area... (distance between these materials is e.g. 5 mm or less)
Maybe it's only any beginner's error - i tried in on sketchup 5.0, 6.4 and also sketchup 8.0 with the same reason... Can you help me pls what I do incorrect? Thanks forward...
