The problem with simply hiding them is that the connecting face can also bleed through. nr, under the OpenGL settings, is there any better antialias setting? Not as if any could do wonders with this (from a distance, they would bleed through even with a roof thickness) just asking...

It sounds like you have a Z-fighting problem. Meaning there are two faces occupying the same space. If this is the case you need to "cut out" the offending hatch. Do you have an image or could you upload the skp for us to look at?

What does it mean: "It don't work." Maybe you're using Windows and have enabled hiding file extensions. You should disable this in Windows. azuby

These should help (from SU5...I don't know if you get the same warnings in SU6). This drove me NUTS when I first started! But the logic is sound: SU is saving you from accidentally drawing coplaner faces...makes you do some grouping on purpose. (There's another little bit of nightmare if you group an edge adjoining 2 faces with one of the faces, then put the group on a hidden layer...you can't draw a second visible edge over the hidden one: you'll have to move the group so SU draws it for you :`) [image: JnBE_Image1.jpg] [image: UjBx_Image2.jpg] [image: jcBQ_Image3.jpg] [image: PP6G_Image4.jpg] [image: KP4Q_Image5.jpg]

That worked great. Thank you very much.

first guess: try to switch "transparency quality" in the style window (edit tab > face settings) from "faster" to "nicer". second quess: if you have grouped your fence and outside of it is another face in the same position, SketchUp may get confused which face to display. if that is the case, just delete the additional face. could you post your model? would be interesting to have a look at it...

Hi, It seems you need XrefManager script don't you ? -> Add Xrefs and Manage Xrefs, Autocad-like tools to insert and manage external references within SketchUp. Version 5, requires -win32ole.so- in the Plugins folder. Documentation included. d/l here: http://www.crai.archi.fr/RubyLibraryDepot/Ruby/em_fil_page.htm
